Hi Matt,
I have attached the page which explains what to modify to use PETSc with
the K computer.
Thanks

Hi,
I'm modifying my 3d fortran code from MPI along 1 direction (z) to MPI
along 2 directions (y,z)
Previously I was using MatSetValues with global indices. However, now I'm
using DM and global indices is much more difficult.
I come across MatSetValuesStencil or MatSetValuesLocal.
So what's
it to work.

Hi Timothee,
Thanks for the help. So for boundary pts I will just leave blank for non
existent locations?
Also, can I use PETSc multigrid to solve this problem? This is a poisson eqn.

Hi,
I'm also looking at the fortran version of ex22. I have some questions:
1. M,N,P are global dimension in each direction of the array. I'm abit
confused. Do you mean the no. of grid pts at the coarse level? Hence, if my
problem has 27x27 grid pts, do I use M=N=9 with 3 multigrid levels or
and is usually detrimental to solver performance.?
But you mention abt latency, so shouldn't minimizing the number of neighbor
processes reduce latency and improve performance?

For e.g., for 2 processors, to 2 55x70 grids, or 2 110x35 grids.

If this is a MPI problem, then you can just ignore it. I'll check it in
some MPI forum.
