[petsc-users] Intel MKL Sparse blas

[W. Miah]

Hi Richard/Barry,

I don't have any particular need just yet, but since most HPC clusters have
Intel CPUs, I think an Intel Sparse MKL PETSc branch would bring immediate
optimisations. I do realise that it does require quite a bit of work as
Intel probably didn't design the API that well and which will require some
re-factoring. I'm CC'ing Gennady from Intel whom I spoke to about this.
Perhaps the MKL branch work can be coordinated with him.

Regards,
Wadud.
