Hi James,
I think a benchmark that tests as part of it the GFlops of the
cluster using any MPI like openmpi or mpich2
would be nice. Similar to HPL. But OSCAR primaririly is for Cluster
building. So it should work with mpich and lam and openmpi.
Intel has come up with a C++ and Fortran Compiler with Cluster OpenMp
support. GNU compilers do not have this ( with distributed memory in a
global address space
in which every byte and cpu and components of Cpu's(FPUs ALUs INT units
cache,etc),RAM are addressable including virtual memory.
As we move into multicore processors OSCAR benchmarking should support
shared memory nodes with diffrent interconnects such as GIGEthernet etc.
and shared CPU caches. So the intel compiler though not free if
accomodated with abenchmark similar to HPL but incorporates Cluster Open
Mp and distrubuted memory support would be nice.
A benchmark that supports MPI and Cluster Open Mp and gives numbers of
performance in GFlops for lin alg problems and also tests network
bandwidth would be nice!
My 50cents= 25(Quarter)* 2cents

Allan Menezes
