Hello. I am using MPICH2. 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 am using windows 7 and I execute at windows comman line mpiexec -np
2 my_program.exe
at the MPICH2\bin directory.
The system response to me:
Please specify an authentication passphrase for smpd:
And then I write the authentication passphrase that I write on the
MPICH instalation and the system response to me: Error while connectig
to host, No se puede establecer una conexión ya
que el equipo de destino denegó expresamente dicha conexión (10061)
Connect on sock(host=User-PC, port=8676) failed, exhaused all end
points Unable to connect to 'User-PC:8678', sock error: Error = -1
When I write smpd -start the system response to me:
OpenSCManager failed: Denied access. (error 5)
I would appreciate very much any help.
Sincerely,
Yessica Brinkmann
