amplxe: Error: Cannot enable Hardware Event-based Sampling: problem with the driver (sep*/sepdrv*). Check that the driver is running and the driver group is in the current user group list. See "Building and Managing the Sampling Driver" help topic for further details.
The system i am using ths is a 2*6core Intel Xeon E5645. I have disabled SMT. The operating system is Linux kernel 2.6.35
