Performance Evaluation of the ATOLL Interconnect

The ATOLL System Area Network (SAN) is a low latency interconnect that integrates all required components of a communication system for cluster computing into a single chip. The chip integrates not only four communication devices but also a high performance crossbar. The low latency and the scalability of the ATOLL chip implementation makes it an interesting technology in the area of cluster computing. The following paper presents performance results of basic point-to-point benchmarks together with an evaluation of the use as a cluster interconnect.
