CfP: Journal of Real-Time Image Processing (JRTIP), Special Issue on Heterogeneous Real-Time Image Processing

April 13th, 2015

Mobile devices, such as phones and tablets, offer a plethora of media-rich applications such as photo and video recording and editing, natural user interfaces and computer vision. Other areas of embedded image systems are characterized by close-to-sensor processing, such as advanced driver assistance systems, mobile scanners, and smart devices used in medical and industrial imaging. This demands highest computing capabilities at stringent resource and power budgets as well as hard real-time constraints.

Future scaling of computing performance mandates dramatically improving energy efficiency of image systems. One recognized trend is to use heterogeneous hardware such as big.LITTLE cores and accelerators such as DSPs, embedded GPUs, FPGAs, or dedicated hardware. Another trend is to use new 3D integrated circuit technologies that allow for tighter integration of compute cores, memory and sensors to reduce communication latency and improve bandwidth, leading to lower energy consumption.

This calls for novel methodologies for designing heterogeneous hardware, as well shielding software developers from growing complexity and allowing them to concentrate on algorithm development rather than on low level implementation details. Read the rest of this entry »

HUCAA2015 CFP: Workshop on Heterogeneous and Unconventional Cluster Architectures and Applications

April 13th, 2015

4th International Workshop on Heterogeneous and Unconventional Cluster Architectures and Applications (HUCAA 2015)
Sept. 8-11, 2015 – Chicago, IL, US
In conjunction with IEEE CLUSTER 2015
IEEE International Conference on Cluster Computing


The workshop on Heterogeneous and Unconventional Cluster Architectures
and Applications gears to gather recent work on heterogeneous and
unconventional cluster architectures and applications, which might
have an impact on future mainstream 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 special and unconventional
applications. Read the rest of this entry »

CFP: 8th Workshop on UnConventional High Performance Computing 2015

April 13th, 2015

Recent issues with the power consumption of conventional HPC hardware results in both new interest in accelerator hardware and in usage of mass-market hardware originally not designed for HPC. The most prominent examples are GPUs, but FPGAs, DSPs and embedded designs are also possible candidates to provide higher power efficiency, as they are used in energy-restriced environments, such as smartphones or tablets. The so-called “dark silicon” forecast, i.e. not all transistors may be active at the same time, may lead to even more specialized hardware in future mass-market products. Exploiting this hardware for HPC can be a worthwhile challenge.

UCHPC is held in conjunction with Euro-Par 2015, August 24/25 in Vienna, Austria. More information,including the full call for papers, submission instructions and important dates:

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: 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.
