[mpich-discuss] MPICH2 Support On Windows HPC Server 2008

[Jayesh Krishna]

Hi,
 We haven't tested the mpiexec delegate feature with Win Srv 2008 domain
controller.
 So are you able to run mpiexec with delegate option (without specifying
"host" option) from a node registered with DC ?
 
Regards,
Jayesh

I have tried all these.  It appears to be related to the win2008 domain
controller.  Has it been tested in this config?

Hi,
 Can you run hostname without specifying "-hosts" (mpiexec -delegate -n 1
hostname) ? Also make sure that you are running mpiexec using delegation
from a node with SMPD Service registered (Run "mpiexec -delegate -n 1
hostname" from a node where you executed "smpd -register_spn").
 Did you get any errors when registering SMPD Service Principal Name (smpd
-register_spn)? Try removing the principal name and registering it again
to verify (smpd -remove_spn ; smpd -register_spn).

Regards,
Jayesh

All,

I have attempted to get MPICH2 1.08 and 1.1 to work on Windows and receive
the following error when performing the following command:

C:\Program Files\MPICH2\bin>mpiexec -delegate -hosts 1
central2.itlab.platform.com hostname

GetGC failed 0x1

DsMakeSpn(mpich2_smpd, central2.itlab.platform.com, 8676) failed: The
parameter is incorrect.

unable to lookup the smpd Service Principal Name.

unable to initialize an sspi context command.

mpiexec aborting job...

C:\Program Files\MPICH2\bin>

I am absolutely certain that I installed smpd using the following command,
and it was successful.

smpd -register_spn

Any help would be appreciated.

Regards,
