February 26, 2021 - HW2 and HW3 Overviews

Hello again everyone,

A couple of things:

First, here is the mid-term survey link for you to fill out. I am specifically looking for ideas to make the class better and easier for you:

Link to CMSE401 Survey

Second, when I was editing the videos for today I realized I made a terminology mistake. I was saying the word “Serial” but was thinking the word “Static”. I hope I didn’t confuse too many of you. I added a note in the video where I made the mistake. Let me know if you have any questions.

Finally, here are the videos from today.

Please let me know if you have any questions. See you in class on Monday.

February 19, 2021 - Supercomputer virtual tour

Hello CMSE401 students,

FYI, I just posted last week’s assignments

Last time I taught this course I managed to arrange a tour of the MSU HPCC facility. Unfortunately an in-person tour is not possible. However, on Monday I heard a great talk by Dr. Bronson Messer (Computational Astrophysicist) Director of Science at Oak Ridge National Laboratory (one of the nations biggest HPC facilities). If you are interested, I encourage all of you to watch his talk and check out the on-line virtual tour of Oak Ridge.

February 13, 2021 - Next week’s assignments are posted.

Hello Again CMSE401 Students,

I just finished updating the course website and the student git repository with new assignments for next week. These changes include the new quiz and homework schedule (basically I swapped them out. Please have a look and make sure I didn’t miss anything.

Take care and see you on Monday,

Dirk

February 12th, 2021 - Assignment Schedule Changes are coming

Hello CMSE401 Students,

As I am preparing to post next weeks assignments, I realized that we are not far enough along for you to finish the OpenMP homework (HW2) which I had scheduled to be due next Thursday (February 18). Although all of you should have no problem doing the serial benchmarking, I don’t feel we have had enough practice with OMP for loops and SLURM scheduling.

Unfortunately, I don’t feel like we can easily skip a week which will throw off my schedule completely. Therefore, I am going to rearrange the schedule a bit as follows:

First, Nothing will be due next Thursday February 18th. The Homework will now be due February 25th instead.
Second, I plan on moving Quiz2 from February 26 to next Friday February 19. Quizzes are worth much less of your final grade and I can target the quiz on what we have covered.
Finally, I will then probably just swap the quiz due dates with the homeworks for the rest of the semester (assuming the topics line up okay).

These changes will actually take quite a bit of schedule fiddling on my end. I will not be able to get them done tonight and it may take me much of the weekend (I also need to grade your project proposals). I will let everyone know when I am finished. Please be patient and let me know as soon as possible if you have an concerns regarding this plan.

One final note, I don’t plan to change the pre-class assignments for next week. Therefore I will get them posted tonight so you can work on them as well.

Take care,

Dirk
