This is a very interesting thing, that VTune Analyzer can't allocate memory for sampling buffer?

I have following questions:

1. Isthis problem for Fedora* 12 or Ubuntu* 9.xx specific?

2. Ifthe user doesn'tinstall nvidia driver, the problem exists or Not?

3.Can this problembe repeated on Fedora* 12? Caused by new kernel?

I suggest to reduce sampling buffer use -
a. vtl global-options buffer-size-KB="10240" ; my defaultvalue is "131072", change to 10MB
b. vtl activity -c sampling your-app run

Regards, Peter
