2 Java provides a convenient way to build flexible graphics interfaces
3 The screendump shows the message passing traffic and status of (36) parallel nodes used in a sorting algorithm
4 In the example, the 36 threads are running the explicit algorithm on the client
5 Alternatively and more generally, the threads are replaying a trace of the program which is or was running on a separate set of nodes
6 If one uses Web Servers to control master parallel computation or more generally integrates Web into computing, these Web servers can naturally feed event traces into Java based display
  • These traces can be real-time or batch
