[petsc-dev] development version for MATAIJMKL type mat

[Bakytzhan Kallemov]

Hi,

My name is Baky Kallemov.

Currently, I am working on improving a scalibility of  the Chombo-Petsc 
interface on cori machine at nersc system.

I successfully build the libs from master branch with --with-openmp and 
hypre.

However, I have not noticed any difference running my test problem on 
single node KNL node using new MATAIJMKL

type for different hybrid mpi+openmp runs  compared to regular released 
version.

It seems that it made no difference, so perhaps I am doing something 
wrong or my build is not configured right.

Do you have any example that makes use of threads when running hybrid 
and show an advantage?

I'd like to test it and make sure that my libs are configured correctly, 
before start to investigate it further.


Thanks,

Baky
