Actually, I was talking specifically about configuration at build time. I realize there are trade-offs here, and suspect we can find a common ground. The problem with using the options Jeff described is that they require knowledge on the part of the builder as to what environments have had their

Hello All, In the recent few weeks I implemented ticket 1023 (https://svn.open-mpi.org/trac/ompi/ticket/1023 ). In a few words, the purpose of ticket 1023 is to expand the hostfile syntax to precisely specify slot location (in terms of virtual

As I understood our original discussions, this would move responsibility for mapping rank to processor back into the orted - is that still true? Reason I ask is to again clarify for people if we are doing so as it (a) impacts those systems that don't use our orteds (e.g., will affinity still work

Yo all I have upgraded the support for Bproc on the Open MPI trunk as of r15328. We now support Bproc environments that do not utilize resource managers - in these cases, we will allow the user to launch on all nodes upon which they have execution authorities. Please note that, if you login to

Hi Ralph, The responsibility for mapping rank to processor is in the ODLS component. I didn't touch the orted code. If you doesn't use orted - you steel use the ODLS component (like ODLS bproc). Any way you mast have a component in the end machine that builds the orte_odls_child_t structure from

2007-07-10 Thread Ralph H Castain
Ah, I see the problem. I think you have misunderstood the ODLS framework. The ODLS is the "Orte Daemon Launch Subsystem" and is used by the orted to launch the local procs. Mpirun also accesses the ODLS, but only to construct the add_procs message that gets sent to the daemons. The problem is,

Hi Ralph, My answer has 2 parts: 1. I'm not familiar with bproc but I assume that when working with bproc there is a component that reads the RMAPS information somehow and launches the local process. In that case you can add the affinity there according the slot_list (new member in the map) from
