Parallel Processing for Energy Efficiency (PP4EE)

The computer architecture and design research group (CARD) at NTNU together with NTNU HPC-section, ARM Norway and the EMECS Erasmus Mundus study will host a one-day seminar covering topics within supercomputing, computational science, parallel processing, heterogeneous computing and energy efficiency. The programme will have a mix of invited international speakers and presentations from NTNU, and will cover all the main abstraction levels from supercomputer applications down to parallel languages and multicore architectures. The aim of the seminar is to stimulate collaborative research involving partners from several of the institutions and several of the abstraction layers.

The seminar had 81 participants. Thanks to all the presenters, sponsors, co-organizers and all the participants showing interest and taking part in the discussions.
