IVF Performance Profiling

carmanj — Tue, 13 Jul 2004 23:14:02 GMT

Excuse me if this is a redundant question, but I've been away from the forums for a while and now need to use the new IVF for a project.We are attempting to "tune"a compute-intensive algorithm and measure trade-offs between various approaches as well asREAL*4 vs REAL*8 math (performance vs precision).

I used the old CVF performance profiler successfully earlier and wondered how to do the same with IVF. I've looked at VTune info, but don't see that it is analogous to the old profiler - looks like it gives system-wide results that would be hard to disentangle from the application under study.

Any suggestions would be helpful.

Thanks

VTune is exactly what you want. It is FAR superior to the MS Profiler. Give it a try.

I am looking at VTune for profiling our Fortran code- but we already have Compuware's DevPartner, how does VTune stack up against this for IVF?

i'm not familiar with that. You can download a free trial of VTune and try it for yourself. Do use the tutorials, as VTune can seem intimidating at first.
