There is a visualisation option: a trace report file can be built and then used with the Paj=E9 tool. Paj=E9 is aimed at visualizing parallelized applications. See: http://forge.objectweb.org/projects/paje/ Paj=E9 is a great tool. He is designed to handle large trace file. But, when one has recorded trace events during hours, analyzing the whole trace seems not possible. So, the PTT Paj=E9 extension worked in June 2005, but we have not updated it in June 2006. So features may have disappeared. PTT is not only aimed at finding problems in small multi-threaded applications. It is designed to help understanding a problem that happens rarely or only after hours in a large application: it is possible to stop/start dynamically the collect of events and to extract traces that appeared between 2 dates.
