Ralph,
I am not using the TCP BTL, only OPENIB one. Does this change the
number of sockets in use per node, please ?
But I suspect the ORTE daemons are communicating only through TCP
anyway, right ?
Also, is there anybody in the OpenMPI team using an SGI Altix cluster
with a high number

Are you by chance using static ports for the job? Did you run another job just
Bonjour,
Running with OpenMPI 1.4.3 on an SGI Altix cluster with 4096 cores, I got
this error message, right at startup :
mca_oob_tcp_peer_recv_connect_ack: received unexpected process
identifier [[13816,0],209]
and the whole job is going to spin for an undefined period, without
