Warning: the following directories are network-mounted:

- user data directory (/home/7/sampat)

This may negatively affect VTune performance!

Note: you may set alternative (non-remote) locations for global and user data directories

via VTUNE_GLOBAL_DIR and VTUNE_USER_DIR environment variables..

To suppress this warning run the following command:

It could be written permission for VTUNE_USER_DIR/VTune_GlOBAL_DIR since you install the product on mounted network directory?

1. Please set environment variable VTUNE_USER_DIR and VTUNE_GLOBAL_DIR to local driver - OR -

(not sure if we met other problems...see release notes)

2.I strongly suggest you touninstall/reinstall the product in local driver.

Regards, Peter

While Peter knows far more than I do about VTune, I see a couple of items worth pointing out here:

1) Peter meant to type "drive" rather than "driver" in his response. It is documented in the release notes that network drives don't play nice with Intel's software, so try to keep all of the pieces -- the location of the VTune binary, the executable you wish to analyse, & the workspace -- all on a local drive. Simplicity is always good.

2) Part of your command that is returning the error message you quotereads "vtl -c sampling.command". The "-c" switch defines the kind of collection you wish to do on your executable, & from the error messagevtl does not recognize the option "sampling.command"; try "vtl -c sampling" instead.

vtl furnishes a lot ofuseful information if you run it with the "-help" switch, as well as some examples of how to use it. Have a look there, & see if it gives you some ideas you can use in your current instance.

Also, I suggest you turn the command around and have the VTune analyzer launch the MPI launcher (mpi_run). And, since you are using sampling, you don't even have to have the analyzer launch the app, just start collecting sampling data with an infinite duration ("-d 0"), run your MPI app, then use the ActivityController to stop data collection.

Regards,
