Yes they do. Or at least ours does. The SPARC64/OS, which is based on 2.4 with `extensions' to 64bit, runs code compiled on our Suns under 2.3 and 2.4 with no problems at all. The 64-bit HAL tuned compilers give a significant performance boost compared to the Sun code. -- Phillip Fayers Email: P.Fayers@astro.cf.ac.uk SunAdmin/Support/Programming/Postmaster(TM) Phone: +44 (0)1222 874000 ext 5282 University of Wales, College of Cardiff Fax : +44 (0)1222 874056 Department of Physics and Astronomy WWW : http://www.astro.cf.ac.uk/ P.O.
