 Associated Lab: Middleware and Runtime Systems (MARS) Lab

I am an Associate Professor in DCDS (erstwhile SERC), IISc. Prior to joining IISc, from 1999-2003, I was in Innovative Computing Lab of Dr. Jack Dongarra, Computer Science Department, University of Tennessee, USA, first as a PhD student and then as a senior research associate.

My research interests are in high performance computing (HPC) in general, and building middleware and runtime systems for parallel applications and systems, in particular. Our lab, MARS, deals with the following primary areas:

  • HPC Runtime Systems / Application Frameworks: Our lab works on building runtime systems for HPC applications on both accelerator and general HPC systems. We primarily focus on irregular applications including graph applications, N-Body simulations, Molecular Dynamics (MD), and Adaptive Mesh Refinement (AMR) applications. We have also worked with applications in climate science and visualization in collaboration with researchers working in these areas.
    • Accelerator systems: Techniques for load balancing, hybrid executions utilizing both CPU and GPU cores, and efficient executions of different programming models on these systems.
    • Large-scale systems: Scalability studies, tools and techniques, processor allocation, mapping and remapping strategies on HPC network topologies.
  • Middleware:
    • Job Scheduling: Our work is on analyzing job submissions, developing prediction strategies and scheduling techniques that use predictions for efficient job management and utilization of production supercomputer systems.
    • Fault Tolerance: For exascale applications using checkpointing and process replication.

Besides these, we are also eager to learn about and providing solutions for efficient executions, good speedups, and in general remarkable reduction in turnaround times of large time-consuming Industrial applications.
