Raghunath Raja Chandrasekar


I am a sixth year PhD candidate at the Department of Computer Science and Engineering at The Ohio State University, U.S.A. I'm a Graduate Research Associate with Dr. Dhabaleswar K. Panda at the Network-Based Computing laboratory. I also closely collaborate with Adam Moody and Kathryn Mohror from the Computation Directorate of Lawrence Livermore National Laboratory.

My PhD research is primarily focused on two main aspects of High-End Computing - resilience and I/O. I am exploring better ways to exploit the hierarchical storage infrastructure available to current-generation supercomputers. I also work on the system-level fault-tolerance features, such as Checkpoint-Restart and Process Migration, of the MVAPICH MPI library that is used by over 2,000 organizations in 70 countries. I am also interested in --- designing highly-scalable runtime systems; efficient I/O and parallel file systems; resilience and fault-tolerance for High-Performance Computing (HPC) architectures; modern Non-Volatile Memory (NVM) architectures; energy-efficiency; profiling tools; parallel application performance optimization and tuning;

Head over to the "Research" page for more information on my research-work, or take a look at my Curriculum Vitae [] for a detailed breakdown of my research and experience. Bonus: You can find an illustration of my rich academic lineage here.

In what now seems like my past life, I was awarded a Bachelor's degree with a major in Information Technology from Anna University, India. During my undergraduate study, I worked with Dr. Sumathi Ganesan, then Head of the Department of Information Technology, to develop a runtime framework that provides an interface between Grid-computing and mobile-computing platforms.



Somewhere, something incredible is waiting to be known.
