[OMPI devel] Confusion about slots

send to mpirun? The number of processor sockets, the number of cores or the number of hwthread available? How --map-by and --rank-by affect the spawn policy? Thank you! OFFTOPIC: is someone going to EuroMPI 2016 in September? We will be there to present our migration technique. Cheers, Fed

), but we have a degradation of 50%, and we are sure that is not an overhead due to orteds initialization. Do you have any idea how can multiple orteds influence the processess performance?

[OMPI devel] Remote orted verbosity

Hi! Is there any way to get the output of OPAL_OUTPUT_VERBOSE on remote orted*s*? (or write it to a local file?). We tried with *--mca orte_debug_verbose* but it works only for the local machine (= where mpirun is executed). Cheers, Federico __ Federico Reghenzani M.Eng. Student @ Politecnico

Re: [OMPI devel] Info about ORTE structure

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 &l

Re: [OMPI devel] Info about ORTE structure

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
