With the increase in parallelism in response to a stagnation of clock frequencies, software libraries are pushed towards multi-threading. However, there are several different threading approaches out there: The most popular in the C/C++ world are POSIX Threads (pthread), OpenMP, and C++11 threads. Clearly, a good software library does not enforce the use of one particular approach, but is able to deal with (almost) any multi-threading approach. In this blog post I will discuss a possible software library design to achieve this. Continue reading
Intel Edison is a tiny computer (smaller in size than a credit card) targeted at the Internet of Things. Its CPU consists of two Silvermont Atom-CPUs running at 500 MHz and is offered for a price tag of around 70 US dollars. Even though Intel Edison is not designed for high performance computing, the design goal of low power consumption makes it nevertheless interesting to look at from a high performance computing perspective. Let us have a closer look.
