Abstract:

In this talk I will give an overview of my research on statistical approaches to retargetable and adaptive complier optimisation for network applications. I'll start by presenting the motivations for having domain directed complier optimisations by means of workload characterisation techniques.

In the particular case of network applications this showed that transformations targeting data organisation were needed to improve performance. Hence I will present three specialised data transformations we evaluated (structure splitting, array regrouping, and software caching) using real world internet traffic data. These optimisations gave us speedups of up to 2.62, but at the same time showed that no single solution performs equally well across all network traffic scenarios and clearly indicated that adaptive data transformation schemes are necessary to ensure optimal performance under varying network loads. I will conclude by giving an overview of the adaptive transformations we are considering in our current work.

 

Bio: Damon Fenacci is a PhD candidate at ICSA in his final year. His research focuses on statistical approaches to retargetable and adaptive complier optimisation for network applications. Prior to joining ICSA he worked as a complier developer for 5 years.
