The server / project is restarted now
There is a slow progress from rehab but not happy with the results yet. All of the recovering is very slowly with restrictions.

The RAM was tested in the first run and looking ok.

I will test some work too.

I really missed the last pentathlon. Hoping to finish the TF range of GIMPS work too.

server shutdown on 20.05.
In absence and rehab the project will be shutdown for a month to recover.

A full restart is planned after that if nothing else occured.

If you want to contact me in this time Iam still reached in discord forums.

Many thanks for understanding!

project update
After returning from the hospital after a stroke, there has been a little progress with health. in 3 weeks a rehab is planned.

project updates so far:

- cert update
- gimps reserved results have all been reported
- server backup

still to be done...

2 results still need to be reported
RAM check as planned since 2 weeks

Thanks to everyone for all the well wishes, I wish everything would be better, maybe we'll be back at full speed in a month

Server crash
The server crashed due a memory leak. The database was corrupt so restored from todays backup, it was expected but need to investigate which was causing this. wanted to fix this in 3d but came earlier. 7 Apr 2024, 14:56:42 UTC · Comment

New TF multiGPU apps deployed (issues fixed)
You need v28 to run it. There is only support for AMD and Nvidia cards.

To run more than 1 GPU you must have this cc_config:

news update on multiGPU setup
Our BOINC wrappers were already prepared on running the config but we missed a file change a long time ago. With the hint of the user CallMeFoxie and testing of user DeleteNull we are now prepared to run such a config on windows and linux except Intel ARC cards.

The big update is planned on Friday this week.

change for reporting primes at T5K
In 2024 we have updated the TOP5000 prime report guide / info mail. While SRBase is running PRST all the time all the credits are going to the PRST proof.

This means that a user must create a new PRST proof code and report the rest there. If you dont want to report a new CRUS code was created to report to the anonymous account.

New apps plan
We have started testing new applications for SRBase on a BOINC test server, which are already used at PG, i.e. PRST is intended to replace llr2. Since there are still some code changes being made, everything is moving around a bit.

What are the advantages of the application?
- no more restrictions on the speed of the Gerbiczcheck (at the moment there is a performance loss of up to 40%)
- native application, no wrapper needed anymore

The following errors from the wrapper are then history:
- restarts of the BOINC client do not reset the CPU time to 0
- linux wrapper suspend issue
- better progress bar
- other general wrapper issues

Running app_config.xml files that are based on llr2 would then have to be readjusted, otherwise errors will occur in the calculations.

A public test will follow, time uncertain.

Looking for a linux wrapper programmer
We are still trying to fix the suspend linux wrapper issue but no progress yet.

A short conclusion so far:

- the latest boinc wrapper code is working with suspend
- suspend is working on BOINC client (view status) but status failed in background on wrapper and app (running further)
- linux and windows source code (without the latest changes) are the same where suspend is working on windows

If you have some experiences with c++ and BOINC let me know. The current wrapper source code can be found here https://srbase.my-firewall.org/sr5/forum_thread.php?id=360&postid=8934

Linux wrapper suspending task issue
A user has reported an issue with suspending tasks on linux, the WU is running further, the problem seems to be since 2014 with the old wrapper but nobody have seen this yet. This is also the issue during the Pentathlon where some WUs took much longer than expected. After checking some logs the WU restarted after it was already finished.

If you dont run other projects the issue has no affect.

We are trying to fix this as soon as possible.

2021-2022 - 0 bases solved, 97 bases unstarted
in total - 25 bases solved, 97 bases unstarted

That was the worst year ever. Broken hardware parts, war and also a high inflation after corona which affects the costs.

The llr application has been replaced by the llr2, less work and no unnecessary doublechecks but with less performance. Intel ARC is now supported,
cuda12 apps for 4xxx cards are in progress.

The project has almost completed the 73-74bit lvl at TF, 74-75bit is in progress, which is now taking considerably more time.
The new CRUS goals for 2023 are available and some have already been set up.

I wish you all a healthy new year 2023 and of course healthy hardware!

The app divides the number 607920 / 51 = 11920. The gwnum lib has a bug somewhere and the dev is informed.

At the moment only S51 is affected.

Base S51 will be stopped for the time being after 35-37k is done, the tests are correct with the divided numbers but primes cant be removed from the sievefile.

All affected tests must be convert to the correct values. This takes time.

New llr2 app test
This test is using the llr2 app from primegrid but without certs. Win64, linux64 and mac64 is available. To get work you must enable "Run test applications" in your prefs.

For testing I have added base R88_250-300k for a double check for Sierpinski / Riesel Base app.

A local test with wrapper was successful on windows but dont expect too much.

Hardware failure
The power supply blowed up today and also lost a SSD due a power feedback, I was shopping today to get a new one as soon as possible. Unfortunately the database has not survived and was restored from around 6am today.

You will get a lot of download errors now while they were already finished.
If you have lost some credits let me know. I will try to restore as much as I can if possible.

Iam very sorry for that. Bad day ^^

Server/DB crash / Hardwarefailure
Looks like a broken RAM / hardware crashed the hole server, the downtime was 15h. I have moved the VM to my old server, this was stable but have now some errors in Linux, if you fix something another error appears. The win log still telling me broken hardware but need to take time to maybe reinstall OS, testing RAM etc.

You will now getting a lot of download errors because the input files were deleted while the WU was already finished. Around 1h after my last backup yesterday the server seems to be crashed.

Iam thinking about to let the BOINC VM on the old server, no updates (except firewall), less OS crash impacts but slower.

Apologies for the outage.

SRBase - 7 years review
The project has passed the seventh year.

Compared with last years the following process was made:

2014-2015 - 1 base solved, 314 bases unstarted
2015-2016 - 5 bases solved, 297 bases unstarted
2016-2017 - 5 bases solved, 282 bases unstarted
2017-2018 - 1 base solved, 264 bases unstarted
2018-2019 - 6 bases solved, 218 bases unstarted
2019-2020 - 4 bases solved, 120 bases unstarted
2020-2021 - 3 bases solved, 101 bases unstarted
in total - 25 bases solved, 101 bases unstarted

A last minute server crash before end of the year due a bug in the AMD Andrenaline 21.10.2 driver updated last month caused some troubles. An update to 21.12.1 was made.

There are no CRUS goals for 2022 available at the moment but will be published soon.

I will upload more work today. There are still some download errors left but fixed it with a change in max_errors_results

Back to home and the server restarted. Anyhow the AMD driver chrashed the hole system. Never had this before. Also the file system needed a repair. The backup from 10am was restored. Let me know if you have lost some work. Still having trouble and checking.

Changing of reporting primes to TOP5000
There was a change of the account SRBase from the T5k database admin. The user was changed to a project and I cant report any primes anymore. The CRUS project has now an "Anonymous" user where all the primes will be reported from now. In the description of the CRUS project SRBase is now included.

Maybe a side effect of the disabled VSS service, enabled again with 2 more changes. My ideas are at the end. 2 days in a row is bad.

The database was restored from 7am. I have no luck with this OS.

2019-2020 - 7M WUs processed, 4 bases solved, 120 bases unstarted, 23.515.051 TF WUs processed, 325627 factors found
in total - 378M WUs processed, 22 bases solved, 120 bases unstarted, 23.515.051 TF WUs processed, 325627 factors found

With the new CPU I could reduce the unstarted bases a lot.

The crashtour 2020 should be ended now, all Win10 bugs and broken hardware were fixed.

The main CRUS goal were not reached due high expectations. Lets wait for new goals 2021.

The mfaktc app on a GT3080/90 for windows is still in progress, there was an unexpected error we have not gotten to fix it yet.

A big thx for all your support to the project and a happy / in hope a better new year!

server outage / db crash again - 3rd
Every day a new repairing day. Today the power supply died on 12V, tested all components and was lucky to have a second one replaced.

Fortunately I could rescue the hole database but took some time to import (8GB). Nothing should be lost.

Maybe there are some results lost but didnt care. Will be rerun later.

If you find some errors somewhere let me know.

server outage / db crash again - 2nd
Due a win10 issue identified now, the VSS service which has restarted the PC automatically and in hope that is fixed with a MS solution found in the web the database crashed before I could do a backup. As always a good timing and sadly lost around 13h of work (results which were already done are not affected).

You will get a lot of download errors but can be ignored while they were already processed.

As always let me know how many credits you have lost and post it in the other thread.

All latest win10 updates were also installed.

Iam very sad about the current situation, it was not the first time related all biggest theads to the new OS.

No GPU work for some hosts
Yesterday I have added some new plan_class changes in the plan_class_spec.xml

There was a driver limit for different cuda versions. Now some users reported me some specs and the driver version overlapped with upcoming new cuda11 apps while they havent get any new work. Thats bad because old cards cannot running the new cuda11 apps. I need to find out another way which hosts can run which app.

server outage / db crash again
The windows update has automatically restarted the PC in the night (was disabled), the database crashed. My 2 big backups of the VM are also corrupt including the last backups of the database. Unfortunately mysqdumper cannot import the correct numbers of tables so I used phpmyadmin with success, the last backup was from 13th so we have lost 4 days (not the reported work). I had no hope to reactivate the project but I did.

Pls stop all your old WUs. I will give credit for all the lost work. If you have registered in the last 4 days and your account is not recognized pls reregister.

I must remove all the current work and recheck all bases which results are missing. Also the TF work need to be resetup (not all I think).

preparing new bases
As some of you noticed there is a very short runtime on the Riesel Base -short app. This app has a higher priority to spread out enough work for all. Iam preparing more and more new unstarted bases from 1-2.5k range which are running locally with Win64PFGW and the new base script. The range from 2.5k-10k will also be sieved on the server. Its taking too long to run it on a single core (around 3-4 month) so I let it run on BOINC. To reduce the server load all other bases are running at the same time. 24 Jun 2019, 18:05:14 UTC · Comment

prime reporting
I want to give you guys a short info about the prime reporting.

You need to pay attention on some things.

Enable email notification, thats very important that you get a message where you have found a prime to report it in 5 days. I have this short time because I must setup new work and report work to CRUS. If you cant check emails and report it in time then you can leave me a PM and I can ask Chris Caldwell to transfer the prime reported by the project to your account.

Just my 2c...

SRBase - 4 years review
The project has passed the fourth year.

Compared with last years the following process was made:

2014-2015 - 87M WUs processed, 1 base solved, 314 bases unstarted
2015-2016 - 88M WUs processed, 5 bases solved, 297 bases unstarted
2016-2017 - 99M WUs processed, 5 bases solved, 282 bases unstarted
2017-2018 - 75M WUs processed, 1 base solved, 264 bases unstarted
in total - 349M WUs processed, 12 bases solved, 264 bases unstarted

The project is now more working on a recommended bases list included by the project goals.

multiple bases went live
Due the lack of available sievefiles for the lowrunners we have started to run multiple bases with low WU amounts on different apps. The range is 100-300k for lower runtimes and 100-400k for the average apps. The runtimes are moving between 5min-2h+

To reach the mersenne goals for 2018 we are more concentrating now on the remaining bases.

Domain issues
Anyhow the connection was lost to the domain, the server was still running, I did an update for the domain / IP and all is back online. 3 May 2018, 5:44:04 UTC · Comment


apps update to v3.8.21
All apps were updated to v3.8.21

Only 2 things were fixed:

No new feature in this LLR version, but the AVX threading bug is here fixed.
This bug caused often false results after an error recovery, due to a misuse of the POSTFFT feature while calling gwstartnextft() function.

This LLR version is linked with the Version 28.14 of George Woltman's gwnum library.
The only thing new from 28.13 is better FFT selections for AMD Ryzen CPUs.


Pls note that the FLOPs are back to 0. This means inaccurate runtimes at the beginning. After some reported results the runtime will be correct again.

If you find any errors pls report them here. More work will be added soon. 22 Apr 2018, 20:31:02 UTC · Comment

SRBase - 3 years review
The project has passed the third year.

Compared with last years the following process was made:

2014-2015 - 87M WUs processed, 1 base solved, 314 bases unstarted
2015-2016 - 88M WUs processed, 5 bases solved, 297 bases unstarted
2016-2017 - 99M WUs processed, 5 bases solved, 282 bases unstarted
in total - 274M WUs processed, 11 bases solved, 282 bases unstarted

The computing power was beyond the 40TFLOP mark. KEP is still working on a more precise stats overview and will be released maybe in January 2018 so stay tuned.

The next upcoming llr app will have a new gwnum lib with full AMD Ryzen support but I dont know when it will be released.

Due the lack of available sievefiles there are some gaps in the work generation. The remaining primes for these bases are very high, the tests are going over a million. The project cannot handle so many files into one folder thats why they must be splitted into some batches.

The yoyo@home project took over the sieving part for CRUS / SRBase. More and more new sievefiles will be available in the future in a short time period. If you want to help there enable sieving in prefs.

A big thx to the Gridcoin team for the amazing computing power in the past months and of course all the other users / teams spend their power to bring the project forward.

For those who are interested in the public paper for SRBase this is now ready for download.. I will add a link on the frontpage soon. If you have any questions about it let us discuss this in the forum.

Looking forward...

There could be a short downtime to install some updates. After that I will work on the url change and do some tests. If you have still WUs in progress be hurry to send them back or cancel all.

Project update
The average app is set to beta. If you have enable "Run beta apps" in prefs disable it. This will increase all the current in progress work to have done in time. After that the url will be changed for the remaining work in the database. You must reattach to the new domain found on the frontpage. After the server cache is deleted the old url will no longer be working.

The second change is a short test after the cache is deleted.

Another plan is to add new badges for base solved and Megaprimes as requested. You can still discuss this in forum. All other badges will be get a small redesign.

If all is going as planned a lot of new work will be available soon.

webserver down
Due the high amount of new hosts attached today this killed the webserver. Nearly 300+ hosts are trying to get new apps over the slow upload connection. There was also reached the max connections to the database. I cant do anything at the moment because the bottleneck is the upload of 2Mbit. I will order 6Mbit upload next time but this will not help much.

There is no problem if all hosts have work but all at once kill every server.

Sorry for the downtime. I will try to tweaking some things but there is only a small hope to get it run better.

TOP5000 prime notification
Due to lack of responds from users I will keep you informed to check your PMs or if you have enabled the email notification your emails if you have found a TOP5000 prime. In the past I have reported most of the primes by myself because there was no reply within 1-2 weeks. Please keep your teammembers informed for the current situation. In the future the TOP5000 primes will be more and more because of the higher n ranges.

Thx for understanding!

New Megaprime found
On 24th of March, cpuid has found a megaprime 12*68^656921+1 for base S68. The prime has 1.203.815 digits. cpuid is a member of the team Seti.Germany. It was the largest prime ever found by SRBase and reduced the base to 1k.

Congratulations!

LLR Version 3.8.17 deployed
I have updated all apps to the latest version. You can find the changes here.

Please notice that the server reset the GFLOPs values to zero by every new app setup so you will have wrong estimated runtimes. This will be corrected if you have sent back some WUs.

I cannot test the app on xp64 but it should be working.

If you have any problems post it here.

New work available
I have started to creating new work. Dont hestitate to get some. 29 Jan 2016, 21:03:21 UTC · Comment


Update on Saturday, 30th (completed earlier)
If all is going as planned the update + config will take around 1h. I cant get all the WUs back in time so I will stop the server on this day. 25 Jan 2016, 20:39:25 UTC · Comment


New VM tested
With my old VM file I can only handle 32GB RAM but the software can do 64GB. I need around 45GB RAM for the current config because Iam hard on the limit. I will run out all WUs for now and change the settings after all came back.

To test the new config could take some minutes or hours. I will post some news after we have reached this stage.

base S414 solved
On 10th of January, ardo, a member of the PrimeSearchTeam found the last prime for base S414.
The prime 24*414^391179+1 has 1.023.717 digits and entered the TOP5000 in Chris Caldwell's The Largest Known Primes Database.

Nice work!

SRBase - 1 year review
The project has passed the first year and made a big jump in processing for the mersenne CRUS project.

There were 87M WUs / 273 bases crunched in different ranges. 1 of the bases was solved. 314 bases are still unstarted and will be processed by mersenne with the srbsieve /newpgen applications. All the efforts are outside of BOINC. Most of the ranges at 25k+ will be processed further in BOINC.

706,158,895,759,737
Total k's are still remaining to find a factor. It sounds big but isnt. Only 2 bases R/S280 has the most factors of all bases together. On a single CPU it will take around 250+ years to solve them but in the near future we could start some ranges on these 2 heavy weights and with BOINC and your help it will be decreasing faster as we think.

The main goal of the project is still to have around 20TFLOPs+ computing power.

The source code of the wrapper is available in the forum if you have some improvements. There is still one issue on mac and linux where I have no output in the stderr.txt file.

If you have some wishes or there is something missing in the FAQ let me know.

Whats planned in the future?
To have constantly work for one of the normal / short apps + processing all current available bases with a 200-400k range and 1 factor left.

I thank everyone who made the current success possible.

Happy crunching.

SRBase passing 1 year soon
On 27th of November the project will be passing the first year. If you want to spend some computing power or a challenge this would be great.

To get rid of the "finish file present too long" you need to install the BOINC client 7.6.6 or higher. Please also enable email notification to keep you informed if you have found a TOP5000 prime to report.

Another outage tomorrow (done)
I will try to expand the diskspace of the current VM to handle more WUs in the future. A backup is needed before I can do this. The server will be down for a short time (I hope). 31 Oct 2015, 19:14:58 UTC · Comment

the project is out of beta
After testing stuff and updates the project is out of beta now.

For all new users please create an account over the website. You will find the invitation code on frontpage and in the FAQ thread. Please take care about the weather or high temperatures to run the apps. You need a really good cooling to avoid any instable systems or producing bad results.

Its highly recommended to use the latest BOINC client 7.6.6. It has some important fixes and avoid some issues here.

If a team is planning any challenges pls let me know.

A big thx to everyone who joined the project so far.

slow work generation
The work generation started for R3 early this morning but still running after 12h. There is no work left for the other sub apps and the server is under heavy load causing clients not getting work or sporadic work for the very short R3 WUs.

To get rid of the problem in the future I need to split the WU generation for these (864000 WUs). There is no issue with a mix of some minutes WUs and the shorts but I underestimated the creation time. Iam in preparation to get out of the beta status. There are some things left before I can do this.

Iam sorry for any trouble at the moment.

mac wrapper in test
Thx to Crunch3r to made it possible. Now you can try out with Sierpinski / Riesel Base app - average2 (app 9) if you can run the checkpointing. The wrapper was compiled on Mac OS 10.8 so I hope its still compatible with your system.

Note:

Checkpoints will be written every 10min. If all is going as planned I will setup the update for all others apps too.

No space left on device (fixed)
I need to cancel around 3k WUs of the Riesel Base - short app because due the error. There are some missing md5 files which are needed for download and will run into an error soon.

You will find the statement and the source code here and for the latest llr app here

For compiling, you need to replace the gwnum lib with the one in the first link and change the string 28.5 in the lmenu.c and Llr.h file to 28.6.

server problems (fixed)

First megaprime discovered
On 20th february, vaughan has found a megaprime 29*920^367810-1 for base R920. The prime has 1.090.113 digits and entered rank 87. The WU was running on a Xeon(R) CPU E5-2650 v3 @ 2.30GHz on linux and took 90515.704 sec. Vaughan is a member of the team AMD users. It was the second prime found by him and decreased the base from 5 to 3k. Congratulations! 1 Mar 2015, 10:32:39 UTC · Comment

No space left on device – running out of Inodes
Yesterday the server reached the Inodes limit. There was enough space left but with all these small input files the Inodes ran out of space. New WUs cant create at the moment. I could try to move the BOINC folder to another bigger virtual disk or I will cleanup the download folder soon. 3 Feb 2015, 6:06:21 UTC · Comment

releasing primes
I will only posting primes on bases <70k left. Its too much effort to find out who has found one. Notice: all primes after 200k runs could be a TOP5000 prime. To get more famous than how much primes you have found is to solve a base or get a TOP5000 prime. 27 Jan 2015, 16:46:08 UTC · Comment

unexpected downtime
Iam using the latest fritzbox and every night there is a restart of the box. The problem is known by my provider and the box is still in development. They even switched it from IP4 to IP6 last night. I called a staff and he has rechanged IP4 again - for now..

In the next days until end of January it can happen again. The deadline for future WUs are longer now to not loose any credits after the deadline. I will try to change the deadline for all current WUs to give credits for them.

I apologise for any trouble.

max success results
I will change the value to 2 for the next WUs. All results which are over the deadline should get credits too and not invalid. 4 Jan 2015, 9:26:18 UTC · Comment


Decreasing deadlines
Many WUs are running into timeout and it will take very long to get them back if they will be sent out again and again. If your host cant finish a WU in time like the long runners pls disable the app in your preferences. The main reason is that I cant add new work until all files are returned. This wastes a lot of time time. I will decrease all deadlines for new WUs. 3 Jan 2015, 18:08:24 UTC · Comment

New tests for linux soon (started)
The internal test of the linux64 was successful. The zip compression of the llr app has still the execute bit so I dont need the copy_file tag anymore. The text file busy error could be fixed now but need some tests first for linux32 and linux64. If all is going well and the OSX app has the same issue I will change it too. 23 Dec 2014, 10:06:58 UTC · Comment

cable provider interruptions
Not the first time. The internet get interruptions every minute. I dont know how long this will take to fix.

If you can read this I have had a chance to write that but you are informed.

Sorry for the troubles. Its Christmas time or in inet words downtime :/

400 test WUs for all apps loaded
I need to check if some of the errors are gone from linux and win32, OSX is new, also its needed to compare the residues from all apps. The runtime is around 4s per WU.

double checking tests on weekend
for all apps. Its planned to set the deadline to 1 day for new bases and quorum 1. The residues will be saved for later DC.

double checking
At the current config on server a double check is not possible with the current validator. I need to rerun a complete base with quorum 1 to compare both results in excel. Its the same as running quorum 2 but takes a little more effort to the end result.

GLIBC_2.14 not found error
Should also be fixed with a new recompiled linux wrapper. glibc2.11+ is required then. Thx to deletenull for the new wrapper files!

couldn't start app: CreateProcess() failed
The error should be fixed in the next apps release for WinXP. The boinc wrapper wasnt xp compatible.

OSX test WUs are available (delayed)
pls report any problems. At the current time its the standard BOINC wrapper and no checkpoints are working.

I have delayed it, it seems nobody has a MAC.

OSX tests later today
For all MAC users, hello zombie67 ;) I will add a 32/64 bit version later today.

Iam looking for someone who can compile the mac wrappers 32/64bit and linux wrappers 32/64bit (on ubuntu 10.04 with glibc2.10 support or similar OS). Send me a PM if you are willing to help here, I will send you the source code.

New tests soon
I will add some more tests soon for win32 and linux. Also a quorum 2 will be setup with bitwise validator and homogeneous redundancy. Its needed to double check the residues of output files to make sure nothing is bad.

Base R920 loaded
There are now fixed credits for the following steps:

n=50-60k -->4cr
n=70-80k -->9cr
n=90-100k -->13cr

based on an AVX CPU. The runtime is around 2-7min. 1 prime was found on base R784 (up to n=200k)

Sending out test WUs for linux 32/64 bit
There are now some test WUs for linux32/64. The tests take only some seconds. Pls report any problems.

New apps are prepared
for linux32/64 and win32. If the rest of the WUs are done the next test with some smaller numbers (around 2-3s per test) will be setup. I have also removed the compression of output files.

The Riesel Base R920 is reserved with 7244 WUs with a runtime of 2-7min (AVX) per WU.

Next plans
After the rest of the WUs are finished I will add some tests for linux32/64 and windows 32bit with double checking (quorum 2). If I find a way with help from primegrid I could change the validation process.

The project is now beta
1114 results back with success
14 results back with an exec_dir error but from the same user

First test started with base R784
The runtime is around 10min on a i7-4930k @4Ghz with AVX. Checkpoints are every 10min. Credits are FLOP count at the moment. The project is still alpha.
