Hi,
I have a 4 processor (4 machine) configuration.
I renamed lab2.c to ring.c and compiled and while running I get this
output:
lamboot -v .lamhosts
LAM 6.3.2/MPI 2 C++ - University of Notre Dame
Executing hboot on n0 (sirius.cs.pdx.edu)...
Executing hboot on n1 (achbia.cs.pdx.edu)...
Executing hboot on n2 (algenib.cs.pdx.edu)...
Executing hboot on n3 (alpheratz.cs.pdx.edu)...

/u/dagav 10:31:46>mpirun -v n0-3 ring
27097 ring running on n0 (o)
15952 ring running on n1
21310 ring running on n2
7622 ring running on n3
Enter the number of times around the ring: 5
Process 0 sending 5 to 1
MPI_Recv: process in local group is dead (rank 0, MPI_COMM_WORLD)
Rank 0: Call stack within LAM:
Rank 0: - MPI_Recv()
Rank 0: - main()
what could be going wrong?
