[mpich-discuss] MPI scatter algorithms for BlueGene/P

[Khalid Hasanov]

Hello,

First of all, I am not sure if this group is the right place for this
question. If not I apologize for asking unrelated question.

I read two papers about optimizing MPI collective communications on BG/L
and BG/P.
(Optimization of MPI Collective Communication on BlueGene/L Systems
and MPI Collective Communications on The Blue Gene/P Supercomputer:
Algorithms and Optimizations respectively). However, these two papers do
not mention anything about MPI scatter and gather operations, I wonder if
these two collective operations have been optimized for BlueGene or they
use exactly the same algorithms from MPICH. Any reference appreciated.


Best regards,
Khalid
