Dear MPICH-experts,

Recently I've downloaded the version 1.00.12 of MPICH.
Unpacking, configuration and making were O.K. And after that I've
attempted to MPI-run the test examples/basic/cpi (which is included
in the distribution). The results were strange:

Attempt No 1 - single process:

  mirror% mpirun -np 1 cpi -mpiversion
  Process 0 on mirror.ccas.ru
  MPI model implementation 1.00.12., ADI version 1.30 - transport p4
  Configured with -arch=sun4 -device=ch_p4 -nof77 -no_mpegraphics
  pi is approximately 3.1416009869231254, Error is 0.0000083333333323
  wall clock time = 0.003817

Attempt No 2 - two processes on the single computer:

  mirror% mpirun -np 2 cpi -mpiversion
  p0_711:  p4_error:  Timeout in making connection to remote process on mirror: 0
  bm_list_712: p4_error: interrupt SIGINT: 2

Hence, the test can't work in the simplest case - two processes on the single computer!!!

Output of uname -a:

  SunOS mirror 4.1.3 3 sun4m

File $MPIR_HOME/bin/machines/machines.sun4 exists and contains "mirror", repeated 5 times.

BTW, I've sent a similar complaint to mpi-bugs@mcs.anl.gov - no reply...

Thanks in advance,
