Hi Håkon,

I just read

I am lacking applications using MPI_Alltoall and MPI_Alltoallv - these
are important dimensions to evaluate. Anyone who knows about any
suitable benchmark candidates?
Thanks, Håkon

Thanks for the publicity on the forthcoming cluster-relevant
benchmark-suite from SPEC. It is due to be launched at ISC'07 in
Dresden in late June. I am on the SPEC HPG committee that is developing
the SPEC MPI2007 benchmark suite, and we would welcome more members to
participate in developing these benchmarks, including Scali :)
Are you lacking "applications using MPI_Alltoall and MPI_Alltoallv" or
are you pointing out their lack in MPI2007?
Thanks for pointing this out to us. I did some searching and a
molecular dynamics code named CPMD and a weather code named Hirvda (an
"operational weatherforcast used by several weather centers in Europe")
both use MPI_Alltoall extensively.
I hope these applications will suit your needs. If others on the list
can suggest more of these types of applications, that would be great.
It is too late for adding candidate codes for the initial release of
MPI2007 which ships with what is called "medium" datasets. There are
plans for more scalable versions of the suite in the future with at
least Large and perhaps XL datasets. With those releases there is the
possibility to add more codes, and we will seriously consider codes that
use MPI_Alltoall*.
Thanks,
