We at Gaussian, Inc. agree with this, but in practice it requires a reliable
operating system, and this is definately not the case for Linux/Alpha, and
is questionable for Linux/PPC.

We have an Alphax/Linux machine in house but Linux for Alpha has turned out
to be very, very far from the stable environment Linux is for Intel machines.
For example, there are well-documented and very serious problems linking
large programs which have not yet been resolved. Anyone interested can
subscribe to the Linux/Alpha mailing list and receive a dozen or so examples
PER DAY of things that work under Linux/Intel but not under Linux/Alpha.
When Linux is actually stable for production use on processors other than
Intel, we certainly intend to support Gaussian there.
