I am a Distributed Systems Engineer at
which I joined in
August 2014. Before that, I completed my PhD at
College of Computer and Information Science
at Northeastern University
I was 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.

User-Space Process Virtualization in the Context of Checkpoint-Restart and Virtual Machines
Operating Systems, High Performance Computing and related areas.
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.
- Fast Reversible Debugger (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
FReD/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, FReD finds the point in time using
only log2 n evaluations of the expression.
