we are using a simulation program that we got with source code and added lots of own routines. It always used to work fine under HP-UX and I`m just trying to port it to Tru64.
The compilation was no big problem and the program works.
But, as the program starts to process out own routines, the performance falls under 1 percent and raises up to the normal rate again when leaving. This only happens when running in the foreground (Problem with graphics?).
What is a good way to find the bottleneck? I think that a profiler can't help in this case because I require the amount of real time for every routine.
Any ideas? Please help me!!!
