We describe a thread-modular technique for proving termination of massively parallel GPU kernels. The technique reduces the termination problem for these kernels to a sequential termination problem by abstracting the shared state, and as such allows us to leverage termination analysis techniques for sequential programs. An implementation in KITTeL is able to show termination of […]

Next-generation super-computers containing millions of processors will require weather prediction models be designed and developed by teams of scientists, software engineers, and parallelization experts so they are portable and run efficiently on increasingly diverse HPC systems. The design and performance of the NIM global weather prediction model is described. NIM is a dynamical core designed […]

We develop and implement a concurrent dictionary data structure based on the Log Structured Merge tree (LSM), suitable for current massively parallel GPU architectures. Our GPU LSM is dynamic (mutable) in that it provides fast updates (insertions and deletions). For example, on an NVIDIA K40c GPU we can get an average update rate of 225 […]

We present high performance implementations of the QR and the singular value decomposition of a batch of small matrices hosted on the GPU with applications in the compression of hierarchical matrices. The one-sided Jacobi algorithm is used for its simplicity and inherent parallelism as a building block for the SVD of low rank blocks using […]

With the rise of heterogeneous chips available in the market, where integrated GPU cores and CPU cores reside in the same chip and share a unified memory, it is possible to have better execution schemes for many graph algorithms. Graph algorithms can exhibit producer-consumer behavior, a varying amount of parallelism during execution, and irregularity which […]

Aiming at bringing together researchers and practitioners from academia and industry to exchange technical knowledge and boost technical and educational collaboration activities within the related fields of image and graphics processing, 2018 International Conference on Image and Graphics Processing (ICIGP 2018) will be held in Hong Kong during February 24-26, 2018. It is sponsored by […]

ICBBB conference series held annually to provide an interactive forum for presentation and discussion on Bioscience, Biochemistry and Bioinformatics. The conference welcomes participants from all over the world who are interested in developing professional ties to and/or exploring career opportunities in the region. The conference should serve as an ideal forum to establish relationships from […]

ICVR 2018 will bring together top researchers from Asian Pacific areas, North America, Europe and all around the world to exchange research results and address open issues in all aspects of Virtual Reality. Publication Accepted papers […]

The ICMLC 2018: 2018 10th International Conference on Machine Learning and Computing aims to bring together leading academic scientists, researchers and research scholars to exchange and share their experiences and research results on all aspects of Machine Learning and Computing. It also provides a premier interdisciplinary platform for researchers, practitioners and educators to present and […]

There is growing interest in accelerating irregular data-parallel algorithms on GPUs. These algorithms are typically blocking, so they require fair scheduling. But GPU programming models (e.g. OpenCL) do not mandate fair scheduling, and GPU schedulers are unfair in practice. Current approaches avoid this issue by exploiting scheduling quirks of today’s GPUs in a manner that […]

Recently, field-programmable gate array (FPGA) vendors (such as Altera) have started to address the programmability issues of FPGAs via OpenCL SDKs. In this paper, we analyze the performance of relational database applications on FPGAs using OpenCL. In particular, we study how to improve the performance of data partitioning, which is a very important building block […]
