Efficient High Performance Computing on Heterogeneous Platforms

Heterogeneous platforms are mixes of different processing units in a compute node (e.g., CPUs+GPUs, CPU+MICs) or a chip package (e.g., APUs). This type of platforms keeps gaining popularity in various computer systems ranging from supercomputers to mobile devices. In this context, improving their efficiency and usability has become increasingly...

Towards a Systematic Exploration of the Optimization Space for Many-Core Processors

The architecture diversity of many-core processors - with their different types of cores, and memory hierarchies - makes the old model of reprogramming every application for every platform infeasible. Therefore, inter-platform portability has become a desirable feature of programming models. While functional portability is ensured by standards...
