The package contains source code, Unix "man" , pages and a manual. To achieve portability, BlockSolve uses , the Chameleon package developed by Bill Gropp and others at , Argonne National Laboratory. BlockSolve has been tested on the , Intel DELTA, the IBM SP series, and a network of Sun , workstations, but can be expected to run without modification , of source code on other architectures. , This file CANNOT be retrieved by email. by Mark Jones email@example.com, Paul Plassmann firstname.lastname@example.org contact email@example.com prec single/double gams d2b4 lang c age research file contrib for a checklist for netlib contributors file dlamch.f for determines double precision machine parameters. gams r1 file fft.f for yet another fft subroutine, this one from Ferziger's text file gn/GN_ReadMe.pdf for The GN (Gauss Newton) algorithm does nonlinear least squares minimization with finite-difference derivatives. , It uses an augmented Gauss-Newton, Levenberg-Marqardt method. , GN README. file gn/GN.FOR for The GN (Gauss Newton) algorithm does nonlinear least squares minimization with finite-difference derivatives. , It uses an augmented Gauss-Newton, Levenberg-Marqardt method. , The Fortran contains 323 executable lines. by Kenneth Klare, Guthrie Miller, February 21, 2013 lang fortran file groups for list of people interested in na at various centers. by Gene Golub, Stanford age old file ickp.tar.z for for checkpointing programs on the Intel iPSC/2 & iPSC/860 by James Plank, Princeton University gams z file instab.tgz for Instab is a software package for automatically detecting instability , in numerical algorithms. Instab implements functional stability analysis, , which uses the relationship between the forward error, the backward error, , and a problem's condition to define a function that estimates a lower bound , on the backward error. The subplex optimization method then maximizes the function. , A numerical algorithm is unstable if the maximization shows that the backward error , can become large. Since numerical algorithms are treated as black boxes, Instab , normally requires little more than an executable version of a numerical algorithm , to determine if it is unstable. by Tom Rowan <firstname.lastname@example.org> lang fortran size 24K file intel/README.txt for README for Intel(R) Decimal Floating-Point Math Library file intel/IntelRDFPMathLib10U1.tar for Intel(R) Decimal Floating-Point Math Library file iqpack for Fortran subroutines for the weights of interpolatory quadratures , the package is an implementation of the method described in , "Calculation of the Weights of Interpolatory Quadratures", , J.
