Evaluation of ESSL on the SP2

  Michel Roethlisberger, IBM

ESSL (Engineering and Scientific Subroutine Library) is now under evaluation on the SP2. ESSL is a state-of-the art collection of 441 subroutines providing a wide range of mathematical functions for scientific and engineering applications.

It includes computational area like Linear Algebra, Matrix operations, Eigensystem Analysis, Fourier Transform, Sorting and Searching, Interpolation, Numerical Quadrature, Differential Equations and Random Number Generation. It can be called from applications written in Fortran, C and C++ and is tuned for the SP2 processors. Speed-ups over 20 compared to standard CERNLIB routines has already been reported (e.g. for GARFIELD).
