In performance-critical applications such as scientific computing, graphics, game development, or data processing, converting large arrays of floating-point numbers to integers is a common operation. While a basic scalar loop...
When working with numerical data, a common task is to convert arrays of integers into arrays of floating-point numbers. Although the basic scalar approach works perfectly fine, it may not...
The nvme-cli is a command line tool used to manage and interact with NVMe (Non-Volatile Memory Express) storage devices - like NVMe SSDs - on Linux systems. It gives you...
When working with Linux systems - especially when dealing with performance tuning, hardware compatibility, or security updates - it can be important to know which microcode version the CPU is...
When you're optimizing code for performance, especially in C or C++, using compiler options like -march=native can significantly boost speed by enabling all the SIMD instruction sets and CPU-specific optimizations...
When building modern C or C++ projects, it's common to want to use the latest compiler features and optimizations. But not all compilers - or even versions of the same...
The cpuid is a command line tool that lets you query and display detailed CPU information directly from the CPUID instruction - without needing to write any code. This tutorial...
Compiler warnings help developers write cleaner, safer, and more maintainable code. They help catch potential bugs early, enforce good practices, and improve code quality. But unless explicitly enabled, many compilers...
When we usually compile a C or C++ program, we just run a single command like gcc main.c -o test, and we have an executable. The compiler doesn't magically transform...
