hi ,
i am working on a project that involves parallel processing so i
obviously need to use lam...my project involves running a C source code on 4
processors with each processor exchanging info from one another using
MPI_send and MPI_Recv calls... i was told that i can simulate a 4 processor
environment using lam by setting the same hostname 4 times in the hostfile ,
then running lamboot on the processor and the code should work in parallel
by giving the ranks 0,1,2,3 to the single processor...
Here is where i am facing the problem.... the code only executes the rank
0's statements and halts when the MPI_Recv call by rank 0 is made giving the
error:
Rank(0,MPI_COMM_WORLD) : call stack for LAM
Rank(0,MPI_COMM_WORLD) : MPI_Recv()
Rank(0,MPI_COMM_WORLD) : main()
and goes back to the shell. its not executing the other rank's(1,2,3)
statements at all.
is there anywhere that i am going wrong ?? what should i do ?? please
help ! you are my last hope.
