File Systems

Anvil provides users with separate home, scratch, and project areas for managing files. These will be accessible via the $HOME, $SCRATCH, $PROJECT and $WORK environment variables. Each file system is available from all Anvil nodes but has different purge policies and ideal use cases (see table below). Users in the same allocation will share read and write access to the data in the $PROJECT space. The project space will be created for each allocation. $PROJECT and $WORK variables refer to the same location and can be used interchangeably.

$SCRATCH is a high-performance, internally resilient GPFS parallel file system with 10 PB of usable capacity, configured to deliver up to 150 GB/s bandwidth.
