This is going to be a short post regarding the result of the test from this post. I forgot to run the test with different optimization levels. So here is it. Running the test again on my laptop: Starting tests STRRCHR2(str2,’/’) returns: /.file STRRCHR2(str2,’.’) returns: .file Test 1: Using original function with multiple instances 12006.000000 […]
In this release, I have been working on this issue (pull request) and also translating Thimble into Vietnamese. The issue was a quite simple fix like last time but it has taken a lot of my time to find where the actual problem is and figuring out how to fix it. Working on the issue The […]
Continuing from the last post, my theory is the strrchr function is currently calling the strchr function multiple times to do its job and I believe that it should perform the task right in the function itself which will be faster. What I have done was looking at the strchr implementation in the string/strchr.c file […]
After looking through a lot of functions in the glibc documentation and looking at their source code to determine if there is a possible way to optimize it, I finally found a function that I can optimize. It is the strrchr function with the following signature: char * strrchr (const char *s, int c) The function returns […]
The project in the course SPO600 is to pick a function in the glibc code as a candidate for optimization. This post is going to be the first phase of this project as I’ve picked my function for the project. The function I have picked is the pow function which receives 2 double variables and returns […]
For this release, I have worked on this bug and this is the pull request to fix the issue. The fix seems simple and the issue looks simple as well, but the issue is much more complicated than it looks and the fix isn’t quite simple to get there. The Issue The source of this issue […]
For this week lab, we are continuing to used the code from the previous lab to create a web service and deploy it on the cloud using Heroku. There are many PaaS (Platform as a Service) that we can pick from but we chose Heroku for this case because there is a free option that is […]
