Title
Performance Evaluation of the Cray X1 Distributed Shared-Memory Architecture
Abstract
The Cray X1 supercomputer's distributed shared memory presents a 64-bit global address space that is directly addressable from every MSP with an interconnect bandwidth per computation rate of 1 byte/flop. Our results show that this high bandwidth and low latency for remote memory accesses translate into improved application performance on important applications.
