[mpich-discuss] [mpich2-dev] I can not make MPI recognizes a dual core

Hi,
 Is the new user, MPI, an admin user ? How did you install MPICH2 for only that user ? I am still surprised that you have to install smpd explicitly (that the installer does not install it for you).
 MPICH2 runtime system requires user credentials to launch an MPI job. Looks like you are logged on as "User-PC\MPI". Try entering the password (for user "User-PC\MPI") without entering the username (When mpiexec prompts for the username just press the enter key).
 I would also recommend getting help from your sysadmin regarding installation of MPICH2 (Or better anyone else in your team who has installed/used MPICH2).

Regards,
Jayesh

Hi, very thanks for your response.
I created a new user called MPI and I reinstalled the MPICH2 only for
this user, and I executed the sentences that you say for me.
When I write
smpd -uninstall
The system response to me:
Stopping MPICH2 Process Manager, Argonne National Lab.
MPICH2 Process Manager, Argonne National Lab stopped.
MPICH2 Process Manager, Argonne National Lab removed.

When I write:
smpd -install -phrase behappy
 The system response to me:
MPICH2 Process Manager, Argonne National Lab installed.

When I write:
smpd -status
 The system response to me:
smpd running on User-PC

When I write:
mpiexec -n 2 hostname
 The system response to me:
User credentials needed to launch processes:
account(domain\user) [User-PC\MPI]:

And at this point I does not how I should write, I try with MPI or
User-PC\MPI, but does not work.
Then the system ask to me for the password:
I write the password that I use for the MPI user, and the system response to me:
Credentials for MPI rejected connecting to User-PC.
Aborting: Unable to connect to User-PC
I think this is because I does not known how I should write when the
system ask to me:
User credentials needed to launch processes:
account(domain\user) [User-PC\MPI]:

I will thanks any help.
