Project Crumbler

An proof-of-concept of oppurtunistic computing which also uses cluster computing

This serves as a project as part of the Cloud Computing Course at my university

Architecture

Installation

git clone https://github.com/DarthBenro008/crumbler

Cloud Central Server

To install the central server, use the following:

cd crumbler_central_node
yarn 
yarn start

You will get an message that:

Server started succesfully in port 3000

Using Dockerfile

Run the following commands

cd crumbler_central_node
docker build . -t crumbler_node:latest
docker run -p 3000:3000 crumbler_node:latest

Mobile App

Building

It is recommended that you run Gradle with the --daemon option, as starting up the tool from scratch often takes at least a few seconds. You can kill the java process that it leaves running once you are done running your commands.

Tasks work much like Make targets, so you may concatenate them. Tasks are not re-done if multiple targets in a single command require them. For example, running assemble install will not compile the apk twice even though install depends on assemble.

Clean

gradle clean

Debug

This compiles a debugging apk in build/outputs/apk/ signed with a debug key, ready to be installed for testing purposes.

gradle assembleDebug

You can also install it on your attached device:

gradle installDebug

Release

This compiles an unsigned release (non-debugging) apk in build/outputs/apk/. It's not signed, you must sign it before it can be installed by any users.

gradle assembleRelease

Test

Were you to add automated java tests, you could configure them in your build.gradle file and run them within gradle as well.

gradle test

Results

Why calculation of prime numbers?

We are using Sieve of erasothaneses to calculate prime numbers upto high like 2^25. We are doing this using web-socket and power of cluster computing,

we were able to achieve a whooping 50% efficiency than runnning it an normal node.
