Here is an updated list of xfroot fractal-points/processor_second
measured on various clients. The number, a count of trips/second
through the 8 line "hopalong" loop in xfroot, is a rough index of scalar
double-precision floating point uniprocessor speed.

I would appreciate hearing about measurements on other clients, or results
differing significantly from those above. To perform your own
xfroot micro-benchmark:
1. Get xfroot/part01 (V5-I3) and xfroot/patch1(V5-I7) from
comp.sources.x.
2. Install xfroot on the client to be tested, taking care
that you have verified the definition of HZ in xfroot.c.
(See the README.)
3. Make the following two runs:
xfroot -a 0.1 -b 0.1 -c 0.1 (lower bound)
xfroot -a 3000 -b 3000 -c 3000 (upper bound)

A few notes on the results: gcc enhancements are due to inline code for
sqrt and fabs. The three top Convex C2 measurements use compilers/libraries
that exploit the C2 hardware sqrt. It pays to shop around for the best
compiler/options/libraries available for your floating point intensive code.

The third posting indeed transposed two digits in the machine name for
xfroot timings reported for HP9000/835CHX. Also, a note attributing improved
^^
timings reported for the HP9000/330 to an improved compiler with
HP-UX 6.5 was inadvertently omitted from this posting.

Here is the 4th updated list of xfroot fractal-points/processor_second
measured on various clients. The number, a count of trips/second
through the 9 line "hopalong" loop in xfroot, is a rough index of scalar
double-precision floating point uniprocessor speed. The lower number
represents a case where nearly all points are in-range and thus require
additional integer arithmetic, bit manipulation, and memory accesses to
record the point. The higher number reflects a case when most points are
out of range and most time is spent in floating point arithmetic. The
numbers in parentheses are VAX 780 equivalents. "*" indicates values for
a single processor. New items since the last posting are marked with ">".

A few notes on the results: the Cray scc compiler uses the same backend
as their Fortran compiler. gcc enhancements are due to inline code for
sqrt and fabs. The three top Convex C2 measurements use compilers/libraries
that exploit the C2 hardware sqrt. It pays to shop around for the best
compiler/options/libraries available for your floating point intensive code.

for sharing their results.
I would appreciate hearing about measurements on other clients, or results
differing significantly from those above. To perform your own:
1. Get xfroot/part01 (V5-I3) and xfroot/patch1(V5-I7) from
comp.sources.x. These are available via anonymous ftp from
uunet.uu.net. While they will eventually be found there in
comp.sources.x/volume5, as of this writing they are in
comp.sources.x/new/890924.0.Z and 890929.0. If you don't
have ftp access to uunet.uu.net, I will be happy to mail
a copy (~700 lines.)
2. Install xfroot on the client to be tested, taking care
that you have verified the definition of HZ in xfroot.c.
(See the README.)
3. Make the following two runs:
xfroot -a 0.1 -b 0.1 -c 0.1 (lower bound)
xfroot -a 3000 -b 3000 -c 3000 (upper bound)

Here is the 6th updated list of xfroot fractal-points/processor_second
measured on various clients. The number, a count of trips/second
through the 9 line "hopalong" loop in xfroot, is a rough index of scalar
double-precision floating point uniprocessor speed. The lower number
represents a case where nearly all points are in-range and thus require
additional integer arithmetic, bit manipulation, and memory accesses to
record the point. The higher number reflects a case when most points are
out of range and most time is spent in floating point arithmetic.

A few notes on the results:
o The top DN10000 timings used the PRISM 6.7(359) compiler with
the following options: -opt 4 -cpu a88k -def sqrt=_builtin_sqrt
-def fabs=_builtin_fabs.
o Two SPARCstation results using sqrt.i1 and libm.i1 were reported.
The only difference appeared to be that the faster one was compiled
and linked in one step. Can anyone enlighten us on this?
o The Cray scc compiler uses the same backend as their Fortran.
o gcc enhancements are due to inline code for sqrt & fabs.
o Strikingly different results for the same system show that it pays to
shop around for the best compiler/options/libraries available.

I would appreciate hearing about measurements on other clients, or results
differing significantly from those above. To perform your own:
1. Get xfroot/part01 (V5-I3) and xfroot/patch1(V5-I7) from
comp.sources.x. These are available via anonymous ftp from
uunet.uu.net. While they will eventually be found there in
comp.sources.x/volume5, as of this writing they are in
comp.sources.x/new/890924.0.Z and 890929.0. If you don't
have ftp access to uunet.uu.net, I will be happy to mail
a copy (~700 lines.)
2. Install xfroot on the client to be tested, taking care
that you have verified the definition of HZ in xfroot.c.
(See the README.)
3. Make the following two runs:
xfroot -a 0.1 -b 0.1 -c 0.1 (lower bound)
xfroot -a 3000 -b 3000 -c 3000 (upper bound)

The 9th update of xfroot timings is available. These timings provide a rough
index of scalar double-precision floating point uniprocessor speed on dozens
of X clients spanning three orders of magnitude in processor speed. This update
has new or revised timings for the Stardent 3000, Titan, and GS2000, Convex C2
with "ESP" feature, MIPS R2000, IBM RT135/EAFPA, ISI V24K, and Vax 750. The
timings are available:
1. Via anonymous ftp to uxc.cso.uiuc.edu in pub/xfroot/timings
2. Via email request to ejk@ux1.cso.uiuc.edu. Indicate if you wish to
