Techniques for Improving Observed Network Performance

SESSION: Doctoral Showcase - Early Research Showcase

EVENT TYPE: Doctoral Showcase - Early Research Showcases

TIME: 3:30PM - 5:00PM

SESSION CHAIR: Wojtek James Goscinski

Presenter(s):Nikhil Jain


Research on understanding application communication performance on supercomputer networks is important because the scalability of many applications is adversely affected by communication overheads when running on large systems. My preliminary research has been focused on studying various aspects, in the network and in the software, that impacts the observed network behavior. So far, I have worked on following projects: 1)~techniques for correlating performance with factors related to message communication such as link bandwidth, routing scheme etc. (I will present a paper based on it at SC13), 2)~topology aware mapping, 3)~use of simulation and modeling for predicting performance, and 4)~topology aware collective algorithms (papers presented at ICS, Euro-MPI). As I make progress in my doctorate program, the research will focus on end-to-end interaction of networks and applications. This will include classification of impacts of various factors on network performance, fast methods for performance prediction and design/study of future interconnects.
