Solution to Question 4
Choose the Internet Protocol (ip) communications subsystem library
and the high-performance switch (css0) adapter
by setting these two environment variables:
setenv MP_EUILIB ip
setenv MP_EUIDEVICE css0
On CTC's SP the switch adapter (css0) is selected by default,
but we suggest that when running interactively you choose the ip library
for all runs except production runs where timing is significant.
