Assignment 2 due date extended

Dear Students,

The due date for assignment 2 is now extended till 15th September.

Assignment 3 Submission Guidelines

Dear Students,
 
We hope that you have been implementing the code for assignment 3 on your local machines / virtual box. We would like to clarify how the evaluation for this assignment will be done.
 
You have to finally submit the MatMul.c file. We will be compiling this with our version of main.c which will be similar to what is provided as reference in the assignment. This code validates that the multiplication result is correct and measures the performance of the kernel MatMul for different parameters (varying the size of the matrices, block size, number of threads, etc.). Your final evaluation will be done on the basis of the performance achieved for different test cases (provided that the output is correct). The final date for submission is 22nd September.
 
In order give you insights into the performance your code is getting on the test system where we will be evaluating, we are enabling a feedback mechanism for you. You can submit the file MatMul.c every day. We will be downloading all the submitted files at 9 P.M. everyday (starting 13 September). We will run the code for different test cases and send you a mail with the performance results the next day. None of the results of the intermediate submissions will be used in the evaluation. Make sure that the last submission you make before 22nd September is the correct one. After 22nd September, we will be making runs with the last submitted files and using that for the final evaluation.
 
Please note that we will be killing jobs running for more than 5-6 minutes. The test cases are expected to run well within this time.
 
Regards.
 

Week 4 Lecture Videos

Week 4 Lecture Videos have been released on the course webpage.

Assignment 3 Submission Guideline

Hi everyone

Hope the course is going well for all of you.
For submitting Assignment 3, there is a link to upload you submission via google drive. You must upload your "MatMul.c" file as the submission for the assignment which will be tested against our main.c file. The file name you upload should be exactly "MatMul.c" otherwise your submission will not be graded.

We will download the submission once a day at 9pm (you will be informed if this changes) and run your submission on a standard machine. The results will be mailed back to you on the next day. Your last submission before 9pm each day will be the one that is evaluated.

Your submission on the last day of the assignment will count as your final submission for the assignment.

We will send out another announcement formally mentioning the start of grading, but you can expect this to start tomorrow (we are setting everything up in the meantime).

Assignment 3 and Assignment 1 Solutions

Solutions to Assignment 1 and explanations have been released as a lecture under the Unit 6 : Week 1 Assignment.

Assignment 3 for Week 3 has been released. You can start working on it on your personal computers. We will shortly release submission details corresponding to this programming assignment.

Programming with OpenMP

You should start writing  OpenMP code and test it on your system. The recommended way to do this is to install VirtualBox on your system ( https://www.virtualbox.org/ ) and use the Linux Lite image ( http://www.osboxes.org/linux-lite/#linux-lite-36-vbox ) that already has the OpenMP compatible gcc compiler setup. To create the image, carefully follow the instructions at https://www.linuxliteos.com/forums/tutorials/how-to-install-test-and-use-linux-lite-in-oracle-virtualbox/ step by step.
 
Alternatively, you can install gcc or any other OpenMP supporting compiler on your system. We will be using  gcc for checking assignments and therefore should be gcc compatible.
