—Graphics processors (GPU) offer the promise of more than an order of magnitude speedup over conventional processors for certain non-graphics computations. Because the GPU is often presented as a C-like abstraction (e.g., Nvidia's CUDA), little is known about the characteristics of the GPU's architecture beyond what the manufacturer has documented.

Die-Stacked DRAM caches offer the promise of improved performance and reduced energy by capturing a larger fraction of an application's working set than on-die SRAM caches. However, given that their latency is only 50% lower than that of main memory, DRAM caches considerably increase latency for misses. They also incur a significant energy overhead for(More)
