The RETAVIC project

Environment description

The DROPS was chosen as our environmental real-time operating system. It will run on very powerful machine that will be called by our department MultiMonster (see also "MultiMonster - a new story").

DROPS

DROPS is a real-time operating system designed at the Technical University of Dresden in order to support real-time application with quality-of-service requirements, especially continuous-media applications.

MultiMonster

Initially the MultiMonster was meant only for the physical equipment used by RETAVIC. However, thanks to the interest of Marc Issler, Jörg Meier and Holger Velke (students of FAU) in team work on multimedia, we've decided to initiate a new project (for more info check "MultiMonster - a new story")

Server for RETAVIC

Since end of 2003, we've installed the very powerful server on our department. The MultiMonster is a cluster build of one queen bee and 12 bees. Below is architecture overview (logical schema), some pictures of the installed hardware and detailed specification of equipment.
