Using Dijkstra to Route Packages in a Network Overlay

The goal of this project was to use an overlay to communicate between messaging nodes (clients) and the Registry (server) to send messages using threads. It follows the principles of TCP/IP protocols and overlays used in P2P systems. The registry accepts messaging nodes using a server socket and creates receiver and sender threads for that connection. The messaging nodes also have their own sets of threads for the registry and peers. The foreground process in the Registry allows the users to specify commands that creates the undirected graph with all registered nodes, connect to peers to form bidirectional connections, and start sending messages. When all nodes finish messaging each other randomly, the statistics are collected and can be compared to see if any packets were lost during the period.

Fast Multithreaded Matrix Multiplication

This is a very efficient matrix multiplication calculator built using Java and its concurrency libraries. It can be used to multiply matrices populated using a random seed, but it can also be modified to use predefined values. The command line gives you the option to define the size of the matrices, which will be the same for both matrices, the seed used in random to populate the matrices, and the number of threads. The features list below describes the optimizations.

CS455: Introduction to Distributed Systems

Covered fundamental ideas and issues in building distributed systems. Examined issues related to concurrent programming, thread pools and safety, non-blocking I/O, scalable server design, file system design, distributed mutual exclusion and deadlock detection, consensus and consistency, pipelining schemes, distributed graph algorithms, distributed shared memory, distributed objects, and MapReduce.

This is a feature mainly used to demonstrate the use of the handwriting app built using a canvas and CNN. You can use the search bar to search the site for content or to navigate the site by typing in a word such as home, which will take you to the home page. Below the search bar is a canvas where you can draw letters. This is implemented using a digit recognition CNN. As the accuracy is around 89 percent, it might not always produce an accuracte prediction, for example between o and 0. You can use the three button next to the search bar to delete the last character, clear the search bar, and finally search the site.
