RE: [mpich-discuss] MPICH2 Support On Windows HPC Server
2008<BR><BR>Hi,<BR> 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").<BR> 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).<BR><BR>Regards,<BR>Jayesh<BR><BR><BR>
