The ever increasing scale of modern data center demands more effective optimizations, as even a small percentage of performance improvement can result in a significant reduction in data-center cost and its environmental footprint. However, the diverse ...

Modern CPUs utilize SIMD vector instructions and hardware extensions to accelerate code with data-level parallelism. This allows for high performance gains in select application domains such as image and signal processing. However, general purpose code ...

In prior work we proposed Zeroploit, a transform that duplicates code, specializes one path assuming certain key program operands, called versioning variables, are zero, and leaves the other path unspecialized. Dynamically, depending on the versioning ...

The set of events available for execution in a Parallel Discrete Event Simulation (PDES) are known as the pending event set. In a Time Warp synchronized simulation engine, these pending events are scheduled for execution in an aggressive manner that ...

Large scale OLTP workloads on modern database servers are well understood across the industry. Their runtime performance characterizations serve to drive both server side software features and processor specific design decisions but are not understood ...
