Sampling is a well-known workload reduction technique that allows one to speed up
architectural simulation while accurately predicting performance. Previous sampling …

Sampling is a well-known technique to speed up architectural simulation of long-running
workloads while maintaining accurate performance predictions. A number of sampling …

Studying program behavior is a central component in architectural designs. In this paper, we
study and exploit one aspect of program behavior, the behavior repetition, to expedite …

Two major trends in high-performance computing, namely, larger numbers of cores and the
growing size of on-chip cache memory, are creating significant challenges for evaluating the …

Computer system designers often evaluate future design alternatives with detailed
simulators that strive for functional fidelity (to execute relevant workloads) and performance …

Architects rely on simulation in their exploration of the design space. However, slow
simulation speed caps their productivity and limits the depth of their exploration. Sampling …

Detailed architectural simulators suffer from a long development cycle and extremely long
evaluation times. This longstanding problem is further exacerbated in the multi-core …
