We present the design, implementation, and evaluation of single assignment data structures and of a software controlled cache in an existing multi-threaded architecture platform-the Efficient Architecture for Running Threads (EARTH). The software-controlled cache (ISSC) exploits temporal and spatial locality of EARTH split-phased memory transactions for single-assignment memory references. Our experimental evaluation indicates that the caching mechanism for single-assignment storage makes the EARTH memory system more robust to variations in the latency of memory operations. As a consequence the system can be ported to a wider range of machine platforms and deliver speedup for both regular and irregular application
