[MPICH] MPICH2 with MS Vista

[Brian Andrus]

Jayesh,

No luck. I uninstalled MPICH2, ensured the entry for it was not listed 
in the manage computer->services section and rebooted. I ran the 
installer, used the default passphrase and rebooted after it said it was 
successfully installed.
Then I opened a command window and ran:
    "\Program Files\MPICH2\bin\mpiexec.exe" -n 1 dir
It asks for a passphrase and I get an error:
-----------------------------
Please specify an authentication passphrase for smpd:
Unable to connect to 'Brian-PC:8676',
sock error: generic socket failure, error stack:
MPIDU_Sock_post_connect(1228): unable to connect to Brian-PC on port 
8676, exhausted all endpoints (errno -1)
MPIDU_Sock_post_connect(1275): unable to connect to Brian-PC on port 
8676, No connection could be made because the target machine actively 
refused it. (errno 10061)
-----------------------------

I look at the manage computer->services and MPICH2 is not listed. It 
does not install the smpd service successfully, I think. The only way I 
have been able to see it installed is when I open a command window using 
administrator privileges and running:
    "\Program Files\MPICH2\bin\smpd.exe" -install

I tried starting the service:
-----------------------------
C:\Users\Brian>"\Program Files\MPICH2\bin\smpd.exe" -start
OpenSCManager failed:
Access is denied. (error 5)
-----------------------------

So I tried starting it from an admin console:
----------------------------
C:\Windows\system32>"\Program Files\MPICH2\bin\smpd.exe" -start
OpenService failed:
The specified service does not exist as an installed service. (error 1060)
----------------------------


It seems the installer is not installing the service as would be 
expected under Windows Vista Home Ultimate.
At least not on my new Dell XPS 410.

I can force the install using smpd.exe -install, but I am still unable 
to use wmpiexec (I am able to use mpiexec somewhat).
