Parallel File Systems
This page contains information on both the Lustre and GPFS file systems. Most LC machines use Lustre, an open source parallel file system. However, the Coral machines came with GPFS instead of Lustre, so now we have both file systems in house. GPFS is IBM's parallel file system (currently known as Spectrum Scale).
To understand Lustre quotas and GPFS quotas (aka "Tiers"), please refer to the March 2019 User Presentation on this topic.
In all cases, the GPFS filesystems exist only on their individual clusters.
NOTE Large systems such as Quartz, Jade, RZTopaz, and Zin have significantly more bandwidth to Lustre.
