I tried to run several tasks (written in perl) on a 8-core node (divided into 8 tasks), but encounter an error for finding a perl module. I tested single task on one thread, no such problem occurred. The weird thing is that the module path is already in ENV path when checking with perl -V. The perl file that gives error begins like this:

#!/usr/bin/perl
use strict; 
use warnings; 
use XML::Parser; ...
[download]

Error message is like this:

Can't locate XML/Parser.pm in @INC (@INC contains: ...  /usr/lib64/per
+l5 /usr/share/perl5 .) at ./blast_parser.pl line 4.
BEGIN failed--compilation aborted at ./blast_parser.pl line 4.
[blastall] FATAL ERROR: File write error
[download]

The interesting thing is that XML::Parser.pm is in the path of /usr/lib64/perl5 that is listed in above @INC and in %ENV (I checked). I tried to include this path in perl file (use lib ), but got same error message. Couldn't figure out where is wrong and how to solve. The perl version: v5.10.1 (*) built for x86_64-linux-thread-multi. Linux version: 2.6.32-358.2.1.el6.x86_64 Thanks for any suggestions. Wayne

  <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).
