PEGPUM 2018 Deadline extended!

The deadline for paper submission for the PEGPUM 2018 workshop at HiPEAC 2018 in Manchester has been extended to the 4th of December. We invite you to submit original and unpublished 6-page papers or 2-page extended abstracts.

LPGPU2 paper accepted at DATE 2018 conference

The paper “Optimal DC/AC Data Bus Inversion Coding” by Jan Lucas, Sohan Lal and Ben Juurlink has been accepted as regular paper at the DATE 2018 conference. In the paper a new method for data encoding is presented that reduces the energy consumption of the data transfer between CPU or GPU by up to 6%.  DATE (Design, Automation and Test in Europe) will held in March at the International Congress Center Dresden. The selection process was very competitive with an acceptance rate of regular papers of only 23.7%.

PEGPUM 2017

hipeac.ee8834089c88The “Power-Efficient GPU and heterogeneous Multi-/Many-core Computing” (PEGPUM) workshop has been accepted for inclusion in the HiPEAC event in 2017. The workshop will be held on January 24, 2017 in Stockholm, Sweden, co-located with the HiPEAC conference (https://www.hipeac.net/2017/stockholm/). This will be the 5th PEGPUM workshop, after PEGPUM 2013, PEGPUM 2014, PEGPUM 2015, and PEGPUM 2016. Previous editions of PEGPUM were organized by the LPGPU and LPGPU2 consortia. Next year’s editions will be co-organized with four other European projects targeted at improving the power efficiency of GPUs and heterogeneous multi-/many-core systems: Tulipp, SAFEPOWER, Hercules, and Eyes of Things. Stay tuned for more information!

f2f meeting in Athens

lpgpu_athensThe LPGPU2 consortium had a very successful face-to-face meeting in Athens on June 15 and June 16, 2016. The main topic was the design and implementation of the power analysis, visualization, and improvement framework. Present at the meeting were Ben Juurlink and Jan Lucas from TUB, Andrew Richards, Luke Iwanski, Mehdi Goli from Codeplay, Georgios Keramidas, Iakovos Stamoulis, Mixalis Koziotis, and Panagiotis Apostolou from Think Silicon, Graham Mudd, Philip Harmer, and Prashant Sharma from Samsung, and Mauricio Alvarez-Mesa from Spin Digital.

Paper accepted at MASCOTS 2016

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.

PEGPUM 2016 Workshop

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.

Paper accepted in ACM TACO

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).
