If you are running on a Windows 7 workstation and would like to use Microsoft MPI (MS-MPI) for your CAE solver code like RADIOSS, LS-DYNA etc. you can download it for free from here. Just double click install the MS-MPI executable, and then you can run standalone on your workstation.
For example, to create a simple double click batch script to run your MS-MPI LS-DYNA MPP job from any directory, copy and paste the below into “run.bat” in the same directory as your key file my.k
mpiexec -np 12 c:\soft\lsdyna\mpp971_d_R5.1.1_winx64_msmpi.exe i=my.k
For big jobs you would want to run on your Linux or Windows cluster, a nice interface for LS-DYNA submission is the TotalCAE portal which also does license aware job submission for the LSTC floating license server.
