**Bio**\

I am a Professor in CDS and 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.\

**Research**\

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 provide solutions
for efficient executions, good speedups, and in general remarkable
reduction in turnaround times of large time-consuming Industrial
applications.\
