Are there any "hard coded" limits in the size of a Open MPI pool? How about the maximum amount of nodes running a single job? Which factors should be taken in to consideration when building large clusters? For an example what kind of limits does the OS set, etc.
Most commercial parallel computing environments seem to have a restriction of 100-256 nodes. Our project requires more. Any solutions? It's not always possible to "split" the data into x starting points and use a batch system to launch x jobs on several independent pools and then wait for the results and combine them. Help would be appreciated. Thank you! Sebastian Forsman
