Hello All!
What is the best "Bang for your Buck" in terms of CPU's for Prime crunchiness?
Is AVX-512 worth the extra heat considerations?
Or would it be better to go with less heat intensive options?
More cores vs more GHz?
I have questions! Please provide answers!

A CPU with large cache 64MB+ (Ryzen 7950X+) for multicore would be fine, AVX512 vs AVX2 is not worth it, you need to collect some datas from different CPUs and see whats the best. |

Thanks! I will keep that in mind for my next machine replacement.
Does having a large cache increase heat generation?

no, I will pickup some datas from DB to have a comparison. |

Thanks!
GenuineIntel Intel(R) Xeon(R) CPU E5-2698 v3 was my latest buy!
Good to know those stats are accurate!

Which MB did you buy or did you buy a pre-built system?
I too have been looking at these cpu's for my next build.
ALSO have you had a chance to run a some tasks yet? |

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.

I LIKE that place thank you very much!! I LOVE that their prices include shipping!!
I test built a pc with dual Intel Xeon E5-2697 12/24 core cpu's, 128gb of ram, 250gb SSD, a generic 128mb gpu and an 850 watt psu for $310!! I think I could run SRBase out of tasks pretty quickly with one of those, or at least keep Rebirther on his toes!! |

I wanted to give an update...I bought a dual Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz [Family 6 Model 62 Stepping 4] with 10/20 cpu cores on each cpu, so 40 cpu cores in the pc for $280 SHIPPED!!!
THANK YOU VERY MUCH for telling me about the place!! No it isn't the fastest pc but it sure does churn out 39 cpu tasks and 1 gpu task at a time!!! It's currently doing the SRB Long tasks like this on average:
25 Feb 2024, 20:30:53 UTC Completed and validated 156,990.60 156,990.60 2,800.00 Sierpinski / Riesel Base - long v0.42 |

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!!

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? |

Thank you very much!! My current goal is to get each app up to 100K hours, the Long tasks got there today so I'm moving my pc's to a different Project, I still have them trying to get tasks here just not the Long tasks anymore. I did increase the number of gpu's to get the TF tasks though as I have a LONG way to go to get to 100K hours in them. |
