Tips and tricks - FAQ


Are there any DAPL* implementations available for Microsoft* Windows*?
Yes. Find Windows OpenFabrics* (WinOF*) at OpenFabrics* Alliance website http://www.openfabrics.org/downloads/WinOF/


How to run the Intel® MPI Library application located on network resource?
Use the mpiexec -gwdir or -wdir options to specify working directory for the application.

For instance: mpiexec.exe -machinefile machine_file -n 4 -wdir \\host\share_folder IMB-MPI1.exe


How to pin processes to prevent undesired process migration?
The Intel MPI Library automatically pins processes to the CPUs to prevent undesired process migration. Use the I_MPI_PIN, I_MPI_PIN_MODE and I_MPI_PIN_PROCESSOR_LIST environment variables to control process pinning.

For example: mpiexec -env I_MPI_DEVICE shm -env I_MPI_PIN enable -np 4 ./prog
