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

Tue May 25 11:18:27 CDT 2010

Hi, Very thanks for your response.
I reinstalled the MPICH2 by the steps that you say to me.
After the installation I try to run a non-MPI program (mpiexec -n 2
hostname) and I have the same error:
I have the output:
Please specify an authentication passphrase for smpd:
I write the authentication passphrase and the system response to me:
Aborting: unable to connect to User-PC
Very thanks.
I will thanks any help.

>> Hi,
>>  This is strange. From the error messages it looks like you don't have admin privileges. Are you able to open an administrative command prompt (Right-click on command prompt icon - select "Run as administrator")?
>>  What is the output when you type "smpd -install" from the admin command prompt (You have to run the command from an administrator command prompt)?
