7 Local info (compile, link and run)

Currently, we have two multi-host systems. One is a 4-host system (g6host0 through g6host3) and the other is a 2-host system (g6host6 and g6host7). The machines g6host4 and g6host5 exist, but without GRAPE-6 boards yet.

7.1 Compile and Link

To compile and link MPI programs, use mpixx (f77, cc, CC) with an enviromental variable

     setenv MPIROOT /opt/mpich/mpich-p4/mpich-1.2.1

This MPICH is based on GCC version egcs-2.91.66.

7.2 Run

To run a 4-host program, use mpirun -np 4 on g6host0 (when it's ready...).

To run a 2-host program, use mpirun -np 2 on g6host6.
