[MPICH] MPICH2 with MS Vista

[Jayesh Krishna]

 Hi,
  The smpd passphrase is the passphrase that the user specifies during the
MPICH2 installation process (By default the passphrase is set to "behappy"
and the user has the option of changing it. The user is prompted for the
same during the MPICH2 installation).
  You don't have to run "smpd.exe -install" to get smpd running on your
system. During a successful installation this is done for you by the
installer.
  I would recommend that you re-install MPICH2 on your system (after
uninstalling the existing version of MPICH2). Please try rebooting your
system before running mpiexec. Initially try running some simple command
like "mpiexec -n 1 dir". Then try running "mpiexec -n 2 cpi.exe" (cpi.exe is
provided with 32-bit version of MPICH2 in <INSTALL-DIR>\MPICH2\examples
directory)

Regards,
Jayesh

Subject: [MPICH] MPICH2 with MS Vista

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
Number of Processes: 2
Hello World from process 1 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,

Brian Andrus
