 Great ! 
 You are right, the "-register_spn" option works only for windows systems. You can try registering the username/password with mpiexec on the windows machine (mpiexec -register) and launch your jobs from the windows machine.
 Meanwhile, if you are having problems using MPICH2 1.3a1 we would like to hear about it. Please send us more information regarding the crash.

Eureka! I had forgotten to recompile my program after recompiling MPICH2. Also discovered that it crashes with 1.3a1 but works fine with 1.2.1p1. I am now able to run my application between all three types of nodes. However, I'm still annoyed by having to enter the password for the Windows node. Is there a way to make that passwordless when launching mpiexec from the CentOS box? The register_spn stuff would seem to only apply to Windows. 

Thanks!

Hi,
 Good to know cpi is working.

# Did you recompile your target application after recompiling MPICH2 (with ch3:sock) ?
# Can you try running simple MPI programs (smallest possible) to narrow down on the problem ?
