$HOME

Standard home directory
Not allocated
Small, standard quota
Larger requests should be on $PROJECT

$SCRATCH
Parallel High-performance filesystem

DDN storage subsystem with approximately 4PB usable capacity for temporary (/scratch) storage.
Aggregate performance of 35GB/s. Available to all nodes.
Not allocated
Purged - inactive data will be purged

$PROJECT
External persistent storage

Provided by the NDC.
Available to compute nodes, but not designed for parallel I/O workloads.

High performance interconnect

Intel OmniPath (version 1) interconnect (100Gbit/s bandwidth). A low-latency high-performance fabric connecting all nodes and temporary storage.
The design of Cedar is to support multiple simultaneous parallel jobs of up to 1024 cores in a fully non-blocking manner. For larger jobs the interconnect has a 2:1 blocking factor, i.e., even for jobs running on several thousand cores the Cedar system provides a high-performance interconnect.
