The standard way of doing this is using pipe opens. man perlipc has some examples - the example uses communication between the parent and a single child, but filehandles can easily be saved in a datastructure.
Note that if you use pipe-open, open returns the PID of the child. To determine a child terminating, set up a signal handler to catch SIGCLD. This signal doesn't tell you the pid, but if you do a wait or a waitpid in the handler, you do. Given the PID of the terminated child, you know which task was assigned to it (assuming you stored this information when dealing out the tasks).
Study man perlipc, it's a real treasure trove. It should have enough examples to get you on your way.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
