Dear List,
I would like to gather the data from several processes.
Instead of the comonly used stride, I want to interleave
the data:
Rank 0: AAAAA -> ABCDABCDABCDABCDABCD
Rank 1: BBBBB ----^---^---^---^---^
Rank 2: CCCCC -----^---^---^---^---^
Rank 3: DDDDD ------^---^---^---^---^
Since the stride of the receive type is indicated
in multpiles of its mpi_type, no interleaving is
possible (the smallest striping factor leads to
AAAAABBBBBBCCCCCDDDDD).
Is there a way to achieve this behaviour in an
elegant way, as MPI_Gather promises it? Or do
I need to do Send/Recv with self-aligned offsets?
Thank you for your help!
Michael
