Current parallel platforms are increasingly equipped with additional accelerators leading to hybrid system architectures. Parallel applications for these platforms can be implemented using a task-based programming approach. Such an approach facilitates the exploitation of all available execution units including the processor cores and the accelerators. The execution of a task-based application requires scheduling decisions, which may be provided by a suitable scheduling tool. This article discusses the extensions of the scheduling toolkit SEParAT to support hybrid cluster architectures. In particular, it first defines the extended programming model for hybrid platforms and the corresponding scheduling problem. The second part of the article describes the integration of this model into SEParAT. A particular focus lies on the extension of SEParAT's input and output interfaces.

—In an increasingly competitive world, the responsiveness has become essential to improve the performance of companies. Accordingly a large number of companies have implemented the Lean approach. This approach is a production management method based on waste elimination and just-in-time production. This leads manufacturers to update and adapt their ways of production management and so reorganize the production lines to reduce costs, minimize delays as well as optimize their flexibility. To do this, the use of the Virtual Reality (VR) in the lines production's simulation would offer many advantages. Thus, this technology would allow users to interact with simulation model in real-time and in a 3D format. However, few works have integrated virtual reality in the field of simulation in Lean manufacturing environment. The objective of this paper is to propose a method of simulation of production flows in a virtual environment in real time. To this end, we will review the traditional industrial tools in the field of production simulation. Then we will present the main advantages of using the VR to the manufacturing processes in a lean environment. Finally a global software solution which integrates VR will be proposed and an example of its application to simulate lines production in VR will be presented.

—Many of researchers working on robotic grasping tasks assume a stationary or fixed object, others have focused on dynamic moving objects using cameras to record images of the moving object and then they treated their images to estimate the position to grasp it. This method is quite difficult, requiring a lot of computing, image processing… Hence, it should be sought more simple handling method. Moreover, the majorities of robotic arms available for humanoid applications are complex to control and yet expensive. In this paper, we are going to detail the requirements to manipulating a 7-DoF WAM robotic arm equipped with the Barrett hand to grasp and handle any moving objects in the 3-D environment in the presence of obstacles and without using the cameras. We used the OpenRAVE simulation environment. We use an extension of RRT-JT algorithm that interleaves exploration using a Rapidly-exploring Random Tree with exploitation using Jacobian-based gradient descent to control the 7-DoF WAM robotic arm to avoid the obstacles, track a moving object, and grasp planning. We present results in which a moving mug is tracked, stably grasped with a maximum rate of success in a reasonable time and picked up by the Barret hand to a desired position.

End-user satisfaction and individual performance have been identified by many researchers as critical determinants of the success of information systems. As an escalating number of organizations now utilize e-procurement systems, there is a desire to understand their effect on individual end-user’s performance. Therefore, this research attempts to empirically examine a framework identifying the relationships between end-user satisfaction, and individual end-user performance, in addition to assessing the impact of three proposed antecedents of end-user satisfaction: processing, content and usability. Data gathered from 432 end-users of ePerolehan system in the Malaysian government agencies were utilized to examine the relationships proposed in the framework using the Partial least square (PLS) approach. The findings provide strong support for our model. Our results indicate three factors processing, content and usability significantly affect end-user satisfaction, while the higher levels of end-user satisfaction leads to improved individual performance.
