How to make parallel processing rather than serial processing ??
Hello everybody,
I have a little problem with one of my program. I made a plugin for collectd (a stats collector for my servers) but I have a problem to make it run in parallel.
My program gathers stats from logs, so it needs to run in background waiting for any new lines added in the log files.
My problem is that I call my program in a bash script that tails my log files, like this :
The problem is that it does not work very well. So I would like to make the "tail -f" parallel processing directly in my perl program.
Here is the perl program (collection.pl) I'd like to make parallel processing with :
I have seen that parallel processing could be done with fork or something like that but I don't really understand how to do it. Does anyone has an idea of how I could do that ?

Hey, I just wanted to know how many algorithms there are that cannot be accelerated by parallel processing. I know one such algorithm is Euclid's Algorithm (for GCF). does anyone know any other algorithms that cannot be accelerated by pp? if so please list the names and a general sentence of what...

voxbo(7) The VoxBo Manual voxbo(7)NAME
voxbo - general information about the VoxBo toolbox
DESCRIPTION
VoxBo is a suite of tools for brain image analysis, especially fMRI analysis and lesion-behavior mapping. VoxBo includes over 100 tools,
including many for general-purpose image munging (e.g., vbim(1)), many that implement specific statistical procedures (e.g., vbtmap(1)),
and some that would likely be just as useful for non-imaging applications (vbbatch(1)).
VoxBo has supported cluster parallel processing since 1998. Although cluster installation is a little tricky, it's worth the effort if
you'd like to speed up your analyses by an order of magnitude or two. As of 2010, VoxBo also supports desktop parallel processing on
multi-core systems. We do not yet support GPU parallel processing.
All VoxBo tools support a common set of file formats. See voxbo-fileformats(7) for more information.
AVAILABILITY
Pre-built VoxBo binaries are available for Linux, OSX, and Cygwin, and via the NeuroDebian project (neuro.debian.net) for Debian deriva-
tives.
