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 ...

Some techies are capable of writing programs in assembler, but all will agree that they are very glad that they don’t need to. More know that they are fully capable of writing programs which manage ...

Persistent memory (PM) used to be the norm when magnetic core memory was ubiquitous, but volatile DRAM now dominates main memory. While non-volatile memory (NVM) is used for booting and application ...

Intel Xeon Phi processors have two features that I believe we will see in more and more designs for HPC systems in the future: high bandwidth memory, and options for subdividing the many cores into ...

The White House has called on the tech industry to adopt memory safe programming languages, eliminating most memory safety vulnerabilities from hardware and software. The report by the Office of the ...

In the previous article, we left off with the basic storage model having its objects first existing as changed in the processor’s cache, then being aged into volatile DRAM memory, often with changes ...

The White House is pushing hardware and software makers to build their products using programming languages with internally-engineered guardrails that prevent hackers from peering into the inner ...
