About Ookami

Stony Brook Seawolf logo.Ookami is the first computer outside of Japan with the A64fx processor developed by Riken and Fujitsu for the Japanese path to  exascale computing. Now in early silicon, by focusing on crucial architectural details, the ARM-based,  multi-core, 512-bit SIMD-vector processor with ultrahigh-bandwidth memory promises to retain familiar  and successful programming models while achieving very high performance for a wide range of  applications. It supports a wide range of data types and enables both HPC and big data applications.

The system has 174 compute nodes each with 32GB of high-bandwidth memory and a 512 Gbyte SSD.  This amounts to about 1.5M node hours per year.

  • Thus, 15,000 node hours represent about 1% of the system's annual capacity.
  • Batch jobs are given dedicated access to nodes (i.e., no multi-tenancy).
  • There are currently no quotas enforced on batch or interactive access.  Instead, we currently employ a fair-use scheduler that adjusts your priority based upon your usage.  Thus, you are free to compute as much as you can, unless it starts to interfere with the use by others of the system as a testbed.
  • Quotas may be enforced in the future.
