An Introduction to Flynn's Taxonomy
Flynn's taxonomy forms the basis of modern-day
computing architectures. My latest blog marks the beginning of a blog series on multithreading. 💻✨
Discover SISD, SIMD, MISD, and MIMD architectures. These form the basis of the parallel programming models and are crucial for digging deep into threading fundamentals.

A comprehensive guide to the roofline model
This blog discusses the fundamentals and
complexities of the Roofline performance model. Apart from the theoretical concepts,
a hands-on example based on matrix multiplication in C++ (with all the relevant calculations) is showcased for better understanding.

Compiler Optimizations: Boosting code performance without doing much!
Developers looking to optimize the performance of their C++ code should discover compiler optimizations: a set of very effective C++ flags that improve the code performance without much effort. The only prerequisite is that you know what you're doing. Explore flags suitable for Intel C++ compilers such as -fno-alias, -xHost, -xCORE-AVX512, IPO, etc, with a hands-on showdown on a Jacobi iteration C++ code. My latest blog post talks in detail about a set of very useful compiler flags, compatible with Intel C++ Compiler.
