ABSTRACT:
Our team will conduct a set of experiments and demonstrations that achieve novel HPC applications' network performance tuning for over global-scale networks. Our approaches utilize globally distributed high-precision network measurements to detect the traffic characteristics in network exchange points utilizing our novel network measurement systems. Based on the measurement results, we will break overall networks that HPC applications use into several domains. The characteristics of global-scale network are completely different from SCinet local network. Therefore, different techniques for HPC applications' network performance tuning are required. Considering what makes our approach different from other performance tuning projects, the approach breaks end-to-end performance tuning into the different domains tuning with different characteristics, thanks to our novel network measurement systems PRESTA 10G, which is newly developed measurement system consisting of an off-the-shelf PC and a special network interface card. PRESTA 10G offers a 10-Gbps wire-rate packet capturing/generating with multi-layer network-wide analysis and visualization in globally-synchronized timeline. We will visualize the global-dynamic virtualized network and high-precision network measurement results in real-time. Therefore, we can visually demonstrate what the HPC application's traffic is like in different-scale domains among global and SCinet local network. The network path that our HPC applications' packets travel through will be dynamically selected and reconfigured, then network topology will change while the automated path setup.
