Item Description: Provides a simplified way to run multiple parallel forks within a program.
Review Synopsis:
Description
Parallel::ForkManager automates the sometimes tedious process of running
multiple parallel forks from a script. It also allows you to control how
many forks run at once, and keeps that many running, which simplifies a
rather complex task. It is extremely simple in operation and well
documented.
Who should use it?
Anyone who wants to implement forking in a script. I wrote a fair bit of forking
code before discovering this module, and I must say, I don't think I'll go back.
It makes life much easier, and isn't that what good perl modules are supposed to
do?
Who should NOT use it?
There are some forking scenarios which are probably too complex for it, although
I haven't found any of those myself yet. It might be difficult to use for
socket server applications, since controlling the timing of the forks could be
tricky. Or fun, depending on your perspective.
Documentation
Excellent - clear examples and concise wording. Even I understood it.
Personal Notes
I've converted almost all of my old fork code to run with this module. It took
just minutes, and performance improved (I was spawning forks N at a time, waiting for them all to die, and then spawning N more. This thing keeps N forks running all the time without Ne+02 lines of code ;-). Highly recommended!!
