Jonas,
In case I misunderstood your question and you want to print
v_glob on P0: 9x2
0 9
1 10
2 11
3 12
4 13
5 14
6 15
7 16
8 17
then you have to fix the print invocation
// note: print an additional column to show the displacement error we get:
if (!rank) print("v_glob", rank, n, m,
Jonas,
Assuming v_glob is what you expect, you will need to
`MPI_Type_create_resized_type()` the received type so the block received
from process 1 will be placed at the right position (v_glob[3][1] => upper
bound = ((4*3+1) * sizeof(int))
Cheers,
Gilles

Dear OpenMPI community,
Here's a little puzzle for the Christmas holidays (although I would
really appreciate a quick solution!).
I'm stuck with the following relatively basic problem: given a local
nloc x m matrix X_p in column-major ordering on each MPI process p,
perform a single
