A Survey of Methods for Analyzing and Improving GPU Energy Efficiency

February 10th, 2015


Recent years have witnessed a phenomenal growth in the computational capabilities and applications of GPUs. However, this trend has also led to dramatic increase in their power consumption. This paper surveys research works on analyzing and improving energy efficiency of GPUs. It also provides a classification of these techniques on the basis of their main research idea. Further, it attempts to synthesize research works which compare energy efficiency of GPUs with other computing systems, e.g. FPGAs and CPUs. The aim of this survey is to provide researchers with knowledge of state-of-the-art in GPU power management and motivate them to architect highly energy-efficient GPUs of tomorrow.

CfP: Optimization of Parallel Scientific Applications with Accelerated HPC

October 29th, 2014

Since 2011, the most powerful supercomputers systems ranked in the Top500 list have been hybrid systems composed of thousands of nodes that includes CPUs and accelerators, as Xeon Phi and GPUs. Programming and deploying applications on those systems is still a challenge due to complexity of the system and the need to mix several programming interfaces (MPI, CUDA, Intel Xeon Phi) in the same application. This special issue of the International Journal of Computers & Electrical Engineering is aimed at exploring the state of the art of developing applications in accelerated massive HPC architectures, including practical issues of hybrid usage models with MPI, OpenMP, and other accelerators programming models. The idea is to publish novel work on the use of available programming interfaces (MPI, CUDA, Intel Xeon Phi) and tools for code development, application performance optimizations, application deployment on accelerated systems, as well as the advantages and limitations of accelerated HPC systems. Experiences with real-world applications, including scientific computing, numerical simulations, healthcare, energy, data-analysis, etc. are also encouraged.

CfP: GPGPU 2015

October 29th, 2014

The goal of this workshop is to provide a forum to discuss new and emerging general-purpose purpose programming environments and platforms, as well as evaluate applications that have been able to harness the horsepower provided by these platforms. This year’s work is particularly interested on new heterogeneous GPU platforms, new forms of concurrency, and novel/irregular applications that can leverage these platforms. Papers are being sought on many aspects of GPUs, including (but not limited to): Read the rest of this entry »

CfP: International Workshop on Data (Co-)Processing on Heterogeneous Hardware DAPHNE 2015

October 8th, 2014

The goal of this one-day workshop is to investigate challenges and opportunities for data processing on existing and upcoming heterogeneous hardware architectures. The workshop is co-located  to EDBT/ICDT 2015, March 23-27, Brussels, Belgium, and more information is available at

Increased heterogeneity is one of the major current challenges in data processing on modern hardware. With multi-core CPUs, graphics cards, massively parallel accelerator cards (e.g. Intel Xeon Phi), heterogeneous mobile processors (e.g. ARM big.LITTLE) and FPGAs, we already face a huge variety of available processing devices with different capabilities, strengths and weaknesses. This trend is expected to accelerate in the near future, and tomorrow’s database systems will need to exploit and embrace this increased heterogeneity in order to keep up with the performance requirements of the modern information society.

Call for Contributions: GPU algorithms for image processing and computer vision

July 22nd, 2014

“GPU Algorithms for Image Processing and Computer Vision”, to be published by Springer, will contain a collection of articles on fundamental image processing and computer vision methods adapted for Graphics Processing Units (GPUs). In recent years, substantial efforts were undertaken to adapt many such algorithms for massively-parallel GPU-based systems. The book is envisioned as a consolidation of such work into a single volume covering widely used methods and techniques. Each chapter will be written by authors working on a specific group of methods. It will provide mathematical background, parallel algorithm, and implementation details leading to reusable, adaptable, and scalable code fragments. The book will serve as a GPU implementation manual for many image processing and analysis algorithms providing valuable insights into parallelization strategies for GPUs as well as ready-to-use code fragments with a broad appeal to both developers and researchers interested in GPU computing.

CfP: GPU in High Energy Physics 2014

June 3rd, 2014

The conference focuses on the application of GPUs in High Energy Physics (HEP), expanding on the trend of previous workshops on the topic and pointing to establishing a recurrent series. The emerging paradigm of the use of graphic processors as powerful accelerators in data- and computation-intensive applications found fertile ground in the computing challenges of the HEP community and is currently object of active investigations. This follows a long established trend which sees the increased use of cheap off-the-shelf commercial units to achieve unprecedented performances in parallel data processing, thus leveraging on a very strong commitment of hardware producers to the huge market of computer graphics and games. These hardware advances comes together with the continuous development of proprietary and free software to expose the raw computing power of GPUs for general-purpose applications and scientific computing in particular. All different applications of massively parallel computing in HEP will be addressed, from computational speed-ups in online and offline data selection and analysis to hard real-time applications in low-level triggering, to MonteCarlo simulations for lattice QCD. Both current activities and plans for foreseen experiments and projects will be discussed, together with perspectives on the evolution of the hardware and software.

The conference is held in Pisa (Italy), 10.9.2014 – 12.9.2014. More information:

CfP: Workshop on Heterogeneous and Unconventional Cluster Architectures and Applications (HUCAA2014)

March 28th, 2014

The workshop on Heterogeneous and Unconventional Cluster Architectures and Applications, held in conjunction with ICPP 2014, September 9-12, 2014, Minneapolis, MN, USA, gears to gather recent work on heterogeneous and unconventional cluster architectures and applications, which might have a big impact on future cluster architectures. This includes any cluster architecture that is not based on the usual commodity components and therefore makes use of some special hard- or software elements, or that is used for very special and unconventional applications. In particular we call for GPUs and other accelerators (Intel MIC/Xeon Phi, FPGA) used at cluster level. Other examples include virtualization, in-memory storage, hard- and software interactions, run-times, databases, and device-to-device communication. We are in particular encouraging work on disruptive approaches, which may show inferior performance today but can already point out their performance potential. The broad scope of the workshop facilitates submissions on unconventional uses of hardware or software, gearing to gather ideas that are coming to life now and not limiting them except for their context: clusters. Also, these proposals may rather be reflective of a broader industry trend.

We are seeking new proposals presented from a holistic perspective. In this regard, one of the aims of the workshop is anticipating the evolution of clusters. Instead of just presenting new work carried out in the traditional cluster areas usually addressed in other conferences and workshops, we are thinking on creating the right atmosphere for a discussion of opportunities in cluster computing. In this regard, contributions would not only be accepted according to their technical merits but also according to their contribution to this discussion.
