The paper “ALUPower: Data Dependent Power Consumption in GPUs” by Jan Lucas and Ben Juurlink has been accepted at MASCOTS 2016. It describes in detail how data values influence the power consumption of GPUs and how the power consumption can be modeled.
The MASCOTS conference is a well-established forum for state-of-the-art research on the measurement, modeling, and performance analysis of computer systems and networks. The 24th edition of this conference will take place September 21-23, 2016 in Imperial College Campus, London. The conference will bring together academics and industry practitioners to present and discuss their latest research results. The technical program for the 3-day conference will include keynote talks, refereed full and work-in-progress papers.

The LPGPU2 consortium had a very productive kick-off meeting in Prague on January 21-22, 2016, immediately after the HiPEAC conference. Clockwise from left to right Marco Starace (Samsung), Philip Harmer (Samsung), Prashant Sharma (Samsung), Mehdi Goli (Codeplay), Andrew Richards (Codeplay), Jan Lukas (TU Berlin), Luke Iwanski (Codeplay), Iakovos Stamoulis (Think Silicon), Georgios Keramidas (Think Silicon), Mauricio Alvarez-Mesa (TU Berlin / Spin Digital). Not in the picture but also present were the project coordinator Ben Juurlink (TU Berlin), since he took the photo, and Kit Lam (Samsung), who was probably getting coffee or tea.
The Program of the upcoming PEGPUM 2016 workshop is now online. PEGPUM is now organized by the LPGPU2 project. It will feature 6 talks with speakers from the Industry and Universities. We hope to see you soon at HiPEAC 2016 in Prague.
There wil be a LPGPU2 project. Stay tuned for more information!
The PEGPUM Workshop will return to HIPEAC 2016 in Prague. This is the fourth installment of this successful workshop and will feature many interesting talks. It will be the first workshop of the new LPGPU2 project. Please stay tuned for more news and check out the workshop page.
The paper “Spatiotemporal SIMT and Scalarization for Improving GPU Efficiency” by Lucas et al. has been accepted for publication in ACM TACO (http://dl.acm.org/citation.cfm?id=2811402). Because it is original work, it will also be presented at the yearly HiPEAC conference, which is the premier European network event on topics central to ACM TACO and has been attended by more than 600 scientists in 2015. HiPEAC 2016 will be held in Prague (https://www.hipeac.org/2016/prague).
