./benchmarks/flops, Floating point benchmark to give your MFLOPS rating

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 2.0, Package name: flops-2.0, Maintainer: pkgsrc-users

Flops.c is a 'c' program which attempts to estimate your systems
floating-point 'MFLOPS' rating for the FADD, FSUB, FMUL, and FDIV
operations based on specific 'instruction mixes' (discussed below).
The program provides an estimate of PEAK MFLOPS performance by making
maximal use of register variables with minimal interaction with main
memory. The execution loops are all small so that they will fit in
any cache. Flops.c can be used along with Linpack and the Livermore
kernels (which exercise memory much more extensively) to gain further
insight into the limits of system performance. The flops.c execution
modules include various percent weightings of FDIV's (from 0% to 25%
FDIV's) so that the range of performance can be obtained when using
FDIV's. FDIV's, being computationally more intensive than FADD's or
FMUL's, can impact performance considerably on some systems.

all: migrate homepages from http to https
pkglint -r --network --only "migrate"
As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Add SHA512 digests for distfiles for benchmarks category
Problems found with existing distfile for superpi:
	distfiles/super_pi-20030927/super_pi.tar.gz
No changes were made to the superpi/distinfo file.
Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.
