Subject: [OMPI users] Openmpi on Heterogeneous environment
From: Yogesh Aher (aher.yogesh_at_[hidden])

Dear Open-mpi users,

I have installed openmpi on 2 different machines with different
architectures (INTEL and x86_64) separately (command: ./configure
--enable-heterogeneous). Compiled executables of the same code for these 2
arch. Kept these executables on individual machines. Prepared a hostfile
containing the names of those 2 machines.
Now, when I want to execute the code (giving command - ./mpirun -hostfile
machines executable), it doesn't work, giving error message:

MPI_ABORT was invoked on rank 2 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
mpirun has exited due to process rank 2 with PID 1712 on
node exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here)

When I keep only one machine-name in the hostfile, then the execution works

Will anybody please guide me to run the program on heterogeneous environment
using mpirun!

Thanking you,
