Hello,

I have the following error when I run a job:

It seems that there is no lamd running on the host cbuach.

This indicates that the LAM/MPI runtime environment is not operating.
The LAM/MPI runtime environment is necessary for MPI programs to run
(the MPI program tired to invoke the "MPI_Init" function).

Please run the "lamboot" command the start the LAM/MPI runtime
environment.  See the LAM/MPI documentation for how to invoke
"lamboot" across multiple machines.

I added the environment variables in my .bashrc:

PATH=/usr/local/openmpi-1.3.2/bin:$PATH
export PATH
LD_LIBRARY_PATH=/usr/local/openmpi-1.3.2/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH

I tried defining directly the path of the mpirun on the open-mpi folder:

/usr/local/openmpi-1.3.2/bin/mpirun --host ubuntu-frontend -np 8  mb -i  batch_flavescens.txt>log.txt &

but doesn't work, I hope any help to fix this problem.

this is the ompi_info output:
