Techniques for Efficient Processing in runahead execution Engines: Runahead execution is a technique that improves processor performance by pre-executing the running application instead of stalling the processor when a long-latency cache miss occurs. Previous research has shown that this technique significantly improves processor performance. However, the efficiency of runahead execution, which directly affects the dynamic energy consumed by...; Tags: Technique, Performance, Runahead Execution, Productivity, Performance Management, Processors, Human Resources, Workforce Management, Semiconductors, Hardware, Components; White papers
Efficient runahead execution: Power-Efficient Memory Latency Tolerance: Runahead execution improves memory latency tolerance without significantly increasing processor complexity. Unfortunately, a runahead execution processor executes significantly more instructions than a conventional processor, sometimes without providing any performance benefit, which makes it inefficient. This paper identifies the causes of inefficiency in runahead execution and proposes simple -yet effective-techniques to...; Tags: Execution, Runahead Execution, Processors, Semiconductors, Hardware, Components; White papers

Address-Value Delta (AVD) Prediction: Increasing the Effectiveness of runahead execution by Exploiting Regular Memory Allocation Patterns: While runahead execution is effective at parallelizing independent long-latency cache misses, it is unable to parallelize dependent long-latency cache misses. To overcome this limitation, this paper proposes a novel technique, Address-Value Delta (AVD) prediction. An AVD predictor keeps track of the address (pointer) load instructions for which the arithmetic difference...; Tags: Memory, University Of Texas, Allocation, Prediction, AVD, AVD Predictor, Productivity; White papers
An Analysis of the Performance Impact of Wrong-Path Memory References on Out-of-Order and runahead execution Processors: High-performance, out-of-order execution processors spend a significant portion of their execution time on the incorrect program path even though they employ aggressive branch prediction algorithms. Although memory references generated on the wrong path do not change the architectural state of the processor, they affect the arrangement of data in the...; Tags: Performance, Memory, Analysis, Processors, Semiconductors, Hardware, Components; White papers 2005-12-01

Predictive Adaptation for Service Level Agreements on the Grid: Users of Grid systems often need to attach Quality of Service (QoS) information such as time or performance constraints to guarantee timely execution of their application. Grid resources have varying quality and reliability and can easily be swamped by competing applications. If this coincides with the user's execution their results...; Tags: SLA, Execution, Adaptation, Service Level Management, It Operations, It service Management; White papers 2006-01-24
