Project 1 - Bitcoin Mining

Name 						UFID
Sarojini Garapati 			
Sharath chandra Darsha 		4519-4064

Instructions to run the code:

1) Go to the directory containing project1.scala and build.sbt
2) Run "sbt"
3) Run "run 4" // here 4 is the number of zeros in the bitcoin generated
4) Go to the remote laptop directory containing project1.scala
5) Run "sbt"
6) Run "run 192.168.2.3" // here instead of target zeros, enter the ip address of master

How to calculate cpu usage:

1) Run "time sbt run 4"
- At the end of the program, it dispays real, user and sys time. cpu usage is (user+sys)/real

Results:

1) Optimal worksize = 1000000

2) result of project1.scala 4

3) the system has 4 cores
   cpu time = 138.059
   real time = 40.973

   cpu usage = 138.059/40.973 = 3.369

4) The coin with the most zeros is with 6 zeros and ran for two minutes

No of workers spawned is 4
