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 →
