Linking multiple computers together?

[Energize]

Is it possible to link multiple computers on a network together to utilise their processing power for certain applications? I assume that it couldn't be utilised for real time applications though ie games because of latency?

xgrid is available on all Macs

Beowulf Clusters are the classic PC example I think.

Varies on the software, as far as I know most 3d modeling apps can do it, I know for certain 3dsmax can (still yet to try it out though, will be needing it working this semester)
