Squeezing the most out of an algorithm in CRAY FORTRAN
Jack J. Dongarra, Stanley C. Eisenstat · ACM Transactions on Mathematical Software · 1984
This paper describes a technique for achieving supervector performance on a CRAY-1 in a purely FORTRAN environment {i.e., without resorting to assembler language).The technique can be applied to a wide variety of algorithms m hnear algebra, and is beneficial m other architectural settings.
