Are you running the task_manager program on each machine as where the 
queue daemons are running?

I realize that some of the programs may not be working correctly.  My 
apologies, but progress is rather slow at the moment.  I've just updated 
W. Krebs with the new patches.  Hopefully, they'll be up for people to 
download soon.

These are the necessary steps to run the programs:

1) There needs to be a "my_qdir" subdirectory within the standard queue 
directory.  The queue_manager uses the my_qdir directory to store certain 
files.  All of these files, except for one (the "licenses" file) gets 
created by the queue_manager.

2) The "licenses" file needs to be in the my_qdir subdirectory.  It stores
the total number of licenses that users are allowed to use per license
feature (ie, 10 matlab licenses).  In the updated patches, there is a
default license called "dummylicense" so that users are not required to
specify a license(s) in order to run a job, ie, if they just want to do
something like "queue -- ./a.out".  However, note that the number of
dummylicenses would limit the total number of jobs that users can
run.  Users can change this number if they want.  In the current programs, 
I believe that users do have to specify a license.

3) In order to view what jobs are running and where they are running, 
users simply have to look at the "status" file within the my_qdir 
directory.  Just a simple "cat my_qdir/status" will do.  In the updated
patches, the queue_manager updates this status file quite often.

4) Some of the variables in the queue_define.h file needs to be updated 
before compilation.  QMANAGERHOST -- change the host name of this variable 
to be the name of the server where the queue_manager will be running 
on.  Also, be sure to update the new directory paths of the variables 
QDIR, AVAILHOSTS, ..., TEMPFILE.

5) In order for the task_control program to work correctly, the 
task_manager program must be running on each server where each queue 
daemon is running. 

Please let me know if anything is unclear or if there are any problems.  I
hope this helps!

Monica Lau
