COSC 407 Assessment
§ In-class/Canvas Quizzes § Lab Assignments
§ Two Midterm Exams
§ Final Exam
10% (using iClicker Cloud/Canvas) 20%
20% – 40% (in-class)
30% – 50% (cumulative)
Clickers: Full mark for correctly answer 80% of all questions.
Midterms are used to improve your mark, not to penalize.
They will help prepare for the final exam. There is 70% of the course grade for all exams.
The exams mark is calculated based on the best of the following options:
§ You must get a combined grade of 50% on all exams and labs to pass the course

§ Lab assignments are critical to learning the material and are designed to prepare you for the exams.
§ The lab component is worth 20% of the total grade (different for grad students).
§ In each lab you will work on assignments with a TA available to provide you with guidance and support.
§ The assignments must be done INDIVIDUALLY (no group work).
§ Focus on programming to help to re-enforce the concepts – Notnecessarilylongprogramsbuttheyrequirethought
about how to implement
Topic 0: Introduction COSC 407: Intro to Parallel Computing
Assignments
§ Assignments are due after one or two weeks from the lab time (dates are indicated in lab assignments)
– Planworkloadahead
§ Except for extreme situations (e.g., illness, childbirth, or bereavement supported by a written proof such as a doctor’s note), late assignments will not be accepted
Topic 0: Introduction COSC 407: Intro to Parallel Computing
Only for COSC 507 students
§ Grad Students enrolled in COSC 507 are required to work on a small project in groups
§ their results live as part of the last lecture on Dec 7th
§ Details will be shared with graduate students regarding projects

How to Pass the Course
The most important things to do to pass this course:
– Attend class/review lectures ahead of time (important!)
– Practice on class materials as soon as possible (critical!)
– Attend labs
– Participate!
– Take notes
– Ask questions (chat, email, interrupt me)
– Do the assignments early as they are designed to help re-
enforce the lecture materials
– Keep up with reading and review
– Plan to spend at least 6 hours/week of out-of-class activities

Academic Integrity
§ Cheating in all its forms is strictly prohibited and will be taken very seriously bytheinstructor. NOGROUPWORKisallowed!
§ Examples of what constitutes cheating: – Assignments
• Working in groups to solve questions and/or comparing answers to questions once they have been solved (except for group assignments).
• Discussing HOW to solve a particular question instead of WHAT the question involves.
§ Academic dishonesty may result in
– an “F” for the assignment or course
– all instances are recorded in the Dean’s office.
– more serious consequences.

Thoughts on Parallel Computing
§ If one ox could not do the job they did not try to grow a bigger ox, but used two oxen. When we need greater computer power, the answer is not to get a bigger computer, but . . .to build systems of computers and operate them in parallel.

Thoughts on Parallel Computing
§ If you were plowing a field, which would you rather use? Two strong oxen or 1024 chickens?
