Other Projects

Distributed Systems Events Characterization through Cluster Analysis (Fall 2010)

Logs obtained from real distributed systems executions contain useful information in

understanding and uncovering performance problems. However, their complexity leads to

overwhelmingly large set of logs which is hard to analyze manually. By using a particular

data mining technique: Clustering, we analyze the logs from BitTorrent executions through

a neatly crafted infrastructure. We identified a couple of abnormalities which hamper the

performance of a popular implementation using this technique in a fast and automated

manner.

Efficient Session Type Guided Distributed Object Interaction (Fall 2009)

Multi-party session types provide a way of rigorously specifying protocols of interaction

among multiple distributed participants, by capturing the typed interactions and verifying

them on the program. Our work focuses on automatically extracting performance improvements

on session type enhanced programs for optimization techniques such as RPC batching and

chaining. This was done as a course project and submitted to ECOOP 2010.

Performance Evaluation of Google Cluster Architecture using Mace (Fall 2008)

The project aimed at characterizing the Google cluster Architecture (a distributed system

for Web search), for various system configurations to find the perfect configuration for a

target deployment. Mace was used to implement this system and Amazon EC2 for running the

application. This was done as a course project.

Creation of an Automatic Assembly program Generator for Microprocessors (Final B. Tech

project, Spring 2008)

With Prof. N Ramasubramanian. The project was aimed at creating software that would take

the specification of any microprocessor in detail and then generate random assembly level

programs that can be used for verification of the RTL design of the processor.

Performance evaluation of the Protocol for Evolutionary Addressing as a part of Summer

Fellowship Program, Indian Institute of Technology, Madras (Summer 2007)

With Prof. SV Raghavan. Designing and building an emulation model in software that was

used to implement the Protocol for Evolutionary Addressing (PEA) for Ad-hoc wireless

networks. Further, other popular protocols of the same class were implemented on the same

platform and compared with the PEA thus leading to a performance comparison.

Study of the x86 architecture of microprocessors, Indian Institute of Technology, Madras

(Summer 2006)

With Prof. V Kamakoti. Dealt with the architectural features of the x86 microprocessor

such as Memory management (segmentation, paging), Task switching, etc. Hands-on experience

with writing Assembly programs for these operations and executing them directly on a

Pentium processor.
