Hi, I have just install OpenMPI-1.7.1 and cannot get it running.
Here is the error messages: [cmy@gLoginNode1 test_nbc]$ mpirun -n 4 -host gnode100 ./hello [gnode100:31789] Error: unknown option "--tree-spawn" input in flex scanner failed [gLoginNode1:14920] [[62542,0],0] ORTE_ERROR_LOG: A message is attempting to be sent to a process whose contact information is unknown in file rml_oob_send.c at line 362 [gLoginNode1:14920] [[62542,0],0] attempted to send to [[62542,0],1]: tag 15 [gLoginNode1:14920] [[62542,0],0] ORTE_ERROR_LOG: A message is attempting to be sent to a process whose contact information is unknown in file base/grpcomm_base_xcast.c at line 166 I have run it on several nodes, and got the same messages. - Zehan Cui
