Hello everyone,
I am doing an undergraduate level mini project that will demonstrate the
working of and advantages of running a distributed algorithm in a truly
distributed environment, in the form of a Beowulf cluster. For this purpose
I am using LAM as my message passing interface. However, I am facing a
problem while trying to test the set up with the hello world program. I was
able to set up NFS properly, and am also able to boot using lamboot. I
compiled the hello.c program with the mpicc option, copied the output file
into the directory shared by nfs, and then used the following command to
run -
mpirun n0-2 hello.o
I get an error saying that on atleast one of the nodes started by mpirun,
MPI_INIT wasn't initialized.
My head node(my personal laptop) is a x86_64 architecture based Fedora 12
system, and the rest of my slave nodes(lab computers) are x86 arch Fedora
13 systems. All systems are running the same version of Lam-Mpi 7.1.4.
Could anyone tell me as to where I might be going wrong?
Thank you very much.
Regards,
Saahil
