Configuring Your Environment

When submitting a job, mpirun will try to interpret your current directory or the
MPI_WORKDIR option as a network path, and set the job 'working directory' to the current
directory, or MPI_WORKDIR if provided. It will construct the stdout and stderr filenames from
the root name of the rank, and append the jobid and taskid to the filenames, with the
extensions .out and .err respectively.
The following is an example of submitting a job via the automatic submittal:
C:\Documents and Settings\smith>"%MPI_ROOT%\bin\mpirun.exe" -ccp -np 6
\\share\directory\smith\HelloWorld.exe
mpirun: Submitting job to scheduler and exiting
Submitting job to ccp scheduler on this node
mpirun: Drive is not a network mapped - using local drive.
mpirun: HPMPI Job 1116 submitted to cluster mpiccp1
This will schedule and run 6 ranks of HelloWorld.exe. Standard output and standard error
are placed in the current directory, 'HelloWorld-1116.1.out' and 'HelloWorld-1116.1.err'
respectively.
The following example changes the directory to a share drive, and uses the current directory
as the work directory for the submitted job:
C:\Documents and Settings\smith>s:
S:\>cd smith
S:\smith>"%MPI_ROOT%\bin\mpirun.exe" -ccp -np 6
-hostlist mpiccp1,mpiccp2 HelloWorld.exe
mpirun: Submitting job to scheduler and exiting
Submitting job to ccp scheduler on this node
mpirun: HPMPI Job 1117 submitted to cluster mpiccp1
Here the 'S:' drive is interpreted as the mapped network drive. The rank HelloWorld.exe is
located in the current directory, and the stdout and stderr files are placed in the current
working directory.
