C++ on its way to exascale and beyond

The High Performance Computing (HPC) community is facing a technology shift which will result in a performance boost by three orders of magnitudes within the next 5 years. This rise of performance will mainly be acquainted by increasing the level of concurrency in such a way that a user of those systems needs to accommodate to billion way parallelism. The main problems to solve are: Programmability, Portability, Energy Saving and Resiliency. The author believes that leveraging modern C++ will lead to a possible solution to those problems from a software perspective.

This talk will discuss the use of C++ in such a massively parallel environment: Extending a future based API to present a lightweight and efficient mechanism to support massively parallel, multi-way parallelism.

The question of what's beyond such extreme scales is hard to answer. However, we will always see a dissemination of today's HPC architectures into tomorrow's end-consumer devices or even embedded systems. A brief outlook on how to benefit from HPC technology to the other end of the spectrum will be given and the loop will be closed by pointing out several similarities.
