This project is exploring the cluster approach to symmetric multiprocessing, in which bus-based multiprocessors are interconnected using a more scalable network. Using the Tempest parallel programming substrate, the project is building clusters that extend the shared memory model with fast references to recently used locations across a cluster. The key issue is achieving good performance without resorting to extensive custom hardware. The project encompasses design and some implementation of a high-speed Tempest system that can: provide shared memory across a cluster; use cacheable control registers and queues for communication among processors and I/O devices; and provide hardware acceleration of protocols. The project includes the development of programming tools and compilers that facilitate specification and verification of custom protocols, and use these protocols to hide latency.

这个项目正在探索对称多处理的集群方法，其中基于总线的多处理器使用更可扩展的网络互连。 使用Tempest并行编程基础，该项目正在构建集群，扩展共享内存模型，快速引用集群中最近使用的位置。 关键问题是在不诉诸大量定制硬件的情况下实现良好的性能。 该项目包括高速Tempest系统的设计和一些实现，该系统可以：在集群中提供共享内存;使用可缓存控制寄存器和队列进行处理器和I/O设备之间的通信;并提供协议的硬件加速。 该项目包括开发编程工具和编译器，以促进自定义协议的规范和验证，并使用这些协议来隐藏延迟。
