GNU PROLOG Benchmarks
			=====================


This directory contains a set of Prolog benchmarks

To compile them with GNU Prolog:

	make

Each benchmark accepts a count (nb of iteration) as command-line argument, e.g:

	zebra 10
	house(yellow,norwegian,fox,water,kools)
	house(blue,ukrainian,horse,tea,chesterfields)
	house(red,english,snails,milk,winstons)
	house(ivory,spanish,dog,orange_juice,lucky_strikes)
	house(green,japanese,zebra,coffee,parliaments)
	17 msec per iter, 10 iters, total time : 170 msec

NB: only the last iteration displays the solution.

Each bench includes the Prolog file common.pl (part recovering the counter
from the command-line and ierating the bench). This file includes itself the
Prolog source hook.pl defining the predicats get_count/1 (recover the count
form the command-line) and get_cpu_time/1 (user time in msec).

This makes it possible to run the benchmarks with different systems (defining
a hook.pl file for each system).

Each sub-directorie (YAP, WAMCC, SICSTUS, CIAO, BINPROLOG, XSB, SWI) contains
3 files:

	MAKE_PROGS: a shell-script building the benchmarks
	MAKE_CLEAN: a shell-script removing build benchmarks
	HOOK.pl: the hook file needed for the corresponding system

To compile the benchmarks with a given system use MAKE_PROGS in the
associated directory (e.g. YAP):

	cd YAP
	MAKE_PROGS   (or MAKE_PROGS BENCH_NAME...)

MAKE_PROGS build the list of benchmarks passed as argument. In none, it
builds all benchmarks described in the file ../PROGS.  Be sure to be in the
sub-directory (cd) before doing MAKE_PROGS.  NB: under SICSTUS, the
compilation mode is byte-code (compactcode), to activate native code
(fastcode) define the environment variable NATIVE.

The build benchmark act like under GNU Prolog, accepting a count as
command-line argument. It is not mandatory to be in sub-directory for the
execution. e.g.:

	~/.../ExamplesPl/YAP/zebra 10

To clean the benchmarks with a given system use MAKE_CLEAN in the
associated directory (e.g. YAP):

	cd YAP
	MAKE_CLEAN
