This paper discusses implementations of fine-grain memory access control, which selectively restricts reads and writes to cache-block-sized memory regions. Fine-grain access control forms the basis of efficient cache-coherent shared memory. This paper focuses on low-cost implementations that require little or no additional hardware. These techniques permit efficient implementation of shared memory on a wide range of parallel systems, thereby providing shared-memory codes with a portability previously limited to message passing.
