[Beowulf] Good demo applications for small, slow cluster

Yes.. another good choice..
Simple algorithm, lots of ways to divide it up.
Simple enough that the focus would be on the parallelizing, rather than numerical convergence issues or something like that.

Hi Jim,

What about something even simpler, nevertheless challenging:
matrix multiplication?

Slabs or blocks would be a major design choice.

Superlinear scaling could be observed, showing a major performance advantage of parallelization on a cluster.

Best regards,

Max
