Report 5 - Compiling and optimising Laidlaw - my writeup on the research (and other aspects about this scholarship).
And there's a video (produced as part of my scholarship requirements), which can be seen below:
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.
N/A, University of St Andrews/Imperial College London
Hi, I'm Leaderboard. graduated MSc student in Advanced Computing at Imperial College London.
I've graduated from St Andrews in 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.
