  • Asynchronous task creation and scheduling on the SCC processor
    We built a simple runtime for Habanero-C on the Intel Single Chip Cloud Processor.
    We support Async, Flat Finish and Hierarchical Place constructs.

  • Task Graphs in Habanero-C
    We develop a Task Graph generation module for the Habanero-C compiler infrastructure. We modify the Habanero-C compiler to insert function calls before/after every async/finish constructs in an Habanero-C program. The Task Graph is generated with the help of these functions. A single threaded execution of the Habanero-C program generates the Task Graph. The user can also use these function calls to analyze and debug Habanero-C programs.

Past Work
As part of my master's thesis, under the guidance of Prof. Sanjeev Kumar Aggarwal, I designed an efficient lock-free framework for Speculative loop parallelization. The lock-freedom ensures scalability and also minimizes the overhead due to run-time scheduling. The framework handles the speculations with bare minimal memory overhead and handles pointer intensive loops.
Speculative parallelization is a promising technique to expose parallelism in loops with irregular, possibly input-dependent data dependencies that are impossible to resolve statically.
Multicores are now ubiquitous. Many applications are currently sequential and do not utilize the cores efficiently.
