Hello. This may be a usage issue, but we did not have this problem with version 1.0.2.
When starting a parallel job (using TCP) with mpirun, the following message is repeated many times:
[devi01:24440] mca_oob_tcp_accept: accept() failed with errno 9. [devi01:24440] mca_oob_tcp_accept: accept() failed with errno 9. [devi01:24440] mca_oob_tcp_accept: accept() failed with errno 9. [devi01:24440] mca_oob_tcp_accept: accept() failed with errno 9. [devi01:24440] mca_oob_tcp_accept: accept() failed with errno 9. [devi01:24440] mca_oob_tcp_accept: accept() failed with errno 9. : The job is started with the following command:mpirun --prefix <path_to_openmpi> --x LD_LIBRARY_PATH --mca btl sm,self,tcp --np 2 --host devi01 <program_name>
(note: <path_to_openmpi> and <program_name> are not literal)
ompi_info gives the following output:

-----------
The problem happens regardless if only a local node is involved or if
remote nodes are involved.
Any ideas what the issue is? Again, no problems like this with 1.0.2.
Thanks,
