Hi everyone, I am having trouble developing a complicated parallelization algorithm with MPI and I'm hoping for some tips (I am using OpenMPI 1.10.2). I posted the latest problem I ran into on Stack Overflow and got a response from someone saying they don't think it is possible to do the spawn allocation that I want.
You have all been very helpful in the past, so I am hoping to get your opinions. Briefly, I am trying to oversubscribe cores to run spawned processes while the main program's processes sit and wait in a barrier. Because the syntax highlighting is better, it might be easiest to look at my post on Stack Overflow than me trying to paste it in an email. Please see this link: http://stackoverflow.com/questions/38087327/mpi-spawn-not-enough-slots-available-all-which-nodes-are-allocated-for-this-j Thanks for your help, Jason
