[mpich-discuss] Problem in running a program with MPICH2

[tetsuro_kikuchi at jesc.or.jp]

Thank you for your quick reply, Rajeev.

When I run cpi using the same machine file used by my application, it
returned error messages as follows:

$ mpiexec -f $M3HOME/scripts/cctm/machines8 -n 8 ./cpi
[mpiexec at jesc-HP-Z800-Workstation] HYDU_sock_is_local
(./utils/sock/sock.c:536): unable to get host address for rain4 (1)
[mpiexec at jesc-HP-Z800-Workstation] main (./ui/mpich/mpiexec.c:356): unable
to check if rain4 is local

Try running it across machines using the same machines file used by your
application.
