Poor FAH Client Performance on Linux Desktop

Posted: Sat Jun 29, 2019 4:25 pm
by Planorez
I am running the Debian Client on a Linux Lite 4.4 Desktop with very poor performance. The processor is an AMD A4-5400 and to not use the GPU I run a NVIDIA video card. I get 100 PPD out of this PC where with the Google Client, I was getting 2000-2500 PPD. Can anyone explain the dramatic performance hit?
Thanks,
Planorez

Welcome to the folding support forum.

Please post the beginning section of your log file to give us information about your system and its configuration. Directions on how to locate and post the log are included in the Welcome topic - viewtopic.php?f=61&t=26036, for Linux that would be this post - viewtopic.php?p=261083&f=24#p261083.

Most common reasons for a low reported PPD are failure to enter your passkey or not waiting long enough. The client needs to process a few percent of a WU from a project it has not done before to get an accurate estimate for PPD, ETA and TPF (time per frame).

One note - the PPD estimate that the NaCl client for Chrome gave was off, there was a bug that caused it to give inaccurate estimates of the PPD that would be earned.

The NaCl client was, in fact, very simiar to the CPU client running FAHCore_a4 on your CPU. If you enable your CPU slot, it should get a similar PPD to what the NaCl client actually gave you.

For help with your GPU slot, follow Joe_H's instructions.

The NaCl client has been running extremely low PPD as well, before it was shut down.
A Core i5, 6 core, 3,9Ghz got 66k PPD in control, ended up getting barely over 2k PPD in NaCl.
Something got messed up there, I guess...

Did you use a passkey on your desktop client ?

Sometimes, the first CPU WU on desktop client is run with only one CPU core ... after configuring the client, the next WU should use all available cores and show better performance.

It is a dual core CPU, if he is using a graphics card, one CPU is dedicated to that, so all his WUs will be single core with a GPU.

Currently cpu:2 and -np 2 so it is trying to use both cores.

I just saw his configuration, he does not have a passcode installed.

No Graphic Driver seems to be installed from either AMD or Nvidia. F@H needs the vendor drivers.

(The AMD driver would not be enough to allow that old GPU to fold) We can not see the Nvidia card to even guess how productive it might be.

Using a bonus point calculator, this WU would get ~2800 PPD with a passkey. That would be after completing 10 WU's with a passkey. The PPD without a passkey is about 800.

For comparison purposes, the actually PPD for the NaCl client after correcting for the bug I mentioned previously would have been about 7-800.

As your CPU is based on a "dual" core Piledriver architecture which shares a single FPU between the two "cores", you might get better throughput using only one core. You would have to test that to see which way processes WU's faster.

The FAQ's for points and the passkey are here - https://foldingathome.org/support/faq/points/ and here - https://foldingathome.org/support/faq/points/passkey/. The second includes a link for obtaining a passkey.

The error, here, is you assumption that a single/dual CPU can get more points than it can. With the completion of 10 WUs using a passkey, your PPD will certainly increase, but not to the levels you're probably expecting. You're actually completing only a small amount of processing to science.

I reequested and installed a passkey. The PPD went from 670 to 2800. Why does installing a key cause that kind of difference?

PPD does vary with the particular WU assigned and STRONGLY with how long it takes you to complete the WU in comparison to how long others take to complete a similar WU. (Shutting down your computer overnight is disastrous unless you FINISH the WU(s) being processed. A few minutes to reboot would only make a small change.)

There was a time when the quick return bonus made sense.
But with the advances in hardware speed, most people make most points via the quick return bonus, and not the actual work.
There are WUs I run, that get nearly 10x the regular PPD in quick return bonus.
All times are UTC
