After a patch or two I finally managed to get GCC 1.34 to compile a rather large floating point intensive code for the Alliant. GCC outperforms PCC as is usual, but the Allian FX/C compiler producing code that is a little more than twice as fast as GCC code. I presume that the difference is mostly pipeline scheduling that GCC lacks any knowledge of. I remember someone setting out to create a portable pipeline scheduler for GCC, the Alliant might be a good test target for this. Is the news software incompatible with your mailer too? brooks@maddog.llnl.gov, brooks@maddog.uucp, uunet!maddog.llnl.gov!brooks
