I’m trying to use nvblas as a drop in replacement for BLAS in things like R or numpy. I installed the CUDA 6 RC on Ubuntu 13.10 fine and normal CUDA applications run without issue. When I try and run something that calls BLAS though I get the following error:
csevers@titan1:~$ LD_PRELOAD=/usr/local/cuda-6.0/lib64/libnvblas.so R
[NVBLAS] Cannot open default config file ‘nvblas.conf’
Segmentation fault (core dumped)
The command is from this presentation by the way:
The CPU blas install I have is OpenBLAS built from source. That works fine.
Any ideas? I would really love to get this working.
