As more and more users wish to use HPCVL Carleton's computing facilities steps
must be taken to ensure that all users can complete their experiments in an
efficient and timely manner. When there are only a few number of users this
task is trivial but as operations expand coordinating an equitable
distribution of resources among processes becomes difficult.
It is the policy of the lab managers at HPCVL Carleton to guarantee that users
are able to gain access to computing resources in a seamless and efficient
manner given current usage levels. In order to achieve this the lab uses
scheduling software to automate the task or job queuing and resource
management. In order to ensure that all users have fair and equitable access
to computing resources HPCVL administrators must insist that all users adhere
to scheduling policies and use the appropriate scheduling software. All users
are advised to adhere to this policy since failing to do so could compromise
experiment results and cause other users a lot of grief. All processes found
violating scheduling policies will be terminated by system administrators to
ensure an acceptable standard or performance for all users of the system.
All jobs running on HPCVL gear at Carleton must be submitted through the use
of scheduling software running on the host machine. This software is designed
to ensure that all processes are queued and executed in an efficient and
timely manner. Users should familiarize themselves with the proper use of
scheduling software for both the Beowulf and the SunFire since the integrity
of their experiment results depend on it.
The SunFire at HPCVL Carleton University uses Sun's GridEngine as the
scheduling software. GridEngine is a very robust and easy to use software
package allowing users to manage their jobs. Information on using GridEngine
can be found on the HPCVL FAQ (link on this page) or at the Sun Website.
All jobs submitted on the Beowulf use the Maui Scheduler for the proper
queuing and management of jobs. Like GridEngine the Maui scheduler is a full
featured resource management and job scheduling tools that is easy to
use. More information on the proper configuration and use of the Maui
Scheduler can be found on the On-Line Resources section of this page.
