Algorithm and Profiling Profiling a program enable us to see the total amount of time that is spend on all of the functions of a specific execution of an ELF file. Therefore, this means we can view which functions get calls the most and the execution time that is spent. …
Reminder on Stage 1 Previously on stage 1, I have discussed the plan and strategy to attempt to optimize the hashdeep project that I found on GitHub. Hashdeep enables to encrypt a file into unique hash numbers. I’ll try to optimize the SHA256 update function and its time performance on …
Background This is the beginning of the first stage of SPO600 project course. My task is to find an open source software package that includes an intensive CPU function or method which compiles in C, C++ or Assembler. Afterwards, I must perform benchmark tests to get the performance of the …
PART A – Code Comparison and Answers Today’s blog will be separated into two parts. In part A, I will compare my previous sound sample program with a similar program that was provided by our professor. I will then, test the performance and compare it with my solution. You may …
Brief Introduction On this blog, I will test the performance of a sound scale program with different algorithms. I will be performing a simple benchmark test to see the amount of time this takes to run and check if it has improved or not by modifying the source code logic. …
Automatic Vectorization is an interesting topic, mainly because of its performance capabilities. Back then, when computers compilers had to execute large chunks of code in a sequential order (one at a time) it affected the performance speed and time to build the code up. Later, when modern computers were able …
Writing code in assembly language is challenging. Debugging on a larger code is a nightmare to some who never learned assembly before. On this blog, I will write a simple program in assembly for both different system architecture (x86_64 & Aarch64) and will provide a comparison of how they are different …
On this blog, I will investigate the relationship between a basic C source code and the output of the C compiler. I will use windows subsystem for Linux to test the code with GCC compiler. As an example, I will use a simple C program HelloWorld.c and we will see …
The process of getting your code reviewed in an open source environment isn’t easy, and it could take some time for it to get merged, especially if it’s a large project that has large community. On today’s blog, I will go through the process of how codes gets reviewed and …
Hello there! on this blog I will go trough the list of bugs that I have fixed from GitHub. I will share my experience and the process of fixing them. Issue #1 – Firefox Focus for Android For this bug that I have found from GitHub, my task is to make …
