Do you know of current examples of such "environments" (clusters)? SSE
was first added to the Pentium III chips in 1999. Wikipedia says that
"many scientific applications refuse to run unless the CPU supports SSE2
or SSE3." Does anybody really have a system that they want to run Amber on
that has "no" support for SSE instructions?
