Hello,
I am new using MPI. I want to run a simple program (I enclose the program) in 2
different computers. I have installed MPI in both computers. I have compiled
the program using:
mpiCC -o PruebaSumaParalela.out PruebaSumaParalela.cpp
I have copied the executable PruebaSumaParalela.out to
Hello Sofia and list
I am not a C++ person, I must say.
However, I noticed that you wrote the program in C++,
compiled it with the mpiCC (C++) compiler wrapper,
but your MPI calls are written with the MPI C binding syntax,
not the MPI C++ binding syntax.
E.g. :
MPI_Send(&sum,1,MPI_INT,0,1,MPI_C
PI Users"

Sofia,
I took your program and actually ran it successfully on my systems using
Open MPI r19400.
/local ./PruebaSumaParalela.out
Thanks again.

Hello Terry,
Yes, "edu" is the user and 10.4.5.126 is the IP address. Because both
computers have different usernames, I think that I should write the username
otherwise it does not work. In fact, on the computer 10.4.5.123 I write:
mpirun -np 2 --host 10.4.5.123,edu@10.4.5.126 --prefix /usr/

Turns out
routing problem since you are able to reach each
node via ssh. Is there someone else on the list that might want to lend
a hand here? I feel like I am missing something obvious going on here.

The problem is the WiFi connection!
We were connecting the computers using WiFi, we have changed to a cable
connection and the program is working.
It seems that the port that MPI_Send and MPI_Recv use is closed.
Do you know which port use these commands?
