[TUHS] benchmark

[steve jenkin via TUHS]

In the absence of responses, 
	John Lions started a quick benchmark using ‘dc’.

Could be done at trade shows on many machines, if there was an open console.

I saw a long list of these benchmarks in 1986 - maybe 100 m/c.

Ken McDonnell did a lot of work on benchmarking.
Pyramid hired him to the USA.

Someone who knows the TUHS site / Doco might have a better answer for you.

BENCHMARKING SUITES

The following benchmark suites are available. 
In some cases, I haven't yet determined how to obtain the item.

* Monash University (MUSBUS) benchmark suite, which has been posted to Usenet in comp.sources.unix. 
This suite was authored by Ken J. McDonnell, now with Pyramid Technology: kenj at pyrnova.pyramid.com. 
It may be obtained from uunet.uu.net via anonymous ftp, or via the archive server at uunet!netlib. 
The 5.0 version is in comp.sources.unix/volume11/musbus;

Tim Long: Quick Benchmarks of the Machines on Display

A simple cpu-bound benchmark was run on each of the machines on display.

The benchmark was "echo 99k2vp8opq I /bin/time dc > /dev/null’.
 It uses dc (the desk calculator) to calculate the square root of 2 to 99 decimal places,
and to "print" the result in decimal and then in octal.
