Just some other questions on ras functions: - we found this old thread in which you said that orte doesn't allow to spawn processes outside ras allocation (e.g. with MPI_Comm_spawn). Is it still like that? So, allocate() function is

Thank you. And, to workaround, is it possible to temporary suspend processes on a node and later resume it (requested by RM)? I saw in the code that orted can receive SIGTSTP and SIGCONT to suspend/resume processes. Cheers, Federico Reghenzani 2015-04-10 16:58 GMT+02:00 Ralph Castain : > I’m

I’m afraid not. The MPI job would not be very happy to suddenly lose some nodes during execution, and relocating MPI processes during execution is something we don’t currently support. There is work underway to integrate the RM more fully into that procedure so it could tell the MPI job to chec

The RM can ask for deallocation of some nodes? For example, mpirun asks to the RM which resources are available (let node1, node2, node3) and spawns orted in the nodes. After some time during the elaboration, can the RM ask to deassign node3 or reassign jobs on node3 to node4? Cheers, Federico R

Hi everyone, I'm an italian M.Sc. student in Computer Engineering at Politecnico di Milano. My team and I are trying to integrate OpenMPI with a real time resource manager written by a group of students named BBQ ( http://bosp.dei.polimi.it/ ). We are encountering some troubles, though. Our main
