<div class="section"><p> Parallel programming is about speeding up <em>wall</em>
|
|
<em>clock</em> time, which is the real time that it takes a program to run.
|
|
Unfortunately, some of the obvious wall clock timing routines provided by operating
|
|
systems do not always work reliably across threads, because the hardware thread
|
|
clocks are not synchronized. The library provides support for timing across threads.
|
|
The routines are wrappers around operating services that we have verified as safe to
|
|
use across threads. </p>
