poe: MPI driver for AIX.
Usage: submit = poe $command ...
Command-line parameters:
-procs $ranks The number of ranks to run. Can also be specified with the MP_PROCS environment variable.
-hostfile $hostfile Name of file containing the list of names of hosts that will run each rank. Can also
be specified with the MP_HOSTFILE environment variable.
Parameters specified by environment variables:
MP_PGMMODEL=spmd Set program model to Single-Program/Multiple-Data.
MP_MSG_API=mpi Specify that MPI is the message-passing protocol to use.
MP_DEVTYPE=ib Use InfiniBand devices for communication.
MP_CLOCK_SOURCE=AIX Retreive time values from the OS.
MP_ADAPTER_USE=shared Determines how the node's adapter should be used (e.g. "shared" for shared between ranks).
MP_EUILIB=us Determines the communication subsystem implementation to use (e.g. "us" for user mode).
MP_EUIDEVICE=sn_single Determines the adapter set to use for message passing (e.g. "sn_single" for one window per task).
MP_EUIDEVICE=sn_all Using "sn_all" causes user-space windows to be striped per task.
MP_SHARED_MEMORY=yes Do not use switch to transmit messages within the same node.
MP_SINGLE_THREAD=yes Skip mutex locking in single-threaded ranks.
MP_WAIT_MODE=poll Poll across blocked threads.
MP_WAIT_MODE=yield Suspend blocked threads.
MP_EAGER_LIMIT=65536 Use rendezvous protocol above this message size.
MP_BUFFER_MEM=67108864 The size of the Early Arrival (EA) buffer that is used by the communication subsystem.
MP_POLLING_INTERVAL=80000000 Length of polling interval, in microseconds.
MP_PULSE=0 The interval at which POE checks the remote nodes to ensure that they are communicating with the home node. Use 0 to disable.
MP_USE_BULK_XFER=yes Use the bulk data transfer mechanism.
MP_BULK_MIN_MSG_SIZE=65536 Use bulk data transfer for messages of at least this many bytes.
MP_STDINMODE=none Tasks will not read input from STDIN.
MP_STDOUTMODE=unordered Determines the formatting of task output.
MP_LABELIO=no Do not label lines of output with the task ID number.
MP_RESD=no Determines whether or not the Partition Manager should connect to the LoadLeveler utility.
MP_CSS_INTERRUPT=no Determines whether or not arriving message packets cause interrupts.
MP_INFOLEVEL=0 Determines the level of message reporting.
MP_PMDLOG=no Determines whether or not diagnostic messages should be logged to a file in /tmp on each of the remote nodes.
MP_PARTITION=64 An identifying number that is the same for all tasks in a job.
NRT_WINDOW_COUNT=1 Set to the number of communication windows used by each task.
