Hi,
Just a few quick observations...
When sending a job with many tasks to Xgrid I had one major problem, if I had more
than about ~240 tasks it would do nothing.
I started experimenting a little and found that it didn't matter wether these tasks were
spread out over many parameters(ie: 5 range parameters with 3 inputs each) or just
one (ie: one range parameter with 250 inputs). However, through all these trials the
one constant was that my first parameter was a file.
ie:
command: /usr/bin/perl
Argument 1: File: myScript
Argument 2: Range: From: 1 To: 250 By: 1
-- Doesn't do anything
Then I removed the first parameter, the file, to see what would happen.
ie:
command: /usr/bin/cal
Argument 1: Range: From: 1 To: 10000 By: 1
-- This works
So, the problem seems to be the fact that I use a file as a parameter, for whatever
reason this bottlenecks the number of tasks to about 240. Perhaps Xgrid has trouble
calculating the size of the job when there is a file involved? Has anyone else had this
problem? Or, better yet, found a way around it?
Thanks in advance.

P.S: Is there a way to call a perl script without using the perl command. For example, is
there an extension I can give my perl scripts that will let them be run just by entering
the script name in the command prompt, is there an environment variable to do this, or
perhaps another solution?
