https://community.intel.com/t5/Software-Archive/Performance-problem/m-p/951676#M19746 Hi, <BR />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. <BR />The compilation was no big problem and the program works. <BR />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?). <BR />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. <BR />Any ideas? Please help me!!! <BR /> <BR />Kurt Thu, 17 May 2001 21:49:25 GMT Intel_C_Intel 2001-05-17T21:49:25Z https://community.intel.com/t5/Software-Archive/Performance-problem/m-p/951676#M19746 Hi, <BR />we are using a simulation program that we got with source code and added lots of own routines.
