I'm having difficulty with running a simple hello world OpenMPI
program over Myrinet gm interconnect - please see the log at the end
of this email. The error is tripped by a call to the function
gm_global_id_to_node_id(
gm_btl->port,
gm_endpoint->endpoint_addr.global_id,
&gm_endpoint->endpoint_addr.node_id))
My hardware setup is identical to the one described here:
http://www.open-mpi.org/community/lists/users/2007/02/2577.php
and I'm using the latest stable release - OpenMPI 1.1.4. Has anybody
encountered this error before? Google returns nothing on it...
What version of GM are you running? And are you sure that gm_board_info
shows all the nodes that are listed in your machine file? Could you send
a copy of your gm_board_info output , please? A mismatch between the list
of nodes actually configured onto the Myrinet fabric and the machine file is
a common source of errors like this. The mismatch could be caused by cable
failure or other mapping issues.
Why GM instead of MX, by the way?
thanks!
