On the Extreme Science and Engineering Discovery Environment (XSEDE), Gordon ( is an Appro International digital compute service hosted by San Diego Supercomputer Center (SDSC).

Built specifically to support data-intensive computing, Gordon features:

  • 1,024 compute nodes, each equipped with two 8-core 2.6 GHz Intel Xeon Sandy Bridge processors and 64 GB of DDR3-1333 memory
  • 64 I/O nodes, each equipped with two 6-core 2.67 GHz Intel Xeon Westmere processors, 48 GB of DDR3-1333 memory, and 16 Intel 710 Series 300 GB flash-based solid-state storage devices (SSDs), providing 4.4 TB of usable fast flash memory per node

Most "native" compute nodes on Gordon are equipped with a single 300 GB flash-based SSD, providing 280 GB of usable fast flash memory per node. For compute jobs that need more flash storage, Gordon also provides four "bigflash" nodes and 32 vSMP nodes:

  • Bigflash nodes: These "native" compute nodes each have access to a separate 4.4 TB flash-based SSD; for more, see ARCHIVED: On Gordon (SDSC), what are the "bigflash" compute nodes?
  • vSMP nodes: Using a virtualization solution designed by ScaleMP, each vSMP "supernode" aggregates 32 compute nodes and two I/O nodes, providing access to two 4.4 TB RAID 0 devices, each built from 16 300 GB flash-based SSDs.

The Data Oasis (SDSC) is mounted on Gordon, providing users access to Lustre-based shared scratch space and allocated project space.
