General purpose GPU recently has successfully drawn attention from high-performance computing due to higher core density and lower EPI value than CPU. The newest report of Top500 shows that there are thirty-nine supercomputing systems using GPUs to accelerate data computation: two Chinese systems called Tianhe-1A and Nebulaeare at No. 2 and No. 4 and one Japanese system called Tsubame 2.0 at No. 5 are on this list. Amazon has announced the availability of Cluster GPU Instances for Amazon EC2 to deliver the computational power of GPUs in Clouds. More and more researchers have used GPU clusters instead of CPU clusters for resolving their massive-computation problems such as high energy physics, scientific simulation, data mining, climate forecast, and earthquake prediction. As the impact of GPU on both of the academic and engineering areas is increasing rapidly, many issues of GPU cluster computing have to be addressed further in order for improving and enriching the user experience and applications of GPU cluster computing. For example, the complexity of the GPU programming such as CUDA and OpenCL is too high for users to move their applications towards this new computing platform since these programming interfaces and models are quite different from MPI or OpenMP, which are popularly used in CPU cluster computing. In addition, users lack friendly and efficient tools such as debugger and performance analyzer during the period of program development. On the other hand, the computing systems built on GPU clusters require useful tools in emergence to effectively monitor and manage GPU resources for system throughput and to maintain the QoS and reliability of the execution of user applications. As previously described, this special issue is aimed at providing a forum for researchers to present their innovative design, implementation, and experience in software of GPU cluster computing. We encourage authors to submit high-quality, original, unpublished papers. Potential topics include, but are not limited to:
Together with EuroPar-12, the 5th Workshop on UnConventional High Performance Computing 2012 (UCHPC 2012) will take place on August 27/28 at Rhodes Island, Greece. The workshop tries to capture solutions for HPC which are unconventional today but could become conventional and significant tomorrow. While GPGPU is already used a lot in HPC, there still are all kind of issues around best exploitation and productivity for the programmer. Submission deadline: June 6, 2012. For more details, see
http://www.lrr.in.tum.de/~weidendo/uchpc12. UPDATE: Submission deadline extended to June 11.

In recent years, utilizing Graphics Processing Units for general processing has become a very popular approach to obtain low-cost high performance computing applications. Algorithms from many computer science application domains have been adapted to utilize GPUs to increase the efficiency of processing. Unfortunately, while other application domains strongly benefit from utilizing the GPUs, databases related applications seem not to get enough attention. The main goal of GPUs in Databases workshop is to fill this gap. This event is devoted to sharing the knowledge related to applying GPUs in Database environments and to discuss possible future development of this application domain.
The list of topics includes: data compression on GPU, GPUs in databases and data warehouses, data mining using GPUs, stream processing, applications of GPUs in bioinformatics and data oriented GPU primitives.
Reminder: the deadline to submit a research poster for this year’s GPU Technology Conference is Thursday, February 2, 2012. Selected poster presenters receive a discount to attend GTC. They are required to attend the conference in order to present their work at the GTC Poster Showcase. GTC will be held May 14-17 in San Jose, California. For more information, see the call for participation and call for posters. To submit your poster abstract, visit https://gtc-submissions.confreg.com/.
High Performance Graphics is the leading international forum for performance-oriented graphics systems research including innovative algorithms, efficient implementations, and hardware architecture. The conference brings together researchers, engineers, and architects to discuss the complex interactions of massively parallel hardware, novel programming models, efficient graphics algorithms, and novel applications. High Performance Graphics was founded in 2009 to synthesize and broaden on two important and well-respected conferences in computer graphics: Graphics Hardware and Interactive Ray Tracing.
HPG 2012 is co-sponsored by Eurographics and ACM SIGGRAPH and will take place on June 25-27, is co-located with the Eurographics Symposium on Rendering in Paris, France. We invite original and innovative performance-oriented contributions from all areas of graphics, including hardware architectures, rendering, physics, animation, simulation, and data structures, with topics including (but not limited to): Interactive rendering pipelines (hardware or software); Interactive rendering algorithms (hardware or software); Graphics hardware and systems; Languages and compilation; Parallel computing for graphics; and Mobile graphics. Please see the conference website for the full CFP.

Since the last WCCM (Sydney 2009), where we organized a similarly themed minisymposium, the scientific and engineering communities have gained much experience in using GPU hardware for their applications. The number of publications addressing GPU applications has skyrocketed, while researchers have developed much common understanding of how to implement numerical methods in this architecture. Moreover, we now find that three of the five fastest computers in the world, as measured for the Top500 list, are GPU-based systems. There is much conversation about GPUs playing a leading role in the exascale computing world. In summary, this topic is of wide interest; frankly, it is all the rage. This minisymposium will concentrate presentations from the top researchers in the world using GPU hardware for applications in all branches of computational mechanics. We encourage contributions that address innovative methods to use GPUs efficiently, studies in numerical methods as they apply to adapting to the hardware and perspectives on the future of GPUs as we advance toward exascale.
WCCM will be held at São Paolo, Brazil, 8–13 July 2012. The abstract submission deadline is December 31, 2011. More information: http://www.wccm2012.com, http://barbagroup.bu.edu/Barba_group/Events.html.
The 4th Workshop on using Emerging Parallel Architectures (WEPA 2012) is held in conjunction with the International Conference on Computational Science (ICCS 2012), Omaha, Nebraska, June 2-4, 2011.
The computing landscape has undergone significant transformation with the emergence of more powerful processing elements such as GPUs, FPGAs, multi-cores, etc. On the multi-core front, Moore’s Law has transcended beyond the single processor boundary with the prediction that the number of cores will double every 18 months. Going forward, the primary method of gaining processor performance will be through parallelism. Multi-core technology has visibly penetrated the global market. Accordingly to the latest Top500 lists the HPC landscape has evolved from supercomputer systems into large clusters of dual or quad-core processors. Furthermore, GPUs, FPGAs and multi-cores have been shown to be formidable computing alternatives, where certain classes of applications witness more than one order of magnitude improvement over their GPP counterpart. Therefore, future computational science centers will employ resources such as FPGA and GPU architectures to serve as co-processors to offload appropriate compute-intensive portions of applications from the servers.
