Intel® VTune™ Performance Analyzer for Windows* - Time-Based Sampling is Disabled on Itanium® and Itanium 2-Based Systems
Symptom(s): Time-Based Sampling is disabled on Itanium® and Itanium 2-based systems
Cause: The VTune™ analyzer relies on the Windows* HAL (Hardware Abstraction Layer) for TBS (Time-Based Sampling). On Itanium® and Itanium 2-based systems, the HAL uses the Clockticks event, so TBS would be the same as Event-Based Sampling.
Solution: Use EBS (Event-Based Sampling) with the Clockticks event on Itanium® and Itanium 2-based systems.
