AFAIK IntelMPI is based on MPICH2, hence this might help:


If you have a Tight Integration of your parallel apps, you can  
disable rsh/telnet in /etc/xinet.d/... completely and limit ssh to  
admin staff by adding a line "AllowUsers gardias" or so to /etc/ssh/ 
sshd_config. If you want to use qlogin or qrsh for interactive  
queues, the rshd and telnet server daemons must be installed on the  
nodes, but SGE will start them on its own for each request.
