Opteron leads 64-bit revolution

"For instance, the University of Utah's Center for High-Performance
Computing in Salt Lake City has been recompiling its 32-bit
applications to 64 bits, using a compiler developed by PathScale Inc.
in Sunnyvale, Calif. This speeds up processing time by 10% to 20%,
depending on the application-a significant gain for applications that
run over many hours, said Martin Cuma, who is in charge of scientific
application programming at the center."
