[mpich-discuss] MPICH2 APP on windows

[Jayesh Krishna]

Hi,
 If you are sharing your input file across different machines using a
network share you must use the "-map" option of mpiexec to map the network
share for your job (Please refer the window's developer's guide for more
details on the mpiexec options - available at
http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=
docs).
 Also try specifying the complete path for the input file (eg:
c:\testpgm\siosi3.nw).
 Let us know the results.
 
Regards,
Jayesh

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.
