Linux CUDA Support

Hi,

I'm not sure if this is the right forum, but has there any indication if/when CUDA support for Linux will be released for SETI@home?

Thanks,

We've had CUDA for a while. At least if you have a 64bit Linux system.

You'll need to install the cuda app yourself into your projects/seti folder and use an appropriate app_info.xml file.

Here's the app you need. Others can help guide you with the appinfo.xml if the readme with the app is not enough.

Good luck. :-)



Now if you are asking when there will be stock Linux CUDA support, someone else will have to answer that.

Ok, thanks.

Does anyone know anything about stock Linux CUDA support?

Yea I'd use the repository verison of the NVIDIA driver, not the newer ones as man they will give you problems. I think I'm at 295-ish which is Ubuntu/Mint's "nvidia-current".
I have no issues with that driver and the app I linked to earlier with kernel 3.2.0

Now if we can get a Linux developer who can build Jason's CUDA app, it can be brought in as a stock app when SETI updates to v7.

If Terror-A speaks to me really nicely, I might do some of his assumed DIY in the FLOSS way such that everyone thereafter can have their own single click custom CUDA install for s@h for Boinc.

(You never know, I might even get round to that before Berkeley ramp up for the extra number crunching onslaught. Wait a moment... Is that why they haven't automated that bit? ;-) )


The rest of various Linux systems work very nicely with or without the DIY :-p

In my experience there is always a bit of DIY involved with Linux. Take SAH CUDA for example, it's all 3rd party (without Crunch3r's and Aaron's efforts there wouldn't even be an app), and then after you install it you have to tweak "Niceness" etc. to make it crunch as effectively as "the other OS". :P

Not knocking Linux, just stating a fact.

I eagerly await the outcome of your FLOSSing

Milkyway, Einstein, Poem, WCG... All of them have stock Linux GPU apps, why is so difficult to have one here? x41g is running fine, why not make it a stock app for v6 and v7?

This is a feature that I'm very interested in. Is there any way I could help?

Quite possibly, if you're familiar with building applications under Linux ;). Check out & take a look at the sources [ https://setisvn.ssl.berkeley.edu/svn/branches/sah_v7_opt/Xbranch ], which will be right-ish for Pre-V7 builds, and require some modification for update to V7.

I've already been given some patches to apply for the Mac build, which will probably cover at least some of what's needed. Just finding time for that as I can, while the Mac build is in alpha testing an Crunchers Anonymous.

As a matter of fact, I am good at Linux development. :) I'll see what I can do with the sources. I presume that CUDA support is in the main branch?

However, my Linux machine only has an Intel GPU (Ivy Bridge). I've found an old GeForce 7300GS with 256MB of RAM. Will this work with BOINC and SETI@home?

Also, where could I find the Mac patches?

While the code cutters are listening. :)

In my experiments with Linux I found that the current x41g linux app fell over when a large number of video cards were involved.

I built a machine using 7 GTS250 GPU's. Under Windows XP 32 bit I could quite happily feed the cards using an E7200 2 core processor (GPU crunching only). Under Windows the crunching times per unit of each card were normal for a GTS250. Processor usage was around 5% to 10% per core.

I then installed a clean build of Mageia 64 bit Linux on the same hardware. I installed BOINC with the 41g Linux app and a known good app_info.xml file and known good settings for "Niceness" and other parameters.

The system fell in a heap. Processor usage climbed to around 80% per core and crunching times for nearly tripled. I then swapped out the E7200 for a quad core CPU. This made a difference but CPU usage was still high and crunching times were still 150% to 200% above normal.

Through my investigations I came to the conclusion that the problem was due to congestion on the PCIE bus, but as I'm a "hardware man" I was unable to ascertain whether this was a problem with the app or a Linux problem.

As many of the top crunchers are now running 8 GPU's in the one machine, if the Linux app is to be competitive this is something that will need to be looked at.

Thanks to all for your efforts with the Linux app. I'm not knocking, just bringing a problem to your attention.

I'm trying to compile the Xbranch linked earlier under Linux. However, I keep getting dependency errors about BOINC C++ headers. Since I'm using Ubuntu, I have installed the boinc-dev package.

However, I've noticed that the boinc header files are included with quotes. Am I supposed to have the BOINC header files in the local tree?
