[petsc-dev] Using cuBlas as the vendor blas for PETSc

I was wondering if anyone had ever tried using cuBlas as a substitute for
something like MKL with PETSc.  I've been wondering if it would give better
performance than MKL for my direct solves with cholmod even though the block
sizes are small for cholmod i.e. 32x32 is the default I believe.  If so, were
there any tricky aspects to using cuBlas in this way?

Thanks,

Dave
