You can control the port range that mpich will use. See this item in the FAQ

Hi, Thanks, but somehow setting of MPICH_PORT_RANGE variable on the master VM does not propagate. mpiexec still tries to open the port 34781 which is out of the range set by export MPICH_PORT_RANGE=10000:10100 I'm missing sth - not sure what? Jan -------- [cosy11@oswrk210 mpich-3.1]$ echo $MPICH_PORT_RANGE 10000:10100 [cosy11@oswrk210 mpich-3.1]$ mpiexec -f machinefile2 -n 4 ./examples/cpi [proxy:0:[email protected]] HYDU_sock_connect (utils/sock/sock.c:172): unable to connect from "oswrk207.lns.mit.edu" to "198.125.163.210" (Connection timed out) [proxy:0:[email protected]] main (pm/pmiserv/pmip.c:189): unable to connect to server 198.125.163.210 at port 34781 (check for firewalls!)
