Vtune

[gib]

I just downloaded the Vtune trial package. After failing to get any sense out of it with my own program, I searched here and found Steve's post about running a test with samplesoptimizeint_sin.f90. I created a Console app for int_sin.f90 in Release mode, and set the debug switches as Steve said.

I then do Create New Activity, choose QPA Wizard, accept the defaults (just Collect Sampling Data) and Go.

The program runs (shows output lines) then tells me:

"Failed to create sampling data base. Probably .tb5 files are corrupted or don't exist."

I get the same message with my own program.

I'm using Intel Fortran Compiler Integration for Microsoft Visual Studio 2005, 10.1.3885.2005

Please help!

Ahah! My work machine is set up (not my decision!) with only administrators having write permission on C drive. When I login as administrator I can run Vtune and see useful info. Presumably Vtune is logging data to C drive. Can I tell it to do this somewhere else?

Sorry about replying to my own posts.
I found the Configure>Options screen in VTune. I can change the cache directories to places on the D drive, but interesting things happen when I try to change the Symbol Repository directory, currently on C. If I do this as me, it pretends to let me change it but ignores the command (going back in shows it hasn't changed). If I login as administrator and try to change it, when I hit the Apply button VTune immediately terminates without warning (leaving the directory unchanged). I haven't seen this happen before. Is this a special Intel feature? ;-)

I am going to move this post to the VTune forum where the VTune experts hang out.

So, the immediate shutdown when changing the Symbol Repository is a known issue that, I believe (if my memory serves me correctly) will be fixed in the next release.

The other thing you need to change is the VTUNE_GLOBAL_DIR env. variable. This is the VTune analyzer writes temporary data. Also, check out VTUNE_USER_DIR. This is where project data is stored.

Note: if you are not an Administrator (or in the Administrators group), you may run into other problems. While it is true a Power User can run the VTune analyzer, s/he must be granted a couple of privileges: Profile single process and Profile system performance. This is documented in the Release Notes.
