[Beowulf] "Part-time" beowulf clusters

[Paulo Ferreira de Sousa]

Hello all,

I would like to know information about "part-time" clusters (I don't
know if there's a specific name for it).

The concept I'm thinking, and that I'm sure is implemented already
somewhere, is to use PC's that only are used during daytime, to run
code during night time. A good example is to use the PC's from a
computer lab at any school, connect them to a switch, and use them as
a cluster when they're idle.

Thank you very much in advance.

Paulo
