That's really very interesting observation! I'm still using v. 1.4 on my cluster but was about to upgrade. Did you submit the bug report to the mp-mpich mailing list or to NT-MPICH authors? Did you get any replies? Please keep us informed.

Regards,
Alexei

>last days, within our 64 bit Windows PC GAMESS cluster of machines, I tried to upgrade the 1.5.0 NT-MPICH interface (owing to reportedly "many many bugs have been fixed"), which was released in the last weeks of 2007. However, I got bad results due to a fail of actual communication among machines. Typical symptoms are the undertaking by the main node of all the PC GAMESS processes which should have been distributed among the nodes and the fall of the rcluma service in the main node. However, the MPICH lib subdir is correctly addressed n the PATH system variable, the cluster manager service is active in every machine and Windows SP2 Firewall is open. Anyway, everything worked fine with 1.4.0 release. Thus I had to downgrade to the previous MPICH release, eventually.
