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

[tetsuro_kikuchi at jesc.or.jp]

Hello. I'm a new MPICH2 user.

I would like to run a program on my Linux workstation using MPICH2 (version
2-1.4). The processors, Linux OS and compiler that my machine uses are as
follows:

Processors: Intel(R) Xeon(R) E5507 processor (2.26 Hz, 4 core) × 2
Linux OS: Ubuntu 11.04 (natty)
Compiler: Intel(R) Fortran Composer XE 2011 for Linux (Update 4)

When I execute the run script of the program, it failed with the following
error message:

[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

Could anyone teach me what is wrong and how to solve this problem? I attach
below the run script of the program ("run.cctm_script.txt") and its whole
error log generated this time ("run.cctm_errorlog110620.txt"). In addition,
the machinefile as which mpiexec use in this program ("machines8.txt") is
also attached. (Please refer to the bottom part of the attached run
script.)

The hostname of my machine is "jesc-HP-Z800-Workstation". The file "hosts"
located in /etc directory is also attached below.

Kind regards,

Tetsuro
