Most of you will not remember this, but one of the DARPA projects that I worked on a decade ago (besides MPIRT) was the Data Reorganization
It was a specific set of collective operations to replace "MPI_Alltoall*" with more scalable and
It has been implemented with non-MPI-specific APIs for DOD-based parallel computers, and it has been reused in part
by people doing VSIPL++.
There is a lot of interesting information here on specific high performance collective operations related to data motion,
and I want everyone doing MPI-3 to know about it. If there is interest, we could develop proposals on bringing in
some of these capabilities into extended collective operations for MPI-3.
