Parallel Processing, Processes, and Threads

If you've been wondering what multi-process programming is all about, here's a link to a good online tutorial. This shows the concepts of parallel programming using processes and threads. The articles themselves have nothing to do with Perl, but all the concepts apply. The examples are very simple, and I feel that if you can read Perl, you should be able to read the 'C' examples.

It is my personal conviction that people using these facilities under Perl are served well by having a good understanding of the actual underlying libraries they are built on. This becomes particularly true when chasing race conditions, and the odd data corruption bugs.

I've seen one or two decent tutorials for Perl in the ORA books, but these tutorials are better written, and contain more detailed explanation of what happens, and why.

Be aware, Perl does not currently do multi-threading well, but it's perfectly capable of multi-processes.

Also, if you are interested in threads, particularly the Pthreads (a concatentation of POSIX Threads) libraries, the ORA Pthreads Programming book is very good. And for POSIX functionality in general, ORAs POSIX: Real World Programming is a must have.

Here's the books in question, for those of you playing at home: Pthreads Programming POSIX 4: Programming for The Real World Programming with POSIX Threads UNIX Network Programming: Networking APIs: Sockets and XTI: Volume 1	[reply]

I also humbly suggest the excellent "Programming with POSIX Threads" (Addison -Wesley/Author: Butenhof) as well as the excellent series from the late W. Richard Stevens, particularly "UNIX Network Programming: Volume One" which covers pthreads and sockets (threaded servers).

I have also written a very small tutorial (GRID::Machine::perlparintro) that through a simple example introduces how to have "Parallel Compting" in Perl Hope it Helps Casiano	[reply]
