I am using Vtune 3.0 on RedHat 3, Update 5. The 2 processors are Itanium 2's.
vtl activity run1 -c sampling -o "-ec en=CPU_CYCLES" -d 20 -app ./a.out,"args" run
vtl view | more
The view says that Module vmlinux, Process pid0x0 is taking roughly 98% of the CPU cycles, even though my app is CPU intensive and runs 20 seconds.
When I took the "Tuning for the Intel Itanium 2 Microarchitecture", I didn't have this problem.
I do not have a Windows workstation connected to the Linux box, so I must use the vtl interface.
