Resolving The Problem
In LAM/MPI, how do I specify which interconect to use at runtime?
Here is the instruction for specifying the interconnect at runtime.
Assume here that lam-mpi was compiled with ib and tcp support.
To use the IB interconnect :
mpirun -np number_of_nodes -ssi rpi ib ./your_application
To use TCP :
mpirun -np number_of_nodes -ssi rpi tcp ./your_application
