Delayed AMD64 compiler shows great promise

LAST MONDAY, the Portland Group, which has been working on compilers and other tools that have been optimized for AMD64, should have gone gold with PGI Workstation 5.0, which includes those optimizations, but instead announced a delay until on or before July 7.
For its unreleased product, the Portland Group is making performance improvements claims averaging 34% over PGI Workstation 4.1 on several industry standard benchmarks. Now that is a huge hike in performance from just compiler optimizations. The SPEC2000 floating point benchmark shows one Opteron result improving by almost 375%.

I can't predict the performance improvement gains that we'll see from recompiled applications, but they should be good. As Douglas Miles, director of the Portland Laboratory, has said :

"Porting our software, which represents well over a half million lines of code, from 32-bit X86 processor-based systems to 64-bit AMD Opteron processor-based systems has been very straightforward. We have also been extremely impressed with the performance of both legacy 32-bit applications and 64-bit applications re-compiled to take advantage of the new features of the AMD Opteron processor."
