[Mpi-forum] I can not make MPI recognizes a dual core

[Jeff Squyres (jsquyres)]

This list is more about the standards body for MPI, not so much general user questions. 

Your question is better posted to whatever the relevant support mechanism is for your MPI implementation. For example, if you're using Open MPI or MPICH, there are public mailing lists when you can send your question. If you're using a vendor MPI implementation, you might want to try your support channel with them. 

Good luck!

Subject: [Mpi-forum] I can not make MPI recognizes a dual core

Hello. I am writing my first program in MPI. I write the sentences:
...
int id;
MPI_Comm_rank (MPI_COMM_WORLD, & id);
if (id == 0)
/ * Master task * /
(
...
)
else
/ * Worker task * /
(
...
)
And I write other sentences. The issue is that it does not recognize a
DualCore processor, and takes the machine as it only has one
processor, indeed, never enters the else.
I would appreciate very much any help.
Sincerely,
Yessica Brinkmann
