[OMPI users] Connection Errors: Socket is not connected (57) but works for a one messages to each place at first. Works on machine order.

2011-03-05 Thread atexannamedbob


Dear Open-mpi users,
Currently we are running on 4 imacs 10.5.8 all identical and all on the same 
network using MPI version 1.4.1.
We get an error that we cannot seem to find any help on. 
Sometimes we get the error Socket Connection (79)
[30451,1],1][btl_tcp_endpoint.c:298:mca_btl_tcp_endpoint_send_blocking] send() 
failed: Socket is not connected (57)
The strangest thing is the error only happens when we run with certain machines 
in a certain order.


ECHO $Path /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/texbin

mpicc -m64 -lpthread -w -lm -std="c99" inc/*.h lib/*.c -o dispatcher

The strange issues all dispatchers are able to send a one small message  to 
each other before this error occurs.
Does not work:
mpirun -H juhu,hama -n 2 dispatcher
mpirun -H hama,juhu -n 2 dispatcher
mpirun -H hama,tuvalu -n 2 dispatchermpirun -H juhu,tuvalu -n 2 
dispatcherWorks: 
mpirun -H tuvalu,juhu -n 2 dispatchermpirun -H tuvalu,hama -n 2 dispatcher
Dispatcher is a multithreaded application that sends messages to other 
dispatchers.

This was fixed with 
--mca btl_tcp_if_exclude lo,eth0,vmnet0,vmnet1,vmnet8.
The machines were trying to connect through virtual connections on the machine.
Thanks!
