Hello Monks
I have an odd problem.
We are running dual core pentium 4's with hyper-threading enabled.
The perl scripts that we have run threads or multiple threads. And run just fine with the hyper-threading enabled.
We ran into a machine with hyper-threading DISABLED, and the scripts did not even get off the ground. We had our first print statement execute, then the threads went into lala land.
The threads are created and join'd as follows:
foreach $host (@syshosts)
{
threads->new(\&locateSysHost_Parallel, $host);
}
(threads->list)[0]->join while threads->list;
When we changed the join to
foreach $host (@syshosts)
{
threads->new(\&locateSysHost_Parallel, $host)->join;
}
the threads ran as we expected.
Has anyone else had these weird issues occur?

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).

or How to display code and escape characters
are good places to start.
