This is the last freely redistributable version (newer ones are available under a restrictive license, though still at no charge). Rodney Mach <rmach@engin.umich.edu> helped by finding the distfile. He has written a patch to this version of PBS for AFS support. The patch is available through http://www-personal.engin.umich.edu/~rmach/pbsafs/ . PR: 12188 Submitted by: David A. Bader <dbader@eece.unm.edu>

|
|
The Portable Batch System (PBS) project was started to create a
|
|
flexible, extensible batch processing system for heterogeneous computing
|
|
networks. You can submit your batch job on any machine and PBS will run your
|
|
script on the machine you request when the resources you need are available.
|
|
Your PBS system administrator can define the method used to choose what jobs to
|
|
run where, and in what order. PBS can be installed on almost any UNIX machine,
|
|
from single-processor workstations to workstation clusters and massively
|
|
parallel supercomputers.
|
|
A typical batch queuing system has a set of queues. Within each queue,
|
|
jobs are selected in FIFO order. This limits the scheduling policies available
|
|
to the adminstrator. The purpose of PBS is to provide additional controls over
|
|
initiating or scheduling execution of batch jobs, and to allow routing of jobs
|
|
between different hosts. PBS's independent scheduling module allows the
|
|
administrator to define what types of resources, and how much of each resource,
|
|
can be used by each job. The scheduling module has full knowledge of the
|
|
available queued jobs, running jobs, and system resource usage. Using one of
|
|
several procedural languages, the scheduling policies can easily be modified to
|
|
suit the computing requirements and goals of any site. PBS also has a mechanism
|
|
allowing users to specify unique resources required for a job to complete.
