HPC Workflow I/O Optimization

Working on a collaboration project with LLNL for pinpointing HPC I/O issues and optimizing HPC workflow management based on the findings, e.g., DL Training I/O, Checkpoint/Restart, Producer-Consumer, etc. - summary

BeeGFS Performance Evaluation

Served a collaboration project with LLNL for evaluating the performance of BeeGFS parallel cluster file system using different I/O and metadata performance benchmarks, and Deep Learning applications. - paper

Scalable Data Pipeline for Distributed Deep Learning

Worked on a project at NERSC for profiling I/O in the distributed deep learning applications to explore the I/O bottlenecks, and design and implement optimization strategies to overcome the possible bottlenecks. - abstract, source

Burst Buffer File System

Performed literature survey on enhancing a burst-buffer file system (i.e.UnifyCR) by adding an improved Garbage Collection module. Analyzed the flushing and compaction handling in LevelDB and RocksDB for using those as key-value stores for metadata management in UnifyCR.

Specialized File System for Large Datasets of Deep Neural Network

Assisted a collaboration project with LLNL for designing a file system for large datasets of Deep Neural Network by studying the data shuffling mechanism in TensorFlow and Caffe.

AuthSDK for ringID

Developed the SDK sub-module using C/C++ responsible for authentication functionalities in ringID, a Bangladeshi social networking platform. Worked on making the SDK codebase extensible using various design patterns and integrated Googletest.

Viz Libero

Worked as an active developer in the team managed by Agile methodology for feature implementation and bug fix of Viz Libero, a C++ Qt framework based sports stream augmentation-aiding software. Later, served as a member of the Core development team for performing pre-development research.

Development Automation Test Server

Implemented Model View View Model (MVVM) in Viz Libero and Viz Arena to develop a tool for automatic testing. The tool was deployed as a web service in Vizrt Switzerland's test server and integrated in the development process via Jenkins and Mercurial.

Visual Host

Worked as a member in the Visual Host development team. Visual Host is the MFC based cross-platform(i.e. MainWin was used to generate linux build) framework of the computer-aided engineering tool named Visual Environment. It wraps windows API and MFC classes, develops owner draw customized control menu and toolbar and provides a 3D drawing and animation framework using OpenGL.

Graph Clustering for Parallelizing Graph Algorithms

Implementing a project on the usage of graph clustering for enabling parallelism in graph algorithms on the graph representation of geographical data. The aim is to utilize HPC resources for making graph algorithms more time efficient while maintaining optimal accuracy.

F2PUnifyCR

Developed a Flash-friendly Persistent Burst-Buffer File System implemented on top of UnifyCR. Added F2FS in the UnifyCR for improved SSD garbage collection and implemented asynchronous flushing for adding persistence in UnifyCR. Performed experiments to state the problem and prove the efficacy of the solution. - slides, report

CSE Office Management

An integrated system for automating all the official tasks, i.e., Inventory management, Notice board, Teachers' profile, Peer-to-peer communication, etc., of BUET CSE. Won championship in the intra-department project competition.

Design of a Surveillance System for Dhaka City

Designed and simulated an integrated system to monitor and control the traffic system of Dhaka Applied different shortest path algorithms, e.g., variants of Dijstra's algorithm, A* search, etc., on Dhaka city map Proposed locations for police-boxes on the prominent road-crossings of Dhaka using 2-Approximation Vertex Cover Algorithm Proposed heuristic algorithm that can be applied on clustered map of a large area
