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.
... and so was Ada.
"connect() to 192.168.X.X failed: No route to host"
suggests that your 192.168.X.X node cannot be
reached by a message sender.
Can you ping back and forth across every pair of nodes?
