AMD EPYC 2x 7551 on a SM H11DSi

Postby thorsam » Mon Jul 30, 2018 3:19 pm

Is V7.5.1 ready for a dual AMD EPYC system?
It seems that the software only find one of the cpu?

Code: Select all

Re: AMD EPYC 2x 7551 on a SM H11DSi

Postby bruce » Mon Jul 30, 2018 3:41 pm

The CPU that FAH has identified has 32 threads. One CPU thread is allocated to process data for you GPU. Large prime numbers of threads (like 31) are prohibited, so you see
14:49:09:WARNING:WU00:FS00:AS lowered CPUs from 31 to 30
In this case, Project: 14050 is initially allocated 30 threads.

When you reconfigured to have two CPU slots, it looks like the system reallocated it to two slots using 15 threads + 15 threads. A new WU was downloaded from Project: 14049 to use 15 threads.

The atom-count of most active FAH projects is somewhat limited so there may be times when you have trouble finding individual projects that can successfully keep almost all of the CPU threads busy. Most donors with large CPU counts tend to split up their system into multiple CPU slots. I recommend you change the number of allocated threads from -1 (system choice) to other values that seem to work well for you.

Your GeForce GT 710 LP GPU is really very weak and won't earn a lot of points. Yes, it will work but it may not be the best choice. I had one for a while and replaced it with a GTX1050 LP because I had room for the dual-slot GPU, though that added a lot of heat to that system. I do still have a system with a GT710 because the PCIe slot configuration doesn't have enough room for the double-wide GPU.

Are you setting up two CPU slots of 16 CPUs each? (I almost think you set up two but left them at -1 and F@H is confused)

If two at 16 CPUS is still ugly, try 2 at 12 CPUs and 1 at 8 CPUs.

His motherboard has two AMD EPYC 7551 CPUs ... so the client should see 128 CPUs (2*32 cores with HT) and not 32 ...

Just to be sure, does Windows see all the threads ?

I have not been able to find it on-line, but in the days of Windows 7, Windows Server was required to support multi-sockets hardware. That might or might not include Win10 Enterprise.
I notice that the OS version detected is 6.2, not 10. That's strange.

What does the Performance tab of Task_Manager report or CPU-Z?

(MS Doesn't make it easy to find their multi-socket support limitations.)

First, sorry for my delay and thank you for your response.
I'm fighting with a pipe burst in my flat, and with Supermicro, because it's seems that the BIOS has a bug.

The entry in the tab 'Slots' is, was the software has even done.
Task_Manager and CPU-Z reportet correct 2 CPUs each with 32 cores respectively 64 threads.
The sense of my Geforce GT 710 is only, to have a better solution then 1024x768.

At the moment i'm install Linux Mint 19. I guess, this will be much better.
With my Windows_Installation the boinc_software use 128 threads.

I give you response, quick as i could.

Re: AMD EPYC 2x 7551 on a SM H11DSi

I suspect that F@H will not use all 128 threads in one slot.

I think that you might try 4 slots of 32 'CPUs', and if that does not find work, 8 slots of 16 'CPUs'

Your GT710 is a very low end Kepler GPU; Kepler is still supported. I would not worry about folding on it.

I've opened a bug report on this issue:

By the way, I suggest you remove the GPU slot in FAH's configuration. Inasmuch as you don't plan to fold on your GPU, this should reconfigure your system for 32 threads rather than 30. It's not much, but why not?

When you examine which CPUs are busy in Task_Manager, does it show all of the processing being done by one CPU at almost 100% or does it show the work distributed across all of the CPUs at about 50% each?

F@H used to scale to 128 threads, i believe they have tested recently upto 96 threads. Mint will be a better bet than windows, if you get it working please post some results, i'm very interested.
