About the Edition

With the advent of chip-multiprocessors (CMPs), Thread-Level Speculation (TLS) remains a promising technique for exploiting this highly multithreaded hardware to improve the performance of an individual program. However, with such speculatively-parallel execution the cache locality once enjoyed by the original uniprocessor execution is significantly disrupted: for TLS execution on a four-processor CMP, we find that the data-cache miss rates are nearly four-times those of the uniprocessor case, even though TLS execution utilizes four private data caches.We break down the TLS cache locality problem into instruction and data cache, execution stages, and parallel access patterns, and propose methods to improve cache locality in each of these areas. We find that for parallel regions across 13 SPECint applications our simple and low-cost techniques reduce data-cache misses by 38.2%, improve performance by 12.8%, and significantly improve scalability---further enhancing the feasibility of TLS as a way to capitalize on future CMPs.

Thread-level speculation is a technique that enables parallel execution of sequential applications on a multiprocessor. This paper describes the complete implementation of the support for threadlevel speculation on the Hydra chip multiprocessor (CMP).

Parallelism: • Provides alternative to faster clock for performance • Applies at all levels of system design.B. Each level of cache must be the same size, although blocking can be different. C. The lowest level of memory (e.g L3)is a superset of the next higher level (e.g., L2) D.

L1 and L2 cache must contain the same data E. Everything in L1 cache is also in L2 and L3 Cache F. L1 cache must be consistent with L2 cache at all times.
