Increased parallelism on a single processor is driving improvements in peak-performance at both the node and system levels. However achievable performance, in particular from production scientific applications, is not always directly proportional to the core count. Performance is often limited by constraints in the memory hierarchy and also by a node interconnectivity. Even on state-of-the-art processors, containing between four and eight cores, many applications cannot take full advantage of the compute-performance of all cores. This trend is expected to increase on future processors as the core count per processor increases. In this work we characterize the use of spare-cores, cores that do not provide any improvements in application performance, on current multi-core processors. By using a pulse-width modulation method, we examine the possible performance profile of using a spare-core and quantify under what situations its use will not impact application performance. We show that, for current AMD and Intel multi-core processors, spare-cores can be used for substantial computational tasks but can impact application performance when using shared caches or when significantly accessing main memory.

A key determinant of overall system performance and power dissipation is the cache hierarchy since access to off-chip memory consumes many more cycles and energy than on-chip accesses. In addition, multi-core processors are expected to place ever higher bandwidth demands on the memory system. All these issues make it important to avoid off-chip memory access by improving the efficiency of the on-chip cache. Future multi-core processors will have many large cache banks connected by a network and shared by many cores. Hence, many important problems must be solved: cache resources must be allocated across many cores, data must be placed in cache banks that are near the accessing core, and the most important data must be identified for retention. Finally, difficulties in scaling existing technologies require adapting to and exploiting new technology constraints. The book attempts a synthesis of recent cache research that has focused on innovations for multi-core processors. It is an excellent starting point for early-stage graduate students, researchers, and practitioners who wish to understand the landscape of recent cache research. The book is suitable as a reference for advanced computer architecture classes as well as for experienced researchers and VLSI engineers.

Single chip multicore processors are now prevalent and processors with hundreds of cores are being proposed and explored by both academia and industry. Shared memory cache coherence is the state-of-the-art technology for these processors to enable synchronization and communication between cores. However, since the synchronization of cores on shared data using hardware cache coherence suffers from instruction retries and cache line ping-pong overheads, it prevents performance scaling as core counts increase on a chip. This thesis proposes to utilize a novel moving computation to data model (MC) to overcome this synchronization bottleneck in a 1000-cores scale shared memory multicore processor. The proposed MC model pins shared data to dedicated cores called service cores. The execution of critical code sections is explicitly requested from worker cores to be performed at the service cores. In this way, the cache line bouncing between cores is prevented, hence data locality optimization is enabled. The proposed MC model utilizes auxiliary in-hardware explicit messaging for the critical section requests to enable efficient fine-grained blocking and non-blocking communication between communicating cores. To show the effectiveness of the proposed model, workloads with wide range of synchronization requirements from graph analytics, machine learning and database domains are implemented. The proposed model is then prototyped and exhaustively evaluated on a 72 core machine, Tilera Tile-Gx72 multicore platform, as it incorporates in-hardware core-to-core messaging as an auxiliary capability to the shared memory cache coherence paradigm. Since the Tile-Gx72 machine includes only 72 cores, it is deployed for evaluation at 8 to 64 core count scale. For further analysis at higher core count, a simulated RISC-V multicore environment is built and utilized, and the performance and dynamic energy scaling advantages of the MC model is evaluated against various baseline synchronization models up to 1024 cores.
