[mpich-discuss] About using g95 to compile MPICH2 problem

Tue Oct 9 13:54:50 CDT 2012

Dear MPICH2 users,
  Thanks.
  I asked other program users, he suggested me to try to use mpich2-1.2.1p1
version.

  I used WindosXP, Cygwin and g95 to install MPICH2-1.2.1p1 on my personal
computer (Intel Core2 Quad Q8200).
  Now, I can use mpirun to run my cases by set n=1.
  But, I have some doubts about "n" .

  In my research, I need to couple another models.
  So, I need to use the least two processors.

  I use mpirun -n 2 to run my case, and get some error messages
  rank 1 in job 2 980622-05_3343 caused collective abort of all ranks
  exit status of rank 1: killed by signal 9
  rank 0 in job 2 980622-05_3343 caused collective abort of all ranks
  exit status of rank 0: return code 0

  But, I could run cpi using more than 2

  Can anyone give me some advices?

Best regards,
Chi-Che Hsieh
