متن کاملPeriscope: Advanced Techniques for Performance Analysis
Performance analysis of applications on supercomputers require scalable tools. The Periscope environment applies a distributed automatic online analysis and thus scales to thousands of processors. This article gives an overview of the Periscope system, from the performance property specification, via the search process, to the integration with two monitoring systems. We also present first exper...
متن کاملSiper-Virtual Reality Simulator of Periscope
In this paper an application designed to simulate the environment seen in a periscope by means of a virtual reality environment is presented. The application allows full viewing of all objects visible from the periscope, sea, ships, airplanes, etc. With the appropriate hardware (3D mouse and tracking systems) it is possible to navigate into the virtual world and interact with the elements. Each...
