CS 206 - Spring Semester, 2nd year undergraduate course

Course Book Description

Main reading material: Learning Concurrent Programming in Scala

• Grading Interface
• For more details scroll down to the “Getting Started” section under the heading “Part II: Concurrent Programming”

Parts of this course will run through Coursera, https://www.coursera.org/learn/parprog1/

Students taking this course are requested to provide their Coursera account email by filling up this google form. Note that Coursera requires you to only have one account.

Please note that, when using Coursera, you can choose “I don't want to verify” and “Continue without verification” and you will receive assignment submission tokens that have no time limits, which will simplify the use of the system for this course.

There are three main parts of the course:

• Parallelism (first four weeks): lectures as live lectures and MOOC videos, assignment submission through Coursera
• Concurrency: lectures as live lectures
• Big Data Analysis with Scala and Spark (last three weeks): MOOC

In any case, there will be programming assignments that you will be submitting online.

Continuous control. Components of the grade include:

• written exams during the semester (midterm counting 35%, and the final counting 40% of the grade)
• small programming projects during the semester (all together counting 25% of the grade)

Assignment Due Dates:

• a) Assignment 1: 9th March.
• b) Assignment 2: 19th March (the deadline was relaxed for a few students who had problems with grading infrastructure)
• c) Assignment 3: 23rd March
• d) Assignment 4: 6th April
• e) Assignment 5: 21st April
• f) Assignment 6: 4th May
• g) Assignment 7: 12th May
• h) Assignment 8: 3rd June
• i) Assignment 9: 3rd June
