[MPICH] mpirun issue on Windows XP

[David Ashton]

Duane,

MPICH.nt.1.2.5 is no longer supported and users should migrate to MPICH2:
http://www.mcs.anl.gov/mpi/mpich2

MPICH.nt.1.2.5 uses a temporary file to communicate between mpirun and the
root process.  There can be sharing and naming issues with this temporary
file.  Try deleting all mpi*.tmp files on your system and then run mpirun
again.

You will get better performance and a more stable startup process if you
switch to MPICH2.

Subject: [MPICH] mpirun issue on Windows XP

Hi,

I am new to mpi and am using mpich.nt.1.2.5 on a machine running Windows
XP Service Pack 2.  The problem I am having is when I execute mpirun I
get the following error message:

./mpi/mpirun -np 2 cpi.exe
Error 32, process 0, host Vertex:
     CreateFile failed: .\mpi3D.tmp
Wait for process 0 to write port to temporary file timed out

I am running everything from a Cygwin Xterm.  Anyone have an idea as to
what might be causing this error?

Thanks,
Duane
