Cluster Pi: Build a Raspberry Pi Beowulf cluster (Udemy.com)

Course covered all of the steps you will need to perform to get your cluster working. The instructor was very easy to understand. I thought his delivery of an advanced topic helped me understand an advanced subject.

Audio was a bit off. Expectations on what you can do could be expanded especially with the Raspberry Pi 4 B 4GB models that are now available. That said, it was still a nice intro into mpi4py.

I like that the instructor kept on target in a nice logical order. I used Raspberry Pi B+'s (4). OS was NOOBS v2_8_2 and I used mpi4py-2.0.0 instead of 1.3.1. Except that I forgot to install SSH, the whole thing went well with Win32DiskImager. When I saw that "helloworld" returned from all the Pi's, I was a happy man. Thank you for giving me the supercomputer I've been wanting.

Ich habe zu diesem Thema bereits einige Videos auf youtube gesehen, die aber leider entweder unter schlechter Aufnahme / zu kleine3r Darstellung / zu schnellem Bildwechsel litten. Was ich vermisse, sind etwas detailliertere Erklärungen für Benutzer, die keine tieferen Erfahrungen mit Raspbian / Linus haben ( Ich hätte das Ganze gerne unter Windows gemacht, aber die von Microsoft hierfür bereitgestellte Software ist viel zu umfangreich für den limitierten Speicher des Raspberry. Daher habe ich mich für Raspbian entschieden, bin aber jetzt kein erfahrener Linux User. Ich habe vor ca. 35 Jahren erste Erfahrungen mit Unix V gemacht uns das System seither gemieden wo ich konnte).

This "course" feels like and gives barely as much info as blog walk-through. I'm disappointed that I even paid the discounted amount.

Straightforward, step by step instructions which helped me avoid at least one pitfall I'd have fallen into. Now to put it in action.

I am learning and building a small supercomputer!! I am also taking data science courses on Udemy...

As someone who still has a lot to learn about the Raspberry Pi and about clusters in general, I found the instructor's explanations clear and thorough. The material was presented in a straightforward manner, and I was able to follow along surprisingly easily. I look forward to more courses from this instructor!

Setting up a cluster can be a painful, awful experience, especially if you're flying by the seat of your pants. Wolf gives an incredibly easy-to-follow course that is chock full of information (and stuff I would have definitely had to learn the hard way, like "It would make the most sense to do action Y here, but if we do this bad things will happen because of X and Z and we'll have to reinstall the operating system." Yikes!) Overall I was able to complete the course in just under eight hours with five nodes from start to finish. I began with a pile of parts and ended with a cohesive system that I could already run tests on and prove that it worked. The information is easy to follow along with and the slides lay out each command with various pitfalls you may run into along the way; I didn't have a single unexpected surprise. I definitely recommend this as a great way to get launched head-first into everything, even if you've done it before! My background is designing, building, and running a 115 node cluster for my alma mater, but things have changed a bit since I had that pleasure. Now I have my own again to code for, and I look forward to learning more about making it tick!

The instructor does an excellent job of explaining how to build your own Cluster Pi. Like his other courses, he is well organized, clear and presents technical matter such that anyone can understand it. An excellent educational tool, highly recommended.
