Hi,
with all the argument about performance of so called Swiss
Army Knife (SAK) MPIs I have uploaded four runs of the HPCC
benchmark to the HPCC benchmark web site to show the performance
of a single cluster with a single SAK MPI running with four different
Interconnects, GigaBit Ethernet (tcp), SCI, Myrinet and InfiniBand.
The results can be found at :
http://icl.cs.utk.edu/hpcc/
Look for the Dell PowerEdge 2650 cluster with 32 CPUs.
The results show that it is possible to have a SAK MPI that
show acceptable performance for a multiple of interconnects.
The SAK MPIs are of great value for the application
vendors as they are free from the extra work involved with
a new MPI implementation for every interconnect.
In addition an application can be moved without changes
from one cluster with one interconnect to another cluster
with yet another interconnect.
