I just installed the latest release of the Fortran Studio (Compiler, VTune, etc). I'm running in VS 2010.
Code I've been working on for a few months now requires 10 minutes for a VTune hotspot analysis. If I DO NOTHING ELSE but point VS to the previous version of the compiler, recompile and rerun the VTune analysis, it completes in ~ 1.5 minutes. In the old case, the recorded CPU times for the various components sum to what VTune lists as "Total CPU Time" -- about 70 seconds. The greater lapsed time presumably was VTune's overhead and such. The new compiler produces code that is somewhat slower (!), nevertheless the sum of the component times is about what VTune lists as the total CPU time -- However the lapsed time (as reported by VTune and my watch) is 630 seconds. Any ideas? Is this a known, new incompatiblity? What could the new compiler be doing (or not doing) that alters the operation of VTune so drastically.
