Cluster two computers for Intel MPI

Hi there, 

I have two identical computers. Each with 4-dual cores and Intel Parallel Studio Cluster edition installed. I have a Fortran code, which on a single machine takes 9 hours to run if not parallelized and 1.37 hours to run once parallelized (OpenMP). I would like to connect the two computers and take advantage of both machines at the same time. Adding the MPI layer to the code should be straightforward, my problem is much more basic. 

How can I connect the two computers? They are on the same LAN network and I can easily remote login from one into other and vice-versa, but how to I pool the two computers for MPI computation?

Thanks,

Hi Peter,

    It sounds like you want to build DYI HPC clusters. There are many sources on the Web about the subject. Are you talking about Linux or Windows based compute nodes? If you talk about Windows, here is one reference:

On Linux, it is easer, e.g., you can read this article for starters:

Hi Mark,
Thank you very much for your answer. I am using windows, so I guess the best thing would be to try to setup a HPC cluster as you suggested on the first link, and see if I run into any issues.
