I have a large fortran code processing data (weather forecast). It runs ok with smaller dataset, but on larger dataset I get some errors I've never seen before:
node061:05144] [[55141,0],11]->[[55141,0],0] mca_oob_tcp_msg_send_handler: writev failed: Bad file descriptor (9) [sd = 9]
[node061:05144] [[55141,0],11] routed:binomial: Connection to lifeline [[55141,0],0] lost
node084:7.0.Non-fatal temporary exhaustion of send tid dma descriptors
(elapsed=43.788s, source LID=0x49/context=11, count=1) (err=0)
I'm using QLogic software version 126.96.36.199.58 (ofed 188.8.131.52, open-mpi 1.4.3).
I'm starting this program with mpirun -mca btl openib,sm,self so I don't really understand what tcp has to do in the first error message.
Also I traced second error message to psm code, but it appears even if i add -mca mtl ^psm to my mpirun arguments. Why?
Any help appreciated.
