First CS Graduate Research Symposium at the University of Iowa

High Performance Stream Processing for Mobile Sensing Applications

Invited talk, Nov. 6th, 2015.

A mobile sensing application involves sensor reading and data stream processing, both of which require real-time performance and efficient resource usage. To address the challenges, many compile-time optimizations through program analysis are proposed to improve the runtime efficiency. In this talk, I am going to introduce our recent contributions in this field including CSense and ESMS. CSense is a stream processing toolkit that facilitates concurrency safety and MATLAB component integration with enhanced memory performance on Android. ESMS stands for Efficient Static Memory management for Streaming that characterizes the whole program memory behaviors through complier-time analysis and exploits data sharing opportunities while eliminating unnecessary memory operations for speedup. Experimental results show up to 8.7X performance improvement and at most 96% reduction on memory requirements.
