Quest Technical Specifications

This page contains technical information about the Quest cluster. For an overview of the system, see Quest Overview.

Quest Architecture

Quest has a IBM GPFS parallel filesystem with ESS storage totaling approximately 3.5 petabytes. Users have access to a small (80GB) home directory, as well as a project directory with storage optimized for I/O operations.

Quest comprises four login nodes that users connect to directly and 679 compute nodes with a total of 16,028 cores used for scheduled jobs. Both the login and compute nodes are running the Red Hat Enterprise Linux 6 operating system. Quest’s compute nodes are divided into three partitions:

Job Limits

Researchers using Quest may submit up to 5,000 jobs at one time. General access jobs with a wall time of four hours or less can be run on most of Quest’s compute nodes and will experience the shortest wait times. Longer general access jobs are restricted to approximately 20 percent of Quest’s compute nodes and will experience longer wait times.
