Performance prediction component

The global purpose of the PPC tool is to provide performance information about some selected computational kernels when they are executed in a grid. In some cases, this information is just predicted (execution times, communication overheads), in others it is, in fact, real (number of communications, load balance, ...). The predicted data are based on analytical models obtained from exhaustive monitorized measurements.

The kernels that are considered include both applications dependent and general purpose. In addition, the tool includes a Graphical User Interface (GUI) to help the user to establish the features of the grid, and then, to simulate their effects on the target parallel kernels.

Therefore, information about the behaviour of the kernels under different virtual system configurations can be extracted and visualized. This tool can be run in a single workstation or PC, because no grid computations are involved. The end users of this tool are Grid programmers who want to know the behaviour of their programs under different grid scenarios, as well as resource brokers. Another possible use of this tool is in academic institutions to study the way in which grids behave.
