Occasionally researchers need exclusive use of computing resources in order to
perform experiments where timing constraints are critical. Experminents of
this type cannot be performed on systems that are sharing resources like
memory and disk space with other competing processes. In realizing the
importance of such research HPCVL Carleton has implemented tools and
proceedures to allow scientists to have exclusive use over designated
computing resources.
By using schedulers like Maui and Grid Engine for the Beowulf and SunFire
repectively HPCVL system administrators can reserve system resources for the
exclusive use of research groups, individuals, or processes. Through the use
of these tools HPCVL researchers can obtain dedicated access to computing
resources without interfering with other system processes.
HPCVL Carleton's system administrators will be responsible for managing and
maintaining computing resources for research groups. After requests for
resource reservation have been approved by lab directors HPCVL system
administrators will make the resources available to the research group(s) that
require exclusive access. After a predetermined time period or once the
experiments have been completed the system resources will be returned to the
HPCVL user community.
In order for users to ensure accurate and repeatable results for their
experiments it is important that they carefully follow the scheduling
policies. Failure to use scheduling tools can result in faulty system
management and lost data.
