Decreasing the Number of Memory Accesses: The Compiler’s Secret Life 2/2
We investigate memory loads and stores that the compiler inserts for us without our knowledge: “the compiler’s secret life”. We show that these loads and stores, although necessary for the compiler are not necessary for the correct functioning of our program. And finally, we explain how you can improve the performance of your program by removing them.
Loop Optimizations: interpreting the compiler optimization report
We introduce compiler optimization report, a useful tool if you wish to speed up your program by looking at what the compiler failed to optimize.
Why do programs get slower with time?
We investigate why software gets slower as new features are added or data set grows and what can you do about it.
Flexibility and Performance
In this post we talk about how to write code that is both flexible and fast!
