Cluster Setup
Hardware Configuration
BARC has been into high-performance computing since the early 1990\'s and their ANUPAM series of supercomputers have always been amongst the fastest ones in India.
The need of faster processing and lesser computational times is always the prime requirement of any organization, and BARC produces faster and bigger clusters every 5 years.
The New Computer Center was inaugurated in November 2005 and some of the clusters housed there are -
Operating Systems used are:
Applications
For the tiled display wall, a generic movie player was written, with the GUI done in Qt. The movie player supported display of images, movies and simulations on the tiled display. A plugin based development approach was used.
Image Display
Library Used: OpenGL
Video Display
Library Used: FFMPEG
Proper synchronization was realized in Image/Video display by making the nodes acknowledge the receipt of the image/video frame before swapping the surfaces.
Panning, zooming operations were implemented and proper scaling techniques were used to maintain the aspect ratio of the image/video.
The X11 Desktop was displayed on the tiled display using the VNC server and VNC client technique.
