This folder provides an object for running multi-threading benchmarks. The supported backend Prolog compilers are SWI-Prolog, and YAP.

For example, the following goal will run all benchmark tests:

| ?- mtbatch::run.

You may also run just a single benchmark test a given number of times. For example:

| ?- mtbatch::run(primes, 10).

The following tests are available:

primes			(independent and-parallelism)
msort			(independent and-parallelism)
qsort			(independent and-parallelism)
fib				(independent and-parallelism)
hanoi			(independent and-parallelism)
tak				(independent and-parallelism)
fft				(independent and-parallelism)
integration		(independent and-parallelism)
integration2d	(independent and-parallelism)
search			(competitive or-parallelism)

For the same backend Prolog compiler, the benchmark results can show significant variation depending on the operating-system and if you're using a 32 bits or a 64 bits version.
