[MPICH] MPICH2 with MS Vista

[Brian Andrus]

I am trying to get MPICH2 working all around with MS Vista. I have 
installed it and I can get a simple hello world to run in the console, 
but I would like to use wmpiexec to run things too. Unfortunately, every 
time I try to run my hello world, I get an error:

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


When I run wmpiconfig and try to scan hosts, I get:
Please specify an authentication passphrase for smpd: 1.0.6

I run wmpiregister and use my logged in username/password, which seems 
to register (wmpiconfig runs this automatically if there is no 
account/pass in the registry).

I noticed a few things:
1) I cannot run the installer as an administrator (the option isn't 
there when I right click on a .msi file)
2) After the install, I needed to open a console administrator and then 
run "smpd.exe -install" to get the MPICH2 process manager service  
registered, otherwise it would not show up under the services.
3) As a normal user, I can run my hello world from a command windows, if 
I have added a user/password using wmpiregister. To do so, I have to 
just hit return when it asks for a passphrase.

Please specify an authentication passphrase for smpd:
Hello World from process 0 on Brian-PC

I used MS Visual C++ express 2008 to create my hello world program. I 
did need to set up a couple paths to get the mpi.h libraries included so 
it would compile and link, but it seems to be working and generating 
executable code.
This is all on a fresh Dell with Vista Home Ultimate installed.

Any ideas what I am missing to get wmpiexec to work?

Thanks in advance,
