Title: Towards HPC-ABDS: An Initial Experience Optimizing Hadoop for Scalable High Performance Data Analytics
Abstract: With the increase in both volume and complexity of data nowadays, a runtime environment needs to integrate with community infrastructure which supports interoperable, sustainable and high performance data analytics. One solution is to converge Apache Big Data stack with a High Performance Cyberinfrastructure (HPC-ABDS) into well-defined and implemented common building blocks, providing richness in capabilities and productivity. HPC-ABDS with about 300 packages aims to provide them in a library form, so that they can be reused by higher-level applications and tuned for a specific domain problem, such as Machine Learning. Harp is an open source project from Indiana University, that builds on our earlier work, Twister and Twister4Azure. We implemented Harp as a library that plugs into Hadoop and enables users to run complex data analysis algorithms on both clouds and supercomputers. We run Harp on K-means, Graph Layout, and Multidimensional Scaling algorithms with realistic application datasets over 4096 cores on the IU BigRed II Supercomputer (Cray/Gemini) where we have achieved linear speedup. This demonstrates the portability of HPC-ABDS to HPC and eventually Exascale systems.
