With memory pages shared among applications, sometimes it’s hard to tell how much you’ll really save by killing that memory hog. Two new memory metrics offer help for busy administrators. Anybody who ...

The CPU and the GPU share access to some pages of memory. New Linux code helps the kernel keep track of memory holding data for the GPU. The management of video hardware has long been an area of ...

The following excerpt is from chapter 3, User-Level Memory Management, of Arnold Robbins’ book Linux Programming by Example: The Fundamentals, Prentice Hall PTR; (April 12, 2004), used with permission ...

Methods for the reduction of address space are not new to software engineering. Hashing is a software technique for mapping a vector input into a lower-dimensional vector output. Suppose the goal is ...

The dawn of GPU computing came about in large part due to the immense gap in compute performance between traditional CPUs and programmable GPUs. Whereas CPUs excel with serial workloads, modern GPUs ...

If you’re running any amount of compute infrastructure, you’ve already got a lot of “software-defined” things to help squeeze the most out of your hardware and networking. You’re running virtual ...

In the first installment of this series we had a brief look at the steps needed to get a bare-metal application running on an STM32 microcontroller. While this allowed us to quickly get to the juicy ...

Before I get started, I want to point out that this article makes a couple of assumptions. First, I am assuming that you are running either Windows 2000, Windows XP, or Windows Server 2003 on a 32-bit ...
