DVDraw

 

 

A shared white board based on Distview

 

 

    DVDraw or Distview Draw is a shared white board utility developed for the Upper Atmospheric Research Collaboratory, or UARC.

     

    Started in 1992 UARC has become one of the Internet's premier collaborative research efforts. This is the setup: space physics researchers around the world can sit down to their computers in the comfort of their offices and call up a screen that allows them to control and gather data from more than a dozen instruments located around--and above--the globe. Along with this smorgasbord of live data comes direct access to the most advanced supercomputer models of upper atmospheric phenomena, and a set of state-of-the-art communication tools, including ''chat rooms'' and a shared white-board utility. And all of this is recorded for replay, annotation, or asynchronous collaboration.

    The first part of this paper is a short user manual for DVDraw. It takes the form of a FAQ (frequently asked questions) and describes all the operations that one can perform with DVDraw.

     

    In the second part, some of DVDraw's internals are described. State replication and concurrency control are being discussed.
