[petsc-dev] Goto BLAS

[Dave Nystrom]

I was wondering if anyone has experimented with using Goto BLAS with Petsc
for algorithms that make heavy use of blas and if there is any idea how it
compares to Intel MKL.

I'm finding that using Intel MKL with umfpack is speeding up my sparse direct
solves by about 2x.  I'm just using default parameters with umfpack and have
not yet tried to tune any of the various configurable parameters.

Thanks,

Dave
