An API for the Process Manager Component Meeting at Argonne June 5-6, 2003

Argonne National Laboratory + University of Chicago2 Schematic of Process Management Component in Context QMPM MPD’s mpdrun XML file mpiexec (MPI Standard args) Brett’s job submission language interactive simple scripts using SSS XML SSS Components application processes SSS XML “Official” SSS side Prototype MPD-based implementation side EM SD PM Sched NSM

Argonne National Laboratory + University of Chicago3 How should we proceed? Proposal: voting should actually be on an explanatory document that includes Descriptions – text and motivations Examples – for each type of message, both simple and complicated Details – XML schemas What follows is just input to this process

Argonne National Laboratory + University of Chicago4 The Process Manager Interface The “other end” of interfaces to other components Service Directory Event Manager The commands supported, currently tested by interaction with both the SSS Queue Manager and standalone interactive scripts Create-process-group Kill-process-group Signal-process-group Get-process-group-info Del-process-group-info Checkpoint-process-group

Argonne National Laboratory + University of Chicago5 Some Examples - 1 <create-process-group submitter='desai' totalprocs='32’ output='discard'> <process-spec exec='/bin/foo' cwd='/etc' path='/bin:/usr/sbin‘ range='1-32' co-process='tv-server'> node1 node2 yields:

Argonne National Laboratory + University of Chicago6 Some Examples - 2 yields: <process-spec cwd="/home/desai/dev/sss/clients” exec="/bin/hostname" path="/opt/bin:/home/desai/bin:/opt/bin:/usr/local/bin: /usr/bin:/bin:/usr/bin/X11:/usr/games"/> topaz topaz

Argonne National Laboratory + University of Chicago7 Some Examples - 3 Things like signal and kill process group work the same: yields
