In a nutshell#
Sherlock features over 1,600 compute nodes, 44,000+ CPU cores and 700+ GPUs, for a total computing power of more than 3.3 Petaflops. That would rank it in the Top500 list of the most powerful supercomputers in the world.
The cluster currently extends across 4 Infiniband fabrics (EDR, FDR, HDR). A 6.1 PB parallel, distributed filesystem, delivering over 200 GB/s of I/O bandwidth, provides scratch storage for more than 5,300 users, and 800 PI groups.
The Sherlock cluster has been initiated in January 2014 with a base of freely available computing resources (about 2,000 CPU cores) and the accompanying networking and storage infrastructure (about 1 PB of shared storage).
Since then, it's been constantly expanding, spawning multiple cluster generations, with numerous contributions from many research groups on campus.
For more information about Sherlock's ongoing evolution and expansion, please see Cluster generations.

For more information about storage options on Sherlock, please refer to the Storage section of the documentation.
Sherlock is architected around shared storage components, meaning that users can find the same files and directories from all of the Sherlock nodes.
- Highly-available NFS filesystem for user and group home directories (with hourly snapshots and off-site replication)
- High-performance Lustre scratch filesystem (6.1 PB parallel, distributed filesystem, delivering over 200 GB/s of I/O bandwidth)
- Direct access to SRCC's Oak long-term research data storage system (26.3 PB)
