Supports performance measurement, modelling, tuning and visualisation. Incorporates waiting time analysis which explains the source of waiting times in terms of underlying causes. The visualisation tool also presents the source code in a window to help relate the source code to the measurements. It has been installed at the Cornell Theory Center and should be more widely available soon. The performance analysis is done in the form of experiments with the program being altered to investigate efficiency etc.
Output is both graphical and tabular, howing both profiling and system data.
The analysis is done on a per process basis. This is a monitoring and steering system with low monitoring latency and perturbation. Falcon steering enables you to modify your program while it is executing. Not yet available for public release. The visualisation software for Pablo draws on the data flow metaphor used in AVS and SGI Explorer.
