In addition to these checkout some of the examples.

In the source tarball and git repository they're under benchmarks/progs/

There are a few examples that work with parallelism, some are designed to
work with the still experimental auto-parallelism.  However others:

 + various versions of icfp2000 (a raytracer)
 + mandelbrot

These were known to work last time I tried them.

Mandelbrot might be the best to look at first, depending on command line
arguments it attempts to run in parallel in various ways (for comparing
them).
