The future in your pocket

Patrick Crowley
2008 Computer communication review  
In this article, I argue that there is another trend underway, namely integration, which will have a greater near-term impact on developers of system software and applications.  ...  There is a growing sentiment among academics in computing that a shift to multicore processors in commodity computers will demand that all programmers become parallel programmers.  ...  This poses a challenge for software developers who hope to exploit the lowlevel capabilities of such components, or who hope to develop their own operating systems or other pieces of system software.  ...
