PAPI 5.1.0 Ready for Download

Postby danterpstra » Wed Jan 16, 2013 3:01 pm

We added support for PAPI on the Intel Xeon Phi processor, aka MIC or KNC or Knight's Corner. PAPI cross-compiles on the host and runs on the MIC. Note that this currently requires a kernel patch to the MIC kernel. Details can be found in INSTALL.txt.

We also added a new component to measure power usage on MIC cards. This is a host-based component that provides a selection of power, current and voltage measures.

PAPI now supports measuring uncore events on Intel Sandy Bridge processors, which requires support for a new domain: PAPI_DOM_SUPERVISOR to measure events at the system level.

We added a new API, PAPI_get_eventset_component, which returns the component index of a given eventset and is parallel to the PAPI_get_event_component call introduced in PAPI 5.0.

We improved the papi_command_line utility to print output in a variety of formats, and to display event units if they're available.

Other changes and enhancements include:

  • Various build system fixes.
  • NVML component fixes.
  • ARM Cortex A15 support.
  • Enhanced doxygen formatting for html pages.
  • and a host of miscellaneous bug fixes.
