What does a General Purpose Throughput Computing solution look like • Start with a Powerful, yet efficient, Uniprocessor • Perhaps a next generation Opteron would be a good choice ☺ • Deploy one or more of these for excellent general purpose legacy support, and as for the Centralized Controller for throughput • Add a larger number of small, power-efficient, domain optimized compute offload engines • Build an optimized memory system • Shared among all the processors • Optimized support for communication, synchronization & data transfers • Embrace a programming model abstraction that favors simplicity and programmer productivity Accelerated Computing with Heterogeneous Processors! 14 7/17/2008 The Role of Accelerated Computing in the Multi-core Era
Accelerated Computing: Motivations New and emerging applications are defining and operating on larger-scale and more abstract data types Targeted special purpose HW solutions can offer substantially better power efficiency and throughput than traditional microprocessors when operating on some of these new data types. Traditional “host” offload to dense compute accelerator • Use APIs to enable this without heroic programming efforts • Use Concurrent Runtime to ease scheduling & resource management • ISA compatibility yields to API and Platform Compatibility Accelerated Computing is a Platform for Heterogeneous Computing 15 7/17/2008 The Role of Accelerated Computing in the Multi-core Era
