The Burroughs Scientific Processor (BSP), a high-performance computer system, performed the Department of Energy LLL loops at roughly the speed of the CRAY-1. The BSP combined parallelism and pipelining, performing memory-to-memory operations. Seventeen memory units and two crossbar switch data alignment networks provided conflict-free access to most indexed arrays. Fast linear recurrence algorithms provided good performance on constructs that some machines execute serially. A system manager computer ran the operating system and a vectorizing Fortran compiler. An MOS file memory system served as a high bandwidth secondary memory.
