Lab 6 continue

With the help of more than two of my classmates, results of lab 6 was produced

After examining the given code, and Professor's hint and suggestion. We were able to measure the time taken to manipulate the samples on each code, by timing the full code then subtract by the timing of the code without the code of manipulating the sample.

(Full code) - (Code without sample manipulating) = (code of manipulation)

The following information are time required for the code of manipulation

Conclusion
First, Xerxes is too powerful for this lab and can't be use to identify which method is faster.

Second, from every other machine test it turns out that the third method "Fix-point" was the fastest method. Which was surprising, during group lab every member conclude the second method "look-up table" would be the fastest.

Course Project Stage 1: deciding which software

Introduction I have finally entering the final stages of SPO600. At this point we (students) are to decide on a software to study upon as the final project of this course. To my understanding, this project consist of three stages: -Fine an open source software (ie. codec) and benchmark its performance on both Aarch64 and x86_64 -Identify the area of poor performance on the software and methods for improvement on both Aarch64 and x86_64 -Dive into the identified area and identify what approaches we have for improvement. Demonstrate on both Aarch64 and x86_64 Deciding on the software After many days of reading..... to be honest I still haven't fully grasp on the detailed procedures of what I have to do. I believe I lack the knowledge to execute all the task required. Since I don't feel confidence in my ability to completing the project, I believe its best to pick a software which I believe I understands. In this case, I decided on one of the file compression software. ...

Course Project Stage 2 Introduction

Issue has arrived!! Since I pushed my work for SPO600 till today because of my other focuses in other school works (my own fault), an issue has arrived. Today unexpectedly all the school remote machine rejected all my attempt for connection. A few days ago, there was an email send from the professor talking about all the machines are going through mass restarts on Friday. We were told to expect Aarchie and Israel might continue to be unavailable even after restart because the restart is done remotely. But today I wasn't able to connection to Bbetty and Xerxes as well which are the only other machines I have access to. Now, I have no choice but resort to one of my last resorts. I'll have to enable the windows subsystem for Linux on my laptop and work from there. Since I don't use my laptop for anything other than school work, this will keep my bench marking and profiling errors to minimum. My laptop system type is 64-bit OS, this would cover at least the Aarch64 part of...
