Subject: [OMPI users] Trouble with Sending Multiple messages to the Same Machine

Hi guys ☺! I'm working with a simple "Hello, World" MPI program that has one master and is sending one message to each worker, receives a message back from each of the workers, and re-sends a new message. This unfortunately is not working :(. When the master only sends one message to each worker, and then receives it, it is working fine, but there are problems with sending more than one message to each worker. When it happens, it prints the error: [[401,1],0][../../../../../openmpi-1.6.3/ompi/mca/btl/tcp/btl_tcp_endpoint.c:638:mca_btl_tcp_endpoint_complete_connect] connect() to 192.168.X.X failed: No route to host (113) I'm wondering how I can go about fixing this. This program is running across multiple Linux nodes, by the way :).  BTW, I'm a girl.
