IDL's thread pool (search the IDL online help for thread pool for more
information) will do things like that automatically if you just have a
system with multiple processors.

If you want to do more complex tasks than just vector operations then
check out FastDL (it has an MPI interface and a task farming interface,
depending on the level of control you need):
