CUDA and POSIX threads CUDA and POSIX threads problem

Accelerated Computing CUDA CUDA Programming and Performance

I am having some problems when using a POSIX threads program and CUDA at the same time.

I am obeying the one thread per context rule.

Are there any known problems with interactions between my (creation of) POSIX threads and cudaMalloc/general CUDA usage (i see in the crash dumps i get that libcuda.so.1 is on top of libpthread)

Sorry to be vague but i cannot track this puppy down…

Thanks

Phil.

Hi Phil -

I had a problem with MPI (MVAPICH2) and CUDA because MPI was overriding the pthreads malloc. My guess is that CUDA relies on default behavior.
