Question How to get Boinc 6.4.5 to use CUDA

I've installed the Boinc 6.4.5 x86_64 using F10 update package from Fedora repo.
The client runs fine using the CPUs, but doesn't fing the nVidia display processors.

I've installed nVidia drivers using Fusion repo packages for F10 ( currently 180.25 )
nVidia display settings seems happy and correctly reports driver 180.25 in place as well as 9600 GSO graphics card and LCD monitor.

My objective is to get Boinc using the CUDA capabilities of my GeForce 9600 GSO graphics card and see some of the performance benefits advertised.
Although Boinc client is running it will only use the CPU to do work. I have not been able to discover any flags or configuration settings to help Boinc find CUDA library files.

I'm stuck at the limits of my knowledge. Any help would be appreciated. ( including a more appropriate forum if required)

The following are the startup messages from Boinc. I'm assuming the fact that it can't find the library causes the inability to see the GPU coprocessor.

The same problem happens on mine Fedora 10 i386.

I tried
Code:
yum provides */libcudart
, no result was found...

Guys,

libcudart comes from the Cuda Toolkit download from the Nvidia site.

From my initial poking around, I've not found an RPM that provides this yet, but these are early days. I'm not interested in BOINC per se - more coding applications direct for CUDA, but part of our journeys appear to be in parallel.

The installation of the toolkit is pretty trivial and simply involves running the script and editing your PATH and ld.so.conf.

I'm certainly running Cuda code on Fedora 11 x86_64 at the moment, but it is only by downloading and installing the drivers from Nvidia - not by using any of the RPMs that are available.

Hope this helps

Cheers

Duncan

I had cuda running with the direct from nvidia drivers. 185something and the boinc client a few months ago for a project. As I remember, the project has to support cuda, not just you. Installing the nvidia drivers for linux AFAIK provides you with all the cuda drivers. It's not like Windows where there is the vid drivers and then cuda binaries as well.

You can run CUDA apps with the rpmfusion nvidia driver also

Hi, does someone know whether the 256M on board graphic memory is one of the minimum requirements for CUDA ? I have a GeForce 8400M G with only 128M on board graphic memory but I could allocate up to 512M memory from system main memory.

It depends ... "Many CUDA programs require at least 256 MB of memory attached to the GPU."
