Hi all,
I'm trying to get pgenesis, a neural simulation environment, to work on BG/L. It consists of an interpreter for a csh-like scripting language and an integrator, among other things, all in the same binary.
It compiles (with some minor modifications) and runs, and the script interpreter runs fine on all nodes; however, when we try to call the integrator, it seems to hang waiting for messages from node 0. The same scripts work on Jazz.
Is there anything special about MPI node 0 on BG/L? If so, is there some documentation I can look at? In the mean time, I am trying to see if our model will run if we avoid integrating on node 0; of course, we would like to understand the problem so we have some confidence in any results we get with the workaround.
Thanks for your help!
