Hi All,
I am new to openmpi and have encountered an issue using pre-release 1.5rc5,
for a simple mpi code (see attached). In this test, nodes 1 to n sends out
a random number to node 0, node 0 sums all numbers received.
This code works fine on 1 machine with any number of nodes, and on 3
machines
1.5rc5. It only exists in the developer's trunk at this
> time. Check to ensure you have the right paths set, blow away the install
> area (in case you have multiple versions installed on top of each other),
