The Tera architecture was designed with several ma jor goals in mind. First, it needed to be suitable for very high speed implementations, i. e., admit a short clock period and be scalable to many processors. This goal will be achieved; a maximum configuration of the first implementation of the architecture will have 256 processors, 512 memory units, 256 I/O cache units, 256 I/O processors, and 4096 interconnection network nodes and a clock period less than 3 nanoseconds. The ab- stract architecture is scalable essentially without limit (although a particular implementation is not, of course). The only requirement is that the number of instruction streams increase more rapidly than the number of phys- ical processors. Although this means that speedup is sublinear in the number of instruction streams, it can still increase linearly with the number of physical pro cessors. The price/performance ratio of the system is unmatched, and puts Tera's high performance within economic reach. Second, it was important that the architecture be ap- plicable to a wide spectrum of problems. Programs that do not vectoriae well, perhaps because of a pre- ponderance of scalar operations or too-frequent condi- tional branches, will execute efficiently as long as there is sufficient parallelism to keep the processors busy. Vir- tually any parallelism available in the total computa- tional workload can be turned into speed, from oper- ation level parallelism within program basic blocks to multiuser time- and space-sharing.
