As a result of the huge performance potential of multi-core microprocessors, HPC infrastructures are rapidly integrating them into their architectures in order to expedite the performance growth of the next generation HPC systems. However, as the number of cores per processor increase to 100 or 1000s of cores, they are posing revolutionary challenges to the various aspects of the software stack. In the authors' research, they endeavor to investigate novel solutions to the problem of extracting high-performance. In this paper, they advocate for the use of virtualization as an alternative approach to the traditional operating systems for the next generation multicore-based HPC systems.
