Need help with setup

[Otis11]

Yeah, NVIDIA is the way to go for F@H or GPUGrid... Not sure how they compare over on Milky-way or Collatz though...

1) In order to get more WUs you can: reboot, restart boinc<--if that doesn't work, then Detach/Re-attach should work. No reason to wait the 24 hrs.

Well BOINC recognizes 4 gpus on the messages tab, but will only run 3. At points it runs 4 for a couple seconds and then quits. Also looks like something is throttling the gpus they are only loading at 70-75%???

2) create a file in notepad and name it: cc_config.xml , then copy and paste the below into it. It goes into your BOINC folder. Not sure what OS you are running, but in Vista/win7 it's inside programdata folder:

- <cc_config>
- <options>
<ncpus>8</ncpus>
<use_all_gpus>2</use_all_gpus>
<report_results_immediately>1</report_results_immediately>
</options>
</cc_config>

report results immediately can stay at 1.
use all gpus can be any number from what I understand.
ncpus is the difficult one: Try totaling up your cpu cores + your gpus and enter that number, then see how many WUs total are runnning, then increase/decrease that number until the total running WUs = cores + gpus.
You will need to completely restart Boinc each time, including shutting down "boinctray.exe" via task manager. Instead you can try the Advanced>Read config file.


3) Check Advanced> Preferences:

Tried you advice naja even if I detach the project or try anything else I still can get new WU's still having the commo deferred message. Tried setting ncpus to 12 and all it did was enable 12 wu's for the cpu.

If you haven't already: Detach, reboot, then re-attach....

Strange, I've never had it behave that way...... You can try adjusting the use gpus number, but my understanding is
that the number is irrelevant and can be any number....

This machine is about ready to get booted out the window

[Naja002]

Been there....

What version of boinc are you running?

[=[PULSAR]=]

6.10.18 I was thinking about trying the beta see if that helps at all.

[Naja002]

It should work. You can try 6.10.29 it works well, but I don't think it's going to fix the issue(s).....

[=[PULSAR]=]

Trying 6.10.35, gpugrid is still making me wait and WCG is currently down. Glad I found 64-bit though I've heard its suppose to have a 10% increase.

[123bob]

Yes, WCG uploads of finished WUs is borked at the time I right this.

Confirm that a 64 bit BOINC on a 64 bit op sys gives about a 10% boost on WCG, for sure.

As to getting your total GPUs running on Grid, IDK, but it looks like your in good hands now.

just some comments on the cc-config file:

do not use the ncpu option. this is for debugging only and will mess with your system. (link)
This setting is for CPU usage only and won't have any effect on GPU WUs

<ncpus>
Act as if there were N CPUs: run N tasks at once. This is for debugging, i.e. to simulate 2 CPUs on a machine that has only 1. Don't use it to limit the number of CPUs used by BOINC; use general preferences instead.

For use with CUDA: When you want to do CUDA only, not use the CPUs at all, set <ncpus>0</ncpus>
If you want to use all CPUs, either omit using this option, or set <ncpus>-1</ncpus>

set <use_all_gpus> to 1 - this setting has only 0 or 1 (2 might work, but to be sure I'd use 1)

[Naja002]

On Gpugrid ncpus was needed in the past. Then they did away with it. Then I found a few months later that things were not right. I tried the ncpus = cores + gpus and found that I had 1 too many WUs running. So, I started subtracting 1 (from the total cores + gpus) and it has worked fine across various setups and Vista. Now with Win 7...it's apparently not needed again. Seems to be running as it's supposed to in 6.10.19 and 6.10.29.

At times in the past I have come up short on WUs v cores + gpus....If everything else is in order, like gpus recognized, then I've used ncpus to make the final adjustment...

[=[PULSAR]=]

Okay cpus have been crunching how long do results usually take to post on gpugrid and wcg?

[Otis11]

GPUGrid you should get results either tonight or early tomorrow with full strength in 2-3 days...

WCG, because of validations, will take atleast 5-6 days to reach full strength, but you should see atleast some result in a day or two.

and glad you got it working!

[=[PULSAR]=]

Okay well testing out the new beta and well still same issues only folding on 3 gpus Oh well I'll let it go for a couple days before I tear it down and start another build.

[CaptMorgan]

and Thank you =[PULSAR]=

The 1 not recognized is still your main monitor display? Gpu 0?

Did you check your preferences as above?
