I created and run the following sampling activity:
vtl activity MispredictionPenalty-OO-2 -d 100000 -c sampling -o "-sterm yes -ec en=RESOURCE_STALLS.BR_MISS_CLEAR en=CPU_CLK_UNHALTED.CORE" -app ./perlbmk_peak.lnx32-icc-91-fast-g,"-I. -I./lib makerand.pl > makerand.out 2> makerand.err" -moi ./perlbmk_peak.lnx32-icc-91-fast-g run
when I view the results I only get the process name and the process path for the kernel module (vmlinux-2.6.18-1.2798.fc6). How can I get the process name and paths for the other processes, including the application that I'm interested in.

What is PTU, and where can I find the WhatIf forum?
Thanks again

I find I must run insmod-vtune after each reboot, and rebuild vtune driver after each kernel update. PTU shares license and VTune driver with a recent VTune version.
