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. Mike Frisch Gaussian, Inc.
