For many years, threading was a subject that was ignored by the standards, but starting in 2011, the new editions of C and C++ described a portable thread model. The biggest addition was not with threading itself, but with the details of shared memory. Different architectures handle shared memory very differently, so an old approach that worked fine on the Intel Architecture may fall flat on ARMv8 or QorIQ.

Fortunately, the new standards added a portable programming API for doing shared memory and inter-thread synchronization that works regardless of the underlying operating system. In this session, attendees will learn how to use the new standards to write portable, efficient, and reliable algorithms using shared memory.

Topics include:

• Race conditions and undefined behavior
• Synchronization
• The sequential consistency synchronization model
• The release, acquire, and consume models
• Implementation on different architectures
• Implementation tradeoffs vs. software complexity

An astounding number of internet-connected devices are being developed using a wide array of common networking protocols. At the same time, an increasingly competitive hardware landscape gives the Internet of Things developers many choices when he or she considers what processor to use in the future. Successful companies would like to leverage their existing code base for many years, but this requires that the software is written in a portable manner.

C and C++ are flexible languages, but they are notorious for their many unspecified, implementation defined, and undefined behaviors. This course describes the top source of non-portable code, and discusses coding standards and techniques. This session will minimize the amount of non-portable code. The course will also cover how to use static assertions to alert the programmer about non-portable code before it causes a silent failure.

Much of the technological innovation in IoT is centered on the protocols, standards, and applications needed to enable new capabilities. Security, however, is largely an afterthought. This talk will discuss the security and privacy challenges introduced by IoT and how developers in the IoT world can use security to gain competitive advantage in their designs and their businesses.
