A COOL-1 multiprocessor shared memory system based on superconductor Rapid Single-Flux Quantum (RSFQ) technology is being developed at SUNY (Stony Brook, USA) within the framework of the Hybrid Technology Multithreaded architecture (HTMT) petaflops project led by JPL. This paper describes a multithreading approach proposed in the COOL-I architecture and mechanisms to exploit the thread level parallelism in RSFQ processors called SPELL-1. Up to 128 fine-grain threads called (instruction) streams arranged in 16 groups of 8 streams each can run in parallel within a SPELL-1 processor. All eight streams comprising each COOL stream cluster can communicate and synchronize directly via shared registers. Fast creation and termination of streams including speculative stream execution are also supported.
