Quest-V and DriveOS
-
Quest-V is a partitioning hypervisor.
It runs multiple OS regimes in a multicore machine in isolated cores. I mainly worked on the DriveOS avatar
of Quest-V where it was being used in an electric supercar.

Real-time and Mixed-criticality Scheduling
-
In mixed-criticality systems, real-time tasks have multiple estimates of their
runtime based on the criticality level of the system. Criticality of a system can depend
on different system and envirotnmental factors such as overrun of a critical application,
heavy wind condition for a drone. I work on a dynamic scheduling policy in such mixed-criticality
systems. In addition, I also worked on real-time scheduling of task pipelines or chains
in multiprocessor systems.

Data Transfer Nodes for Cloud-Storage Providers
Under the supervison of Prof. Paul Lu and Prof. Di Niu
-
This project explores the performance of cloud-storages and how their performance differ depending on locations. We are
exploring ways in which we can improve the performance of the cloud-storages. See my thesis (6 MB) for details.

Integrating Traffic Data Stream with Public Route Planning Algorithm and Personalizing it for the End Users
Under the supervison of Prof. Mario A. Nascimento
-
What if route suggestions in Google Maps for public transit considers the current traffic-data! That would surely improve the experience. Our project aims to achieve that. While calculating the route, we also inject traffic delays and modify the route accordingly. Additionally, we also propose to take user's walking speed to be taken from applications like Google Fit, rather than using generic walking speed for all users. Our code is publicly available on GitHub.

Performance Evaluation of Parallel Sorting Algorithms in Shared and Distributed Memory Systems
Under the supervison of Prof. Paul Lu
-
We have implemented two different parallel sorting algorithms and evaluated their performance in distributed and shared memory system. We conclude that choice of the algorithm should be depended on the characteristics of the input keys and the available system. There are other important factors like scalability which should also be considered carefully.

An LLVM Implementation of Shapiro and Horwitz’s PointsTo Analysis
Under the supervison of Prof. J. N. Amaral
-
We have developed a very basic implementation of Shapiro and Horwitz's Alias Analysis in LLVM. Shapiro and Horwitz's Alias Analysis has a good trade-off between the time-complexity and accuracy. That is why we believe, it is a better candidate than Steensgaard's or Anderson's method. Our prototype implementation is available publicly on GitHub.

Development of a Circuit Editor Using Java
Under the supervison of Prof. Manas Hira
-
In spite of the availability of many hardware languages, we don't really have some convenient ways to visualize the circuit-desigining process, make that process easy and share the design in an open and understandable form. In this project, we built a prototype system which could help design a circuit visually and save the circuit in XML format. That XML formatted design could be understood, shared among different design teams.
Circuit Editor is a software which is capable of providing an environment to design different types of circuits with different categories of circuit components. User can create and use their own circuit components as well. This enhances the flexibility of circuit designing. User can save their design and open the design later with the exact graphical orientation.

Development of a REXX tool for z-OS File-Management - Version 1.0 (Module 1)
Under the supervison of Prof. Abhik Mukherjee and Ms. Paroma Sen (IBM)
-
In the Mainframe computers of IBM, data can be stored either in forms of tables (DB2) or files (PS/PDS/GDGs). We have built a file & data management tool which enables the user to create/copy/search/update flat files (PS/PDS). Personally I was involved for the update part of this project. I have implemented 3 types of updates : i) insert string at particular position, ii) replace old string with new one, iii) update particular position with new string in PDS.
