About Leaderboard

Hi, I'm Leaderboard. I'm a fourth year student (Senior Honours) studying Computer Science and Mathematics, and spent my third year abroad at Purdue University (Report 6 on GitHub describes my experience there!). My research interests lie in computer architecture, operating systems and compiler optimisations, and last summer I analysed the effects of compiler optimisations on the run-time performance of different applications. A write-up on this is available at https://github.com/Leader-board/Reports/blob/master/Report%205%20-%20Compiling%20and%20optimising%20Laidlaw.pdf.

In the summer of 2020, I looked at the angle of multithreaded programs, which includes analysing OS schedulers and seeing their run-time impact on performance.

Compiling and optimising - effects of different flags on performance of C(++) applications

It is usually the fact that when a C program is compiled using the /O1, /O2 or with another optimisation setting, the performance increases. But what exactly in that flag makes all the difference? Turns out that the answer is not that obvious.
