Hello, my name Is Hariharan

I am a I/O Researcher

I am a Computer Science Researcher in the Scalable Computing Software Laboratory at Illinois Tech (Formerly known as Illinois Institute of Technology). My research interests are in scalable scientific data management. More specifically, I am interested in parallel I/O, data management systems for managing scientific data, and heterogeneous computing. I am also interested in convergence of Big Data and HPC storage systems.

Fields of Interest

Research

Scientific I/O research

I have deep understanding of various HPC and Cloud storage systems. I have architect several storage platforms such as LABIOS, Hermes, etc.

Development

HPC tools and software

I have built several HPC software such as Hermes Container Library, Hierarchical Prefetching and Compression Software, Intelligent Compression framework, etc. 

Projects

Current Active Research Projects

Stimulus

a user-space distributed library for enables efficient I/O pipeline for Deep Learning Applications. It enables a decoupled and asynchronous data pipeline paradigm. 

Hermes

a new, heterogeneous-aware, dynamic, and distributed I/O buffering system. Hermes enables, manages, supervises and extends I/O buffering to fully integrate into the DMSH.

LABIOS

a new, distributed, Label- based I/O system utilizing asynchronous I/O, supports heterogeneous storage resources, with elasticity, and in-situ analytics.
