[mpich-discuss] MPI_Comm_accept() / connect() errors

[Blesson Varghese]

Hi,

 

I am running MPI 2.0 on Ubuntu 4.2.4, kernel version 2.6.24.

 

I have been trying to execute the server.c and client.c program provided in
http://www.mpi-forum.org/docs/mpi21-report/node213.htm#Node213, using
accept() and connect() function in MPI. However, the following errors are
generated.

 

[hpcc00:16522] *** An error occurred in MPI_Comm_connect

[hpcc00:16522] *** on communicator MPI_COMM_WORLD

[hpcc00:16522] *** MPI_ERR_INTERN: internal error

[hpcc00:16522] *** MPI_ERRORS_ARE_FATAL (goodbye)

 

I ran the server program as mpirun -np 1 server. This program gave me the
output port as 0.1.0:2000. I used this port name as the command line
argument to execute the client program as mpirun -np 1 client 0.1.1:2000

 

Could you please advice?

 

Many thanks,
Blesson.
