Algorithm 814: Fortran 90 software for floating-point multiple precision arithmetic, gamma and related functions
David M. Smith
Pages: 377-387
DOI: 10.1145/504210.504211
A collection of Fortran-90 routines for evaluating the gamma function and related functions using the FM multiple-precision arithmetic package.

Analysis and comparison of two general sparse solvers for distributed memory computers
Patrick R. Amestoy, Iain S. Duff, Jean-Yves L'excellent, Xiaoye S. Li
Pages: 388-421
DOI: 10.1145/504210.504212
This paper provides a comprehensive study and comparison of two state-of-the-art direct solvers for large sparse sets of linear equations on large-scale distributed-memory computers. One is a multifrontal solver called MUMPS, the other is a...

FLAME: Formal Linear Algebra Methods Environment
John A. Gunnels, Fred G. Gustavson, Greg M. Henry, Robert A. van de Geijn
Pages: 422-455
DOI: 10.1145/504210.504213
Since the advent of high-performance distributed-memory parallel computing, the need for intelligible code has become ever greater. The development and maintenance of libraries for these architectures is simply too complex to be amenable to...

Algorithm 815: FORTRAN subroutines for computing approximate solutions of feedback set problems using GRASP
Paola Festa, Panos M. Pardalos, Mauricio G. C. Resende
Pages: 456-464
DOI: 10.1145/504210.504214
We propose FORTRAN subroutines for approximately solving the feedback vertex and arc set problems on directed graphs using a Greedy Randomized Adaptive Search Procedure (GRASP). Implementation and usage of the package is outlined and computational...
