Hi All,
I'm getting desparate running either subroutines in parallel
or commands run on the commandline.
There's Parallel::Jobs, Parallel:ForkManager and another
one.
Point is: I want many jobs run in parallel (for indexing
purposes), example:
my @collections = qw (col1 col2 col3 col4 col5);
my max_tasks = 3;

foreach my $collection_alias (@collections) {
   start_parallel_task($collection_alias);
}

wait_until_all_processes_have_finished();

[download]

Also, all output from the sub-processed should write to
STDOUT & STDERR of the parent.

It seems that the different modules can accomplish about
90% of my wish, but lacks the other 10%.

Can s'one get me a code snippet, which does this exact
thing?
I have read and read and searched and searched and tried and
tried but did not succeed. Please don't shoot if I
read/searched/tried not hard enough. ;-)
On request I can cough-up some snippets that fail.
Thanks in advance, o, enlighted monks.
John
