Ok, I thought I posted this before, but I guess I forgot. My GeForce GT430 gets computation errors on a fresh install. I don't know if all the cards are like this, but I have to keep a CPU core available for the GPU to crunch. So on this Athlon x2 I'm crunching one CPU unit and one GPU unit.

I CPU core per task is required for Nvidia cards. With ATI cards you can split the CPU cores (run 2 tasks or more per CPU core depending on your hardware) and run multiple tasks.

A little more research shows that the HD 6670 and HD 7750 are both better performers. The 7750 seems to be top end from what I can see. Any other options for a GPU that doesn't require an external power connection?

The 7750 is the best that doesn't require an additional 6 pin PCI-E connector. You can buy 4 pin molex (the ones that power HDDs) to 6 pin PCI-E adapters for a few bucks and run higher capacity cards if that is a choice for you. Most of the newer cards come with the adapters. Just check before you buy.

The Goober posted : I just repaired one desktop and will be putting another into service soon. The one I just fixed is an HP with PCI-e x16 slot, but no 12 volt rail for graphics. So it got me to thinking, "What is the best GPU you can get that doesn't require a 12 volt rail?"

I found a thread on Tom's Hardware, but it's 2 years old. So I'm not sure if there is anything newer out that would trump what they listed. But here it is.

»www.tomshardware.com/forum/28715···al-power

I checked out their reccomendations and the best card that can still be easily found seems to be the Radeon HD 5670. I'm wondering what other options are available without upgrading the PS.

1: Set the project to "No new task"
2: Quit BOINC
3: Edit app_info.xml
4: Set avg_ncpus = .75
5: Set max_ncpus = .75
6: count = .12
7: Save
8: Run BOINC

Once you run out if task, rename app_info.xml to app_info.old

Since you only want to crunch on GPU, make sure your Device Profile is set accordingly. »secure.worldcommunitygrid.org/ms···vices.do

Upgrade your BOINC to version 7.0.42
Run BOINC
Check if you have GPU Task
If you have, create projects\www.worldcommunitygrid.org\app_config.xml

app_config.xml (Contents):

Just an FYI. If you want to run an app_config file that allows you to run multiple GPU tasks at the same time you'll have to upgrade your version of boinc to 7.0.42. It will not work with any version lower than that. It's very simple to set up if you'd like to try it and I can give you easy to follow instructions. All I need to know is your OS, type of video card and size of PSU.

I'm running Win 7 x64 Enterprise with two 7970Ghz editions and a 1200 watt PSU.

This is my current config using BOINC 7.0.28 and it seems to be working with 6 GPU tasks per card. I did this because I have a 3930K so there is one task per CPU thread. I only want to crunch on the video cards.

Please let me know what I should change.

DadeMurphy posted : glennaxl got it right, the config I'm using gives me 5 per card for 10 total.

I'm going to try out running 2 gpu tasks on my card and 5 cpu tasks on my workstation (The system with the gtx580). This will leave one core unloaded on my workstation and should give me a very good balance of WUs processed/system responsiveness (this is my main work rig and I don't want it to bog down on me).

Probably a good call on the 580. Maybe a 50/50 split on the CPU cores for starters and then some trial and error to find the best mix.
EDIT: Glenn knows about Nvidia. Follow his lead on the tasks for that card. You can add code to his proposed app_config file to split up your remaining CPU cores on other tasks any way you'd like.

Since I had a power outage today I decided to change over from an app_info setup to an app_config setup. I used the configuration below, let me know what you think.

hcc110.2.8

System hardware

Intel Core i7 2600K
2 x ATI Radeon HD7950
16GB RAM

Also tomorrow I'm going to be installing a GTX 580 into my workstation, it's a dual Xeon E5440 box with 12GB of RAM. I'm thinking since the Nvidia line is so much weaker in the compute space that this box will likely run a mix of gpu and cpu tasks. What are your thoughts?

Your app_config looks good as a starting point. Increase as needed. You will probably end up running 7 instances for each gpu.

For your workstation, you can use this:
hcc12.501

In my experience with 580, 2 was the max.

You should stop using app_info but instead use app_config.

app_config.xml (example if you have 7970 & 8 core CPU):
hcc110.10.8

Nanoprobe and I, have been running 10 instances on our 7970 with 8 core cpu.

To answer your question, avg_ncpus and max_ncpus, they are used for allocating CPU %. So to run 10 instance on an 8 core cpu, your ave and max would be .80

JoelC707 posted : Well, that would explain why I only have 19 pending GPU tasks on this computer. Honestly I expected this would happen. At the rate we are churning through them (and I mean all of us on WCG as a whole), it's no wonder they are running low. This isn't like CPU crunching where you have an hour or several turnaround time per WU and can keep a steady stream flowing in both directions. I'll bet all the uploading and downloading of the WUs in such short order is wreaking havoc on their bandwidth and storage system.

They even mentioned 100 days of WUs is 5TB on their servers. I'm sure they have plenty of space to process all the completed WUs on their back-end systems, but they probably didn't plan for that much space being needed on front-end systems. I certainly wouldn't have expected that much but I'm also not working on the project either :p

JoelC707 posted : It was a fairly recent change so depending on how quickly you go through your cached WUs, it could take a few days to see the new ones. I haven't calculated mine against the new ones yet but with the old WUs, I calculated that if I shut off getting new tasks it would be out of GPU WUs in about 8 hours with a "full" task log (well, full as in what was shown in the task list).

In case you're wondering why I calculated that, I wanted to run out the saved WUs so I could reformat a computer and didn't want to just abort the tasks. I wanted to see how long I would have to wait before I could proceed. So I simply decided to do it the next day, set it to not get tasks before I went to bed and by morning it was sitting idle.

JoelC707 posted : Ahhh OK so it's not that it's running two tasks concurrently, but it's running double the amount of work. To be honest, I haven't looked at my cache settings in BOINC. I have noticed over the last while that when I look through the logs it tries to fetch work and gets told "no new tasks for project" and "this computer has reached the limit of in-progress tasks". Admittedly, this could have been fixed with this update as I rebooted from a power outage the other day and don't see any such messages in the logs now.

So this means people with modified app_info files to run 2 tasks at a time are now running 4 tasks at a time? If so, should they re-examine their GPU load and such to make sure they aren't overloading them? Either way I can see this being a better choice as I was frequently at the task limit per computer and it was constantly transferring data back and forth with how quickly it was churning through them.

All this change means is each WU contains twice the amount of work. It will not change the app_info settings. The task limit per GPU is now 4500 per day. Are you sure that's the problem? Try increasing your cache settings.
