 User storage is available on a high-performance Lustre-based filesystem having 257 TB of usable

+space. This is used for temporary input files, supporting data files, work files, and output files associated with computational tasks run on the cluster. The filesystem is accessible to all of the processor cores via 56 Gbps (FDR) Infiniband. The default stripe count is set to 1 and the default striping is a single stripe distributed across all available OSTs on Lustre. See [[https://www.nas.nasa.gov/hecc/support/kb/lustre-best-practices_226.html|Lustre Best Practices]] from Nasa.
 <note warning>Source code and executables must be stored in and executed from Home (''$HOME'') or Workgroup (''$WORKDIR'') storage.  No executables are permitted to run from the Lustre filesystem.</note>
