Light-weight job dispatch on multiple machines

[Peng Yu]

Hi, I'd like a command line job dispatch tool to dispatch jobs (each
job is independent from each other and may have different input
parameters) on multiple linux machines.

I am not looking for complex tools like sun grid engine or torque.
Rather, I am looking for something with very little configuration (for
example, the minumal configure is just the machine names and how many
jobs each machine can run in parallel).

Do anybody know if such a light weighted tool available? Thanks.
