Interactive grid computing requires steering of remote parallel applications. On the one hand, the control data stream of a local steering part of a distributed application need to be forwarded onto all involved nodes in the grid. On the other hand, results from the grid need to be collected and sent back to the local application. Interactivity requires that these data streams pass through the network with as little delay as possible. In theory, the amount of time spent for computation and transmission should be below the threshold of human perception. The glogin tool offers interactive connections for the grid and various methods of forwarding network traffic by using interactive connections for remote parallel applications in the grid.
