[mpich-discuss] MPICH2 APP on windows

[Addepalli, Srirangam V]

Hello All.
I  am trying to run a windows nwchem executable compile in cygwin using MPICH2 libraries on a  windows cluster.  The strange this with this executable is it runs on only the system that it has been compiler on. When I try to run the executable using the command or the interface , nwchem executable fails to find the input file.

Not Working:

C:\Program Files (x86)\MPICH2\bin>mpiexec.exe -np 8 -host  compute-3 nwchem.exe
siosi3.nw
 argument  1 = siosi3.nw
  Unable to open siosi3.nw --- appending .nw
  could not open a file in permanent directory:

Working

C:\Program Files (x86)\MPICH2\bin>mpiexec.exe -np 8 -host  compute-1  nwchem.exe
siosi3.nw
argument  1 = siosi3.nw


Running a job on compute-1 works fine. ( I've compiled this application here).

Command on Compute-3  submits a job to compute-1 works.
Command on Compute-3 submits a job to run on Compute-3 does not work  (not able to read input file)

Command on  Compute-1 to Compute-1 works.
Command on  Compute-1 to Compute-3  Does not work (not able to read input file)
I think this has to do with my setup. Where should I be looking for to debug this strange issue.
