Hi all,
I am currently developping a paralell application with LAM/MPI and
everything used to be fine. However, since yesterday I cannot work any
more with the system.
I tried to isolate the problem so I tried to check if MPI works with a
simple paralell "Hello world!". I'm getting the following error:
magonzalez_at_baobab:~/StageVerano/MultMatrices/MPI/Ver1$ mpirun -np 3 ./hello
-----------------------------------------------------------------------------
The selected RPI failed to initialize during MPI_INIT. This is a
fatal error; I must abort.
This occurred on host n2 (n1).
The PID of failed process was 12909 (MPI_COMM_WORLD rank: 2)
I also tried with only 2 cluster nodes and there's is no problem
but... there isn't any output! (before THERE WAS an output):
magonzalez_at_baobab:~/StageVerano/MultMatrices/MPI/Ver1$ mpirun -np 2 ./hello
magonzalez_at_baobab:~/StageVerano/MultMatrices/MPI/Ver1$
I have searched the answer for my problem into the list and the
Internet but I found no satisfactory solutions.
I will thank any help :),
