[mpich-discuss] MPICH2 APP on windows

[Jayesh Krishna]

Hi,
 You can try to manually map the network share (using the same
username/password that you used/registered for the MPI job) from machine
compute-3 and see if you can access the files.
 
Regards,
Jayesh

Hi,

Thank you. It worked to a extent as in when I run the command with the
suggestions I am able to get past read input file stage.

 

NOT Working:

 

C:\Program Files (x86)\MPICH2\bin>mpiexec.exe -np 8 -host compute-3 -map
H:\\JAN

US\D H:\BIN\nwchem.exe H:\BIN\siosi3.nw

 argument  1 = H:\BIN\siosi3.nw

  could not open a file in permanent directory:               H:/BIN/

  could not open a file in scratch directory:             H:/BIN/

  Both permanent and scratch directory not accessible

 

Working:

C:\Program Files (x86)\MPICH2\bin>mpiexec.exe -np 8 -host compute-1  -map
H:\\JAN

US\D H:\BIN\nwchem.exe H:\BIN\siosi3.nw

 argument  1 = H:\BIN\siosi3.nw

 

I think I have some permissions messed up. Suggestions ?

 

Rangam

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.
