Could you recommend job schedulling solution?

I've sinlge 8-way node dedicated for executing long running tasks. To
be able to execute multiple tasks on this node it shoud  spawn each
task in another process. At the same time it should accept network
connection with new tasks without blocking of client and put it on job
queue.

What is "task" ? Executing just ordinary python function will be
enough. If solution contain some client library which allow easy task
submit it will be great.
