Yes. I haven't tested my code on MPICH. Because MPICH don't support infiniband in the supercomputer. But I have tested code on mvapich. It also has bugs, when the finite mesh is larger than 50M.
Now, I just want to know if you will change to use point-point. If you would not, I will try to rewrite PetscSF for me.
