Parallelizing the cellular potts model on GPU and multi-core CPU: An OpenCL cross-platform study
In this paper, we present the analysis and development of a cross-platform OpenCL parallelization of the Cellular Potts Model (CPM). In general, the evolution of the CPM is time-consuming. Using data-parallel programming model such as CUDA can accelerate the process, but it is highly dependent on the hardware type and manufacturer. Recently, OpenCL has attracted […]

High-Level Programming Framework for Executing Streaming Applications on Heterogeneous OpenCL Platforms
As the computer industry is reaching more and more limits regarding processor speed and transistor size, they have to come up with complex new architectures and more efficient use of the available processing power. For application developers this can be a difficult task, because they have to be aware of low-level hardware properties and there […]

Kd-tree Based N-Body Simulations with Volume-Mass Heuristic on the GPU
N-body simulations represent an important class of numerical simulations in order to study a wide range of physical phenomena for which researchers demand fast and accurate implementations. Due to the computational complexity, simple brute-force methods to solve the long-distance interaction between bodies can only be used for small-scale simulations. Smarter approaches utilize neighbor lists, tree […]

Fast Galactic Structure Finding using Graphics Processing Units
Cosmological simulations are used by astronomers to investigate large scale structure formation and galaxy evolution. Structure finding, that is, the discovery of gravitationally-bound objects such as dark matter halos, is a crucial step in many such simulations. During recent years, advancing computational capacity has lead to halo-finders needing to manage increasingly larger simulations. As a […]

Increasing Deep Neural Network Acoustic Model Size for Large Vocabulary Continuous Speech Recognition
Deep neural networks (DNNs) are now a central component of nearly all state-of-the-art speech recognition systems. Part of the promise of DNNs is their ability to represent increasingly complex functions as the number of DNN parameters increases. This paper investigates the performance of DNN-based hybrid speech recognition systems as DNN model size and training data […]

The design and verification of Mumax3
We report on the design, verification and performance of mumax3, an open-source GPU-accelerated micromagnetic simulation program. This software solves the time- and space dependent magnetization evolution in nano- to micro scale magnets using a finite-difference discretization. Its high performance and low memory requirements allow for large-scale simulations to be performed in limited time and on […]

Speedup of Micromagnetic Simulations with C++ AMP On Graphics Processing Units
A finite-difference Micromagnetic solver is presented utilizing the C++ Accelerated Massive Parallelism (C++ AMP). The high speed performance of a single Graphics Processing Unit (GPU) is demonstrated compared to a typical CPU-based solver. The speed-up of GPU to CPU is shown to be greater than 100 for problems with larger sizes. This solver is based […]

Performance and Efficiency Analysis of Modern Accelerators: Fine-Grained Parallelism on the Intel Xeon Phi
Supercomputers define the pinnacle of computational power and are an essential tool for solving vast scientific computational problems. They employ increasingly parallel architectures to ever increase their nominal peak performance and to allow them to solve larger problems. Employing the vast amount of computation power is however difficult and optimising for many-core architectures has become […]

Evaluation of DGEMM Implementation on Intel Xeon Phi Coprocessor
In this paper we will present a detailed study of implementing double-precision matrix-matrix multiplication (DGEMM) utilizing the Intel Xeon Phi Coprocessor. We discuss a DGEMM algorithm implementation running "natively" on the coprocessor, minimizing communication with the host CPU. We will run DGEMM across a range of matrix sizes natively as well using Intel Math Kernel […]
