Re: HCC GPU app close to going live IT HAS LAUNCHED

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

I'm out of tasks on 4 of 6. On to something else for now.

I keep a 3 day cache and only crunch when the PC is not in use. That gives it about 12-16 hours a day of crunching. So probably about 5 days to burn through my WUs.

Hopefully they'll get things going again by then.

Latest update from the techs at WCG on the WU shortage.

quote:
Great news everyone. We are in the process of downloading new work from the researchers. Instead of sending out a trickle as they arrive because everyone is starving for work today. We will more than likely be able to release them and set the project back to full weight tomorrow. This is barring any delays of course. We will try to keep you up to date and informed of any changes that may happen.

Thank you for your patience,

Machine is on overdrive and using 400W of power. Keeps me nice and warm during the winter. Heater uses slightly more.

It says 396W in case it's hard to read
Actually that's on an APC battery backup. Here's mine

That's actually with two i5-3450 machines (one has a 5830, the other a 6870) and three 22" LCD monitors.

I just had to change back to CPU crunching on my GPU rig, I wasn't getting any GPU WUs. Anyone else seeing the same?

All i got are re-sends and sporadic.

What PCI only GPU cards work?
Not pci express.

Everything I have looked up so far is on the bad list.

PCI is a shared bus system and not nearly fast enough. If there were a usable GPU on a PCI bus I don't think it would work that well which is likely why you haven't found one yet. That said, you might be able to find an AGP version. IIRC there were some AMD 5000 series made with an AGP interface.

What does the avg_ncpus and max_ncpus command do in the app_info.xml files?

I run GPU crunching only and not sure if they are needed. I cant seem to wrap my head around what they do.

You should stop using app_info but instead use app_config.

app_config.xml (example if you have 7970 & 8 core CPU):
<app_config>
<app>
<name>hcc1</name>
<max_concurrent>10</max_concurrent>
<gpu_versions>
<gpu_usage>.10</gpu_usage>
<cpu_usage>.8</cpu_usage>
</gpu_versions>
</app>
</app_config>
 

Nanoprobe See Profile 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

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.

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.

<app_config>
<app>
<name>hcc1</name>
<max_concurrent>10</max_concurrent>
<gpu_versions>
<gpu_usage>.2</gpu_usage>
<cpu_usage>.8</cpu_usage>
</gpu_versions>
</app>
</app_config>
 

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:
<app_config>
<app>
<name>hcc1</name>
<max_concurrent>2</max_concurrent>
<gpu_versions>
<gpu_usage>.50</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_versions>
</app>
</app_config>
 

In my experience with 580, 2 was the max.

Does that app-config give you 5 or 10 tasks on each card?

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.

Its should be 5 per card.

On my dual 7970, I have this app_config which runs 9 per card:
<app_config>
<app>
<name>hcc1</name>
<max_concurrent>18</max_concurrent>
<gpu_versions>
<gpu_usage>.11</gpu_usage>
<cpu_usage>.66</cpu_usage>
</gpu_versions>
</app>
</app_config>

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).
