Kitties do PG.........

Not the same as Seti.....but it does keep the GPUs warm.
And the kitties do like to be warm and cuddly.

Snappy little WUs......I like that.

Welcome (back) to PG ...
It depends on the subproject -- SOB can run for weeks! Many subs to choose from, some run in minutes, most many hours or days. Look into the Badges for accomplishments.

Well, nothing like that here so far.
Kinda curious why it only runs 2 CPU tasks instead of 4 alongside the GPU tasks.
Normal?
Any opti apps here? Or just stock...?

Apart from some fiddling to work around boinc client bugs for Fermi cards (or to get PPS Sieve for ATI), pretty much all the apps are already optimised, or will be as soon as the current batches of work dry out.

As to why you're only getting 2 CPU WUs rather than 4 - no that's not normal - so I'd advise you check your client settings.

Got tons of free disk.
Memory set to 100% usage.

Seti is the only other project loaded, and of course, they have no work available right now, so PG is the only thing running.

I have a similar problem with a Pent D 830 only running on one core with both GPUs crunching. I wonder if this is a more general BOINC issue of having a matching number of GPUs to CPU cores (i.e., your 4 GTX 295's would match the 8 cores in the i7). What happens if you disable one of the GPUs?

IIRC, the pps-cuda-application itself reserves 0.55 cores of a cpu. Take a look in your "client_state.xml".

Normal?



Try removing the <ncpus> tags completely, and then restart BOINC. This isn't really intended for users to limit the number of cores being used; it was written to allow the developers to test the scheduler code for more CPUs than they actually had to test with.

Since it's a debugging tool, it's likely it's not as well tested as stuff that's intended for user control. It's possible it's causing some weird and unexpected behavior.

Although using a percentage is definitely strange, the "use at most XXX% of the processors" entry in the preferences dialog is the intended way of controlling how many cores BOINC uses.

Honestly, I don't think this is your problem, but you've tried all the other obvious stuff, so you might as well give this one a shot.

Got rid of the ncpus......
Still no dice. Only runs 2 CPU tasks, and task manager shows about 49% system idle usage. 2 cores are going to waste, and I am at a loss.
Boinc recognizes 4 cores in the startup messages.

This was never an issue while running Seti. Nothing in the setup was changed.

Got rid of the ncpus......
Still no dice. Only runs 2 CPU tasks, and task manager shows about 49% system idle usage. 2 cores are going to waste, and I am at a loss.
Boinc recognizes 4 cores in the startup messages.

This was never an issue while running Seti. Nothing in the setup was changed.


If you turn off the GPU, do all four CPU cores get used?

IIRC, the pps-cuda-application itself reserves 0.55 cores of a cpu. Take a look in your "client_state.xml".


That's it!

Fixed it by editing the value (mine was at 0.57, reduced to 0.47 and both CPU cores are crunching as well as both GPUs).

Find your client_state.xml file in the BOINC directory (this location is different depending on your OS, but will always require that you view hidden files). In your case with Win XP, it should be under:

C:\Documents and Settings\All Users\ Application Data\BOINC

Make sure that BOINC applications are not running, then edit the client_state.xml file in Wordpad or something similar. You are looking for the lines for the pps_sr2sieve application that read:

<avg_ncpus>some numeric value here</avg_ncpus> <max_ncpus>some numeric value here</max_ncpus>


change the numeric value in the middle of these two statements as needed. For my dual core/dual GPU systems, that meant reducing the value such that doubling it is less than 1 cpu (i.e., less than one full core). On multi-core/multi-GPU systems, you will need to adjust the value to see what runs well/stably (i.e., with 4 GPU you may not be able to reduce the value enough to free up all cores, but you should certainly be able to get most of them back to crunching).

Well......sounds like this is not going to be easily solved.
The edit bit is not going to be practical if it is reset when getting new work.

Just have to let it plod along as is. Odd though that some others do not seem to have the problem.

Use an app_info file to set your own value for the cpu usage. 1% should work fine. (Someone else will need to point you to a working app_info template for all the subprojects; I haven't yet needed to use one here.)

Big disadvantage is you have to set this up for every PrimeGrid subproject you want to run, and you need to update it every time they update an app that changes the files needed to run the app. At PrimeGrid, that's pretty often. PrimeGrid is a fun project, but if you go the app_info route, you need to stay on top of things. Fortuntely, although we've got an active user community here, it's nowhere near as large as, say SETI, so it is possible to keep on top of the boards without spending 5 hours a day reading them.

I can't help but think there's a server side setting that can fix this, but this is BOINC, and such assumptions are often both naive and false.

Use an app_info file to set your own value for the cpu usage. 1% should work fine. (Someone else will need to point you to a working app_info template for all the subprojects; I haven't yet needed to use one here.)

Big disadvantage is you have to set this up for every PrimeGrid subproject you want to run, and you need to update it every time they update an app that changes the files needed to run the app. At PrimeGrid, that's pretty often. PrimeGrid is a fun project, but if you go the app_info route, you need to stay on top of things. Fortuntely, although we've got an active user community here, it's nowhere near as large as, say SETI, so it is possible to keep on top of the boards without spending 5 hours a day reading them.

I can't help but think there's a server side setting that can fix this, but this is BOINC, and such assumptions are often both naive and false.

In thread App_info file have i done this for linux64 and every subproject.

Well...
Just to confirm our suspicions....it is the .64 CPUs in the GPU tasks that is causing my problem.

PG is a bit slow in handing out GPU work right now, and I just crunched out my GPU cache.

When I got down to 2 GPU tasks left running, a 3rd CPU task finally started running.
When I got down to 1 GPU task left running, the 4th core fired up.

So if the project could amend the amount of CPU used by the GPU tasks to something less than perhaps .45 or so, many hosts might be more productive without manual intervention and manipulating of ever changing app_info files.

EDIT...
And, as if just to prove my point, whilst I was typing the above post, I got 5 GPU WUs, and when the GPUs went back to work, Boinc paused 2 of the CPU tasks and is back to idling 2 cores of the CPU.
