[mpich-discuss] Error 123

[Phelan Jr., Frederick R. Dr.]

I ran this with the WMPIEXEC program and the -verbose option. The lammps program never executes. Is the output file in anyway meaningful as to why?

Fred

Fred,

I use a program that takes command line arguments. For example a typical call would be: 

mpiexec -n 12 -f nodefile mcnp5.mpi -i input -o output wwinp=wwfile 

I have never run into the problems you have describe.

There is now question that what is happening here is related the seeming inability of the mpiexec to run a program that requires command line arguments, which in some cases involves use of the < symbol. However, -i can also be used in place of < ... the results is the same.

At this point I have tried every conceivable variation:

a) C:\LAMMPS\example\micelle>"C:\Program Files\MPICH2\bin\mpiexec" -n 2 -dir c:\lammps\example\micelle\ c:\bin\lmp_win_mpi.exe < c:\lammps\example\micelle\in.micelle
Result: Does not recognize data redirection and lammps exits

b) C:\LAMMPS\example\micelle>"C:\Program Files\MPICH2\bin\mpiexec" -n 2 -dir c:\lammps\example\micelle\ "c:\bin\lmp_win_mpi.exe < c:\lammps\example\micelle\in.micelle"
Result: Error 123

c) C:\LAMMPS\example\micelle>"C:\Program Files\MPICH2\bin\mpiexec" -n 2 -dir c:\lammps\example\micelle\ c:\bin\lmp_win_mpi.exe -i c:\lammps\example\micelle\in.micelle
Result: Does not recognize command line arguments and lammps exits

d) C:\LAMMPS\example\micelle>"C:\Program Files\MPICH2\bin\mpiexec" -n 2 -dir c:\lammps\example\micelle\ "c:\bin\lmp_win_mpi.exe -i c:\lammps\example\micelle\in.micelle"
Result: Error 123

Does anyone have a working example of running using mpich that runs a program that makes use of command line arguments?

Thanks,
Fred

This part of your command line looks problematic:

> ... "c:\bin\lmp_win_mpi.exe < c:\lammps\example\micelle\in.micelle"

I'm neither a Windows nor a LAMMPS user, but at least on most Linux/Unix shells, quoting a redirection symbol prevents the shell from interpreting it as such, e.g.

  "program name" "foo bar" < "input file"

looks quite reasonable, while

  "program name" "foo bar < input file"

seems odd, since that would pass the whole 2nd string (incl. `<') as an argument to the program.

Hope this helps,
Nicolás
