Hello,
I wrote an f90 mpi code to solve a 3D problem. The topology is
obtained using mpi_cart_creat. At the end of the calculations I wish
to get the results gathered from all processors into one big 3
dimensional array that can be directly visualized without going
through post-processing. The problem is that mpi_gather doesn't
gather the results from the different proccessors as blocks.
for example, in 2D, if proc. 1 has the following
1 1 1
1 1 1
1 1 1
and proc. 2
2 2 2
2 2 2
2 2 2
then mpi_gather results in the following
1 1 1 1 1 1
1 1 1 2 2 2
2 2 2 2 2 2
the results that I'm after would be
1 1 1 2 2 2
1 1 1 2 2 2
1 1 1 2 2 2
is there an easy way to do this?
