Lansing in-person for Michigan!/usr/group - Topic HPC and filesystems Part 2

Lansing in-person gathering for Hybrid Michigan User Group event: Last month Sharan Kalwani gave an outsanding talk on high performance computing and filesystems. Unfortunately his talk was cut short due to a power failure caused by storms in the area. Sharan has agreed to come back this month and finish up the talk and provide an opportunity for us to ask him some questions.
If you would like to get caught up on his talk, we have the video of the first part:

Also, we’ve got his slide show here: Slide Show
Here’s a re-print of last months announcement:

This month, Sharan Kalwani will be talking about his own direct experiences in High Performance Computing (used to be called Supercomputing in the days of yore).
We produce and consume an awful lot of data (have to keep them CPUs busy!). So over the decades many techniques and implantations grew – which later became the basis for several commercial/enterprise and also foundational tech for cloud based services.
He would like to share the history of high speed file systems and do a quick review of present day storage.
A seasoned scientific, technical and computing professional, Sharan has
spent over 30+ years’ experience in high performance computing,
engineering applications simulation, benchmarking, networking,
operations, technical support and project management.
He is a senior member of IEEE, ACM, SEMCO, ASEI. He has published a book
on the topic: “UNIX and TCP/IP network security”; and is now working on
his second text, about a new computer programming language. He also
serves as one of the writers/editors of the IEEE Southeastern Michigan
Sections monthly newsletter – Wavelengths. He has also served as Vice-
Chair of IEEE Sustech 2023, IEEE Sustech 2022, IEEE SusTech 2021 Global
Conferences and is on the organizing committee for Online Forum for
Climate Change Technologies 2023, 2024 and 2025.
He is the recipient of:
* 2018 IEEE MGA Achievement award and
* 2024 Engineering Society of Detroit (ESD) Anne O. Fletcher Award
for his various contributions towards technical activities.

Also, we’ll be doing a short presentation on a Unix/Linux topic. This month it’ll be the watch command used for continuously running a command and watching the output
