OK, got this.

No firewall nor hosts.xxx.  The problem was from wrong mode set on rsh/rlogin on 
exec nodes (I had played with those following some hints for qrsh problem 
solving on the SGE FAQ, which probably messed up everything).

MPI jobs can now run with qrsh... CPU time displayed by "qstat -ext" is no 
longer 0... but it corresponds to a single cpu!

This job started about 12 minutes earlier, and runs on 2 cpus.  Shouldn't the 
displayed "cpu" be the sum of all cpu times or is this the correct behavior?

Thks for your input
