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. 14 Sep 2023, 11:49:33 UTC · Comment

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 12 Jun 2023, 10:35:56 UTC · Comment

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.

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The llr application has been replaced by the llr2, less work and no unnecessary doublechecks but with less performance.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.

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.

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. 16 Oct 2022, 11:52:08 UTC · Comment

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.

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. 15 Jan 2022, 12:49:03 UTC · Comment

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.

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.

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.

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. 23 Sep 2018, 9:35:07 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.

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.

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.

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.

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

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. 14 Feb 2016, 16:41:11 UTC · Comment

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. 18 Jan 2016, 21:51:29 UTC · Comment

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! 13 Jan 2016, 19:06:21 UTC · Comment

base R492 solved
On 18th of December, Mumps [MM], a member of Team Seti.USA found the last prime for base R492.
The prime 81*492^399095-1 has 1.074.352 digits and entered the TOP5000 in Chris Caldwell's The Largest Known Primes Database. This is also the second Megaprime.

Well done! 21 Dec 2015, 18:16:23 UTC · Comment

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. 27 Nov 2015, 17:10:27 UTC · Comment

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. 6 Nov 2015, 19:19:24 UTC · Comment

Another outage tomorrow (done)

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. 12 Aug 2015, 18:33:29 UTC · Comment

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. 7 Aug 2015, 20:29:57 UTC · Comment

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. 28 Jun 2015, 18:11:34 UTC · Comment

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. 5 Apr 2015, 20:46:38 UTC · Comment

server problems (fixed)
If you have noticed the website is very slow at the moment because the server reached the max_connections and the database was growing up too fast.

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.

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. 6 Jan 2015, 17:16:26 UTC · Comment

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 fritzbox arrived
I need to configure the box and test it for a hour so the server is down for a while.

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 :/

OSX test WUs are available
Pls attach some MACs as soon as possible for testing both apps 32/64bit.

-Reb 12 Dec 2014, 18:34:18 UTC · Comment

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.

S887 results
Sadly, nothing was found up to n=200k.

-Reb 12 Dec 2014, 15:49:24 UTC · Comment

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.

-Reb 11 Dec 2014, 17:11:57 UTC · Comment

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.

-Reb 7 Dec 2014, 16:20:18 UTC · Comment

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.

Base R920 results
The base was finished up to n=100k, 1k (94*920^64819-1) was eliminated by JayPi. Congratulation!

-Reb 7 Dec 2014, 9:34:04 UTC · Comment

HRtest WUs now available
to test quorum 2 and homogeneous redundancy 2.

-Reb 7 Dec 2014, 9:31:13 UTC · Comment

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.

-Reb 2 Dec 2014, 17:29:09 UTC · Comment

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.

-Reb 30 Nov 2014, 17:09:59 UTC · Comment

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.
