Since the library is based on the published MPI 1.1 standard, there
should be minimal portability issues provided you're using a conforming
As a quick check, I just tried it on our Sun-Fire cluster with Sun's
HPC MPI and it worked okay. Just had to setup
setenv MPICXX /opt/SUNWhpc/bin/mpCC
setenv MPIRUN /opt/SUNWhpc/bin/mprun
setenv MPIBUILD "<include>/opt/SUNWhpc/include <define>_MPIPP_H"
The define is to skip inclusion of the MPI C++ headers.
Thanks for the library Doug. I like the looks of your all_reduce, it
looks very similar to what we did.
