I have been running PrimeGrid on one host for the past few days. I have this host running PrimeGrid via two GPUs.

Should be fun, I'm looking at completing 8 cpu units a day and about 72 gpu units a day for about 180k a day.... I doubt thats good enough for a decent individual finish, but with only a few members together, it makes a decent team finish based on last year's results....

If we're in a solid spot in the WCG Christmas Challenge, I will switch over a rig or two for this. You'll have to tell us how to configure things so we are doing the "right" type of work.

PrimeGrid has quite a few different applications. Here is a listing: http://www.primegrid.com/apps.php Enabling specific projects can be done via Your account -> PrimeGrid Preferences -> Edit PrimeGrid Preferences. Since I'm running other projects like WCG via the CPU, I choose to enable only the CUDA projects. I set Use CPU to No and Use NVIDIA GPU to Yes. Then I selected the CUDA projects in the project list. Depending on whether you are running primarily CPUs or GPUs, you can select applications accordingly. I believe this particular contest is for Proth Prime Search (Sieve). PPS Sieve has applications for CPU, CUDA, and ATI and there are checkboxes to enable each one of those.

It's basically as easy as setting your applications in wcg.... Pretty much every project that has more than one application is set the same way.... Wcg is pretty much the only project I've seen that doesn't follow the same site template.... But all of the functionality as far as I have seen I'd there....

I have a Linux system with a GTX 295 that I can switch to PrimeGrid when the challenge starts. It is currently running dnetc. I'm not sure how well it will perform with PrimeGrid though. The Fermi's seem to do really well but I'm not sure on the older generation.

I don't remember.... Most of my PrimeGrid points came from my 295.... But it is also what killed my 295.... Or it was bad to begin with and me setting the fan to 100% was too much for it.... It would be awesome if there was an out-of-warranty repair service for it, baking it cleared up the artifacting on it but it won't fold or crunch and only one gpu can be enabled or it bsod's.... Tracker doesn't recognize it but the other folding programs do.... If baking didn't mess up the serial number stickers evga would have did an out of warranty rma thing for me considering why I couldn't register in time to get the lifetime warranty on it....

I'll try to get a "guide" posted on setting this up for the contest in the next day or so for those who need it.... Last I checked they still didn't make the forum post announcement for it....
In general, only tasks assigned after the challenge starts count.... I don't know how the scoring system will work since the sieves don't appear to find primes, they seem more to eliminate primes by finding factors....
I plan to run 8 threads and my 460 on this, might have to cut back the threads because this runs hot.... 8 threads for wcg and tthrottle rarely throttles down, but it does with 7 wcg and 1 primegrid....
I'm waiting on the official announcement to post because it should list scoring information and a guide on how to handle the start of the challenge as far if you have a farm or not and whether you'll be able to monitor and access them at the start and the size of the farm.... If this this and this then allow new tasks at the beginning, if this this and that then don't do a thing.... There shoul also be instructions as far as towards the end of the contest and aborting early or trying to squeeze in a task before the final deadline of it but Im sure that is more of an issue with the larger and slower task challenges....

You mentioned in another thread a project where you got the same points for 20 hours of CPU work as you did for 20 minutes of GPU work. Was that this particular one? If so it seems that we should be focusing on getting GPUs but not necessarily CPUs.

Yes, it's the same one.... I'll see how mine handles 8 threads 24/7 and decide from there if I run my CPU for it but I'll probably end up going with CPU for wcg to finish strong and the gpu on primegrid.... Running 4 threads primegrid and 4 wcg, it throttles down from 80% to about 60%....

http://www.primegrid.com/forum_thread.php?id=3812#44436I have some more to look into, only enabled the nvidia gpu tasks for pps and it enables the 2 shortest CPU applications, it doesn't when both CPU and gpu tasks for pps are enabled.... I guess it's always possible to have it pps only and just suspend the CPU tasks and resume them after the contest, but I think that is one of the "no no's" forthe contest as if others get that task during the contest, they won't get their points until your task is returned to verify.... So maybe keep the two defaulted shorter applications and suspend those tasks? There are no special scoring systems for this, straight points per units assigned and returned within the contest window, pps sieve tasks only.... 3 days starting at 0530 utc on the 19th.... Thinking since I'm only using gpu for this, making sure it has no tasks to work before it and setting the buffer to 3 days and allowing new tasks 5-10 minutes after the contest starts.... The server is going to be hit pretty hard when it starts.... Or would a zero buffer work to try to squeeze in and get tasks right at the start and then increase the buffer? Never know when Internet is gonna act up out here, it's slow enough as it is so I'd prefer to get everything all at once and only worry about getting them turned in.... Gonna be working on finding a higher stable oc than what I have been running on my 460.... Have it at 900/1800/2000 at 1v testing it out right now....

Is there somebody able to provide me with some assistance please? Nonetheless, when I've set Use CPU to Yes and Use NVIDIA GPU to No and then selected to crunch PPS Sieve, 12 works units were downloaded and started crunching non-stop with all my 12 CPU cores of the i7 990X processor. What I really wanted to do is just to crunch on my single GPU only while all the CPU cores are solely for WCG. RHMash

I'll see if I can get around to it.... Calculus 3 final this weekend.... Real quick, check your settings in the boinc manager.... No computer access right now, but thereshould be a drop down with CPU and gpu usage with always use, use based on preferences and don't use for both.... I have everything set to always use and I have no issues with my 460 and lag but I don't game on it.... If that doesn't work, the menu for setting CPU time and network activity and stuff has options to always use the gpu or use it after a set time of the computer being idle....

When I return home from work and that's 10 hours from now, I'll give it a go.

What I really wanted to do is just to crunch on my single GPU only while all the CPU cores are solely for WCG.
In my PrimeGrid configuration, I have the following set: Use CPU: Unchecked Use NVIDIA GPU: Checked Proth Prime Search (LLR): CPU/CUDA (Both are selected when the CUDA option is set) Cullen/Woodall Prime Search (Sieve): CUDA Proth Prime Search (Sieve): CUDA The Proth Prime Search is the one related to the Winter Solstice so you can select only that one if you like. You should not need to do any special setup as long you have attached to the project and the NVIDIA drivers are properly installed. When first starting BOINC, if you check the event log, it should tell you if GPUs were detected. Here is what mine says: 12/15/2011 5:34:51 PM | | NVIDIA GPU 0: GeForce GTX 580 (driver version 26658, CUDA version 3020, compute capability 2.0, 1536MB, 1741 GFLOPS peak) 12/15/2011 7:46:04 PM | PrimeGrid | Requesting new tasks for NVIDIA GPU 12/15/2011 7:46:07 PM | PrimeGrid | Scheduler request completed: got 1 new tasks A similar log entry should show up for you for the detection of your GTX 580. The last two lines relate to when BOINC requests for GPU work with PrimeGrid.

RHMash & linuxrouter, my GPU is processing all the 3 applications now ...thank$.  3 things that I've done to make it working are as follows;- 1. Tools > Computing preferences > processor usage > Use GPU while computer is in use (Tick this in BOINC Manager) 2. Activity > Use GPU always (Select this in BOINC Manager) 3. Your Account > When and how BOINC uses your computer Computing preferences > Edit preferences > Suspend GPU work while computer is in use? (Untick this in PrimeGrid site) Basically, I've combined the instructions as provided by RHMash & linuxrouter together to ensure that my GPU operates according to my intentions and I'm so happy now. Guys, both of you're such a great help and trust me, I'm not an IT newbie.

Is it possible for me to limit the GPU usage, % to let's say 80? Perhaps, there is some settings which I can tinkle with to control the GPU usage, % ...does anybody know? By the way, I've joined the team to crunch PrimeGrid projects.

The only way I can think of would be to use TThrottle as a work-around. It would take some playing around with some but I doubt it would allow you to crunch at a constant 80%....
There might be something for the config.xml file to control gpu usage, but I don't know it.... linuxrouter maybe?

I added links to the individual and team rankings for this challenge to the first post. http://www.primegrid.com/forum_thread.php?id=3812 They increased the size of the units, I haven't completely read through everything, but it seems to be about an extra 5 minutes for every 10 minutes of work, so my 20 min gpu units take me about 30 min now... No big deal in the end, they increased the value of the units and the time increase seems to be fairly constant....

Out of the 4 wu(s) that have been completed, the timings are from 14min 3sec (fastest) to 14min 7sec (slowest) and each is being awarded with a fixed credit of 3371.

For my 8800 it's around 1 hr 34 minutes each. I have completed and returned 7 according to the manager but none of them show up as completed on primegrid.com nor do I have any points.

I finally see the points after I forced an update from the manager. Strange that nothing on the site changes without a manually forced update - unless the timing happened to make it look that way - but it was almost 10 hours after the first one was submitted and it still said "in progress" on the website.

For your info., I'm using BOINC Manager v6.12.34 (x64) and from its main menu under Activity, "Network activity always available" is checked. Probably, that explained all those completed wu(s) are sent automatically within 15 sec.

I have the same settings, and you can see from this log section that the result was uploaded immediately after completion. However, it wasn't until a manual update, 12 hours after the upload, that the web site changed. We'll have to see if it starts updating on its own now, or if the site only updates at 9AM CST daily.
