Should we expect a zero recent average credit?

I would think a restart would not be unexpected...

I hope all is well Reb!

I am almost out of CPU workunits as well.

Looks like all of the new uploaded work units got claimed right away. LOL.

Glad to hear I helped you!

I use to give each core a task, but I found that giving larger tasks more cores really helped with completing them in a timely fashion.

You can find information on how to do that with this post: https://srbase.my-firewall.org/sr5/forum_thread.php?id=6&postid=3795#3795

You can choose to give each workunit app a different value of cores to use and concurrent tasks to run.

I ended up giving all tasks 4 cores and limited the concurrent instances to (Number of cores/4)-1 so that the TF task would run on the GPU.


I do know about that but do you know about wuprop? wuprop.boinc-af.org/ is a boinc project that you one task per pc and it counts the hours you put in for each application at each boinc project, ie these are my SRBase hours since I started running it counting my SRBase hours:
SRBase Sierpinski / Riesel Base - long 92,062.18 215.62
SRBase Sierpinski / Riesel Base 60,467.38 0.00
SRBase TF 57,775.23 5.95
SRBase Riesel Base - short 55,398.58 0.00
SRBase Sierpinski / Riesel Base - long3 54,583.10 0.00
SRBase Sierpinski Base - short 52,399.33 0.00
SRBase Sierpinski / Riesel Base - long2 52,092.23 0.00
SRBase Sierpinski / Riesel Base - average2 51,083.50 0.00
SRBase Sierpinski Base 50,964.62 0.00
SRBase Riesel Base 50,888.92 0.00
SRBase Sierpinski / Riesel Base - average 50,772.85 0.00
SRBase Sierpinski / Riesel Base - short 43,424.43 0.00
SRBase Sierpinski / Riesel Base - average3 38,794.68 0.00

You can see the app and after that is my total number of hours in each app and the last numbers are the number of hours for the last 24 hours.

I will also let my signature come thru this time so if you have them turned off turn them on so you can see the total number of credits I have right now and why getting credits faster isn't my goal anymore. And YES that is REALLY 1.6 Trillion credits!!

mikey


That is a pretty neat project. Thanks for sharing!

That is impressive amount of time on SRbase and the 1.3 Billion in credits is not bad either! :)

What is your current goal?

2 hits in nearly one week... Insane luck!

Nexhr, a member of the team Gridcoin found a megaprime for base S778.
The prime 163*778^424575+1 has 1.227.440 digits and entered the TOP5000 Largest Known Primes Database..

Oliver Kruse found a megaprime for base S730.
The prime 84*730^560037+1 has 1.603.569 digits and entered the TOP5000 Largest Known Primes Database.


WOOO!

Congratulations both!

What is CRUS, where do I create the account and do I create the name Dingo in my case. For us that have no interaction with CRUS or the TOP5000 Primes except for Primegrid doing it for us.


CRUS stands for "Conjectures R' Us". It is the project that helped(?) start SRBase.

The coolest thing about SRBase is that if you find a prime.

You get to claim it!

I have found two so far! (check Signature)

It made my month each time!

It does take a bit of trying to figure out the reporting, even with the instructions, but it is worth it.

Best place to start is here: https://www.mersenneforum.org/index.php

Make an account and post questions - someone will answer you.

What Rebirther is talking about is instead of using the LLR tag when reporting you would use the PRST tag - this gives credit to those who helped (you) find the Prime(!).

It seems to be 3 orders more, no? :)

Thats correct, changed the title.


Thanks for correcting!

I bought a pre-built refurbished HP Z840 dual socket from a reseller.

Yes! It has been up and running for ~8 months now and has gotten ~63M credits.

A lot of the credits were from TF, but it definitely does CPU tasks well with dual E5-2698 v3 16-core CPUs.


You are doing GREAT with it!! Was it a local to you supplier or not? Either way can I have their name so I can check them out please? I am always looking for newer pc's to increase my crunching with less power than I am using now. I'm still using some older AMD 6 cores and some Intel I7-4??? series cpu's. I do have a few newer ones as well like an AMD Ryzen 9 5950X 16/32 core pc but the older Intel Xeon pc's I have do need to be replaced with pc's with more cpu cores.


I wish it was a local supplier! I would definitely visit to pick it up directly.

Absolutely! The vendor is https://pcserverandparts.com/.

The only downside I have seen so far is they don't have a lot of post-commercial use Ryzens yet.

15) Message boards : Number crunching : Deadline change on S79? (Message 9415)
Posted 26 Dec 2023 by Profile Prescott


I have been experiencing ~10% work unit attrition with the new deadline.



Is there any kind of penalty I'm not seeing? The ones lost due to this generally disappear within a few days as Rebirther purges the database


No penalty, that was just the percentage of works units lost to error "Not started by deadline" over work units completed between database purges.

Looks like Rebirther found and fixed the error.

I have this problem since I turn off my machines for ~7 hours to avoid very punitive peak time electricity pricing.

I have been experiencing ~10% work unit attrition with the new deadline.

I do know the inefficiency is because of the 2023 Goal...

Rebirther has promised a return to the norm.

I am not concerned.

Why can't I get these unsent WU ?


I have stopped sending them for a while because of S79.


Are you able to say "Do not send these work units until these other work units are finished"?
