[mpich-discuss] running mpich2 on windows 7

[Jayesh Krishna]

Bruce,
 It looks like your MPICH2 installation did not complete successfully (Since you are requested the passphrase each time you run a job).
 I would recommend the following,

# Uninstall your existing version of MPICH2 (Add/Remove Programs)
# Install MPICH2 following the instructions in Section 9.4 (NOT 9.1) of the "MPICH2 Installer's guide" (available at http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=docs)
# Try running a simple job ("mpiexec -n 2 hostname") and when prompted for your username/password enter a valid Windows username/password.

 Let us know if it works.

Regards,
Jayesh

Robert. 



Can you provide more details on how to setup through wmpiconfig.exe and wmpiregister.exe? 



Here is what I did: 

1. I ran wmpiregister.exe first to provide user account name and password 

2. Click register, then OK 

3. Open wmpiconfig.exe, saw the host 

4. Not sure what to set, so decided to use all defaults. 

5. Click apply all 

6. Open wmpiexec.exe 

7. Loa d the application cpi.exe, use 1 processor 

8. Click the execute 

9. Saw the following message: 

Error: No smpd passphrase specified through the registry or .smpd file, exiting. 



What I have missed? 



Thanks, 

Bruce

Hi, 



I am new to MPICH2. I have installed the software as administer, then I try to run the example. Here is what I did: 



1. %smpd –start 

2. %mpiexec –n 2 cpi.exe 



Each time when I use only one processor, every think worked. But as long as I use more than one processor, after entering pass phrase, it will be stuck in there forever. Then, I have to kill the job. Can someone tell me if I have missed any setup steps? I am running on a multicore laptop with windows 7 operating system. 



Many thanks. 

Bruce Xu
