In the quest to make small devices cost effective, manufacturers often need to think about reducing the memory size. One option is to find alternative implementations of the abstract data types (ADTs) ...

Nowadays, high-performance server software (for example, the HTTP accelerator) in most cases runs on multicore machines. Modern hardware could provide 32, 64 or more CPU cores. In such highly ...

The load-average calculation is best thought of as a moving average of processes in Linux's run queue marked running or uninterruptible. The words “thought of” were chosen for a reason: that is how ...

The ubiquity and convenience of smartphones has been a real boon for getting information on the go. I love being able to jump on a Wi-Fi hotspot, catch up on my mail, check my banking balance or read ...

Popular memory-consistency models include x86's process consistency, in which writes from a given CPU are seen in order by all CPUs, and weak consistency, which permits arbitrary reorderings limited ...
