Abstract
The Gemini System Interconnect is a new network for Cray´s supercomputer systems. It provides improved network functionality, latency and issue rate. Latency is reduced with OS bypass for sends and direct user completion notification on receives. Atomic memory operations support the construction of fast synchronization and reduction primitives.
