SkelCL: enhancing OpenCL for high-level programming of multi-GPU systems [PDF]

, 2013
Application development for modern high-performance systems with Graphics Processing Units (GPUs) currently relies on low-level programming approaches like CUDA and OpenCL, which leads to complex, lengthy and error-prone programs.

Study on the Kinematic Performances and Optimization for Three Types of Parallel Manipulators

Machines, 2016
The modelling, optimization issues and stiffness for several types of three degrees-of-freedom parallel robotic manipulators, i.e., 3-DOF pure translational, 3-DOF pure rotational and 3-DOF mixed motion types, are studied in this paper. First of all, the

Parallel electric fields are inefficient drivers of energetic electrons in magnetic reconnection

, 2016
We present two-dimensional kinetic simulations, with a broad range of initial guide fields, that isolate the role of parallel electric fields ($E_\parallel$) in energetic electron production during collisionless magnetic reconnection. In the strong guide
