Intel® VTune™ Amplifier supports sampling on up to 4096 processors (CPUs). To focus on specific processors, set processor masking and select processors to monitor for the hardware event-based sampling collection:
- Click the Project Properties button on the VTune Amplifier toolbar. The Project Properties: Target tab opens with the Application to Launch pane active.
- From the Advanced section, configure the CPU mask option to collect data on the processors with the specified numbers and/or specified ranges. For example, specify "2-8, 10, 12-14" values to sample CPUs 2 through 8, 10, and 12 through 14.
