When working with C or C++ code, it can be helpful to know what macros (via #define) the gcc or g++ compiler defines automatically. These predefined macros give you insight...

In heterogeneous environments that span multiple CPU architectures (e.g. x86_64, ARM), identifying the architecture of Docker images is an essential step for ensuring reliable builds and deployments. This is especially...

If you're learning how programs are translated into low-level instructions, or just curious about what the C or C++ code looks like at the assembly level, you can easily generate...

When working with big datasets on a GPU, it's helpful to keep values within a certain range. This process, called clamping, can be done quickly using parallel computing. It helps...

In many high-performance computing tasks - such as data preprocessing, graphics, or scientific simulations - we often need to perform operations on arrays, such as division by a scalar value...

When handling massive datasets or performance-intensive programs, speed and efficiency are essential. A frequently encountered task in such contexts is adding arrays together by summing each element with its counterpart...

Understanding and optimizing system startup performance is a key responsibility for any system administrator, especially in environments where uptime and responsiveness are critical. Slow boot times can signal underlying problems...

When you're working with terminal windows, shell scripts, and background tasks, it's easy to miss what's going on - especially if you're multitasking or running long commands. That's where desktop...

Graphics Processing Units (GPUs) are no longer just for gaming or visual effects - they're now crucial for tasks like machine learning, scientific computing, and video editing. If you use...

The clinfo is a command line tool that displays detailed information about the OpenCL platforms and devices (CPU, GPU, etc.) available on a system. This tutorial explains how to install...
