I am a Ph.D. student in
College of Computer and Information Science at
Northeastern University. I am working with
Gene Cooperman in the High Performance Computing Lab.
Before coming to Northeastern, I did my Bachelor of Science from Jai Narain Vyas University, Jodhpur, INDIA.

Current Research / Projects:
-
Distributed Multi-Threaded Checkpointing (DMTCP)
- DMTCP is a tool for transparently checkpointing the state of a distributed program spread across many machines without modifying the user's program or the operating system kernel.
- The checkpoint image can later be used to restore program in case of node/process failure or can be migrated to another homogeneous system.
- FReD
- FReD (Fast Reversible Debugger) is a new system that uses temporal search automatically over the process lifetime to rapidly travel back in time to an earlier point of interest.
- Two important components of FReD are deterministic replay and checkpointing. Deterministic replay is a prerequisite for such a system. Checkpoints are used to speed up the search.
- FReD can reversibly debug multithreaded applications.
- FReD also supports reverse expression watchpoints, a form of temporal search within a process lifetime. For example, the current value of a user specified expression indicates a bug. The user asks URDB/gdb to go back in time to a statement where the expression is about to take on its current value. This uses binary search: if n statements have been executed, URDB finds the point in time using only log2 n evaluations of the expression.
-
URDB: Universal Reversible Debugger
- URDB is a universal reversible debugger that adds reversibility to almost any debugger through a python-based wrapper. URDB supports multi-threaded and multi-process applications, as well as distributed computations. URDB gains its reversibility through the use of DMTCP.
- It currently has four personality modules, which support: gdb; MATLAB; python (pdb); and perl (perl -d).
