Hi

It's the first time I try to run the GPU app, and I had my two first tasks fail with exit status 127. Both were the "Binary Radio Pulsar Search (Arecibo) v1.00 (BRP3cuda32nv270)" app.

Stderr output

6.12.34

process exited with code 127 (0x7f, -129)

]]>

The GPU is recognized by BOINC as

Tue 01 Nov 2011 08:21:17 PM CET |  | NVIDIA GPU 0: GeForce GT 420M (driver version unknown, CUDA version 4000, compute capability 2.1, 1024MB, 128 GFLOPS peak)

I have a GPU task running at the moment for GPUgrid, it seems to be running fine.

I'm on Ubuntu 11.10, and running ironhide to enable the Nvidia card. (Nvidia Optimus configuration)

A bit of googling makes me think the exit status 127 points to a library problem, but I get no indication as to which.

Any ideas?

GPU app fails with exit status 127

Got the GPU app running now. Turned out my libcuda could not be found.
Running
ldconfig /usr/lib32/nvidia-current
fixed the issue.

today i updated my ubuntu

today i updated my ubuntu 11.4 computer to 11.10 (oneiric ocelot)
and original boinc client stopped functioning, since there was no more
some libraries needed by system.

i downloaded boinc files from oneiric distribution and faced same problem
as knorr did, cuda works terminate with computational error.

this hint to make ldconfig with current nvidia files fixed my problem

thank you for valuable hint.
