SLI GTX 460: Low PPD? - Page 3

post #21 of 27
Thread Starter 
Okay, it's now doing two separate work units and both GPUs are loaded; The difference in timesteps for the log files is the same, you were right, the viewer has no idea what the correct ns/day readings are. I'm not sure what the other GPU was doing when it was also loaded before (the same simulation?)

In any case they're both chugging along at a cool 60C and 22.5k PPD

HFM calculates by the TPF in your logs, not the ns/day.
This is what it looks for, then it gives you the numbers you see.
Code:
[21:07:51] Completed    500000 out of 50000000 steps (1%).
[21:09:03] Completed   1000000 out of 50000000 steps (2%).
[21:10:15] Completed   1500000 out of 50000000 steps (3%).
I really have no idea why it was getting usage before, but that is one of the rare buggy occurrence when having SLI enabled.



Now that you got that fixed, what is the PPD your CPU is getting?
Cause earlier it was very low and using the unicore unit, where you able to get that fixed?

Yeah, I was going off those values the second time, for whatever reason with SLI enabled the second GPU was running but apparently not doing anything when I was running two copies of the same client.

The SMP client is still using B4 core (single threaded) so if I want it to use multiple cores I'd have to spawn 5 more copies of it using new directories if I wanted it to use all the cores.

Code:
[22:17:03] + Processing work unit
[22:17:03] Work type b4 not eligible for variable processors
[22:17:03] Core required: FahCore_b4.exe
[22:17:03] Core found.

No you do not need to spawn 5 more clients.

Just need to add the -smp flag.
How to add flags

Then go to your work folder and delete the contents and restart the client.
After that everything should be set up right and you are folding a multi core unit (SMP).

Ok...! CPU now at 100% with GRO-A3 core running a 2ns simulation. No idea on PPD, still doing the first unit

edit: PPD is about 4.5k on the cpu

there's no way your getting 22k ppd per gpu...
maybe combined yes...
