- This report is intended to be dense with only raw values and occasional
ratios: no data reduction is done, nor any explanation is given, which
implies interpretation and/or judgement of value. However and perhaps because
of this, comments and remarks
Throughout succeeding releases of this report, values for R may have changed:
normally, it's no error but a proof of the permanent improvement process of
every living system. In particular, a same machine may give significantly
different results within this report, or display a not-so-good value (compared
with the ones seen or reported elsewhere): different runs at different times
with different configurations will most likeky give different
results, if simply because many differences may and do occur: new compiler,
compiler version, new optimization technique, new preprocessed source ..., on
the software side, and cache size, bus width ... on the hardware side .
- This benchmark now is frequently used by a large segment of concerned
parties: you will find it included in many internal or public suites such
Suite Synthétique des Benchmarks de l'
(89 & 92) Benchmark Suites ...
- A subset of the best performing executables for each main architecture is available for standalone ready-to-go as-is execution :
as well as the different source versions for recompilation :
- Version 55 of this report gets a new table, a single (last) page
summarizing the TOP FIFTY machines with a new ratio : the
R1996 refers to the 1996 reference machine, a
Sun SPARCstation 10/40 (no cache, Sun SC3 (f77 O4 fast)) . Within the scope and limits of this benchmark, the
of this new reference machine was 1908 , with respect to the old 1978 reference machine, an IBM 370/168-3 (HSMU, Fortran 4.H.extended) .
