Announcing PAPI 6.0.0
2020-03-04

PAPI 6.0.0 was released March 4, 2020. This release includes a new API for SDEs (Software Defined Events), a major revision of the 'high-level API', and several new components, including ROCM and ROCM_SMI (for AMD GPUs), powercap_ppc and sensors_ppc (for IBM Power9 and later), SDE, and the IO component (exposes I/O statistics exported by the Linux kernel). Furthermore, PAPI 6.0 ships CAT, a new Counter Analysis Toolkit that assists with native performance counter disambiguation through micro-benchmarks.

The PAPI release can be downloaded from https://bitbucket.org/icl/papi/wiki/PAPI-Releases or http://icl.utk.edu/papi/software.

Announcing PAPI 5.7.0
2019-03-04

PAPI 5.7 is now available. This release includes a new component, called "pcp", which interfaces to the Performance Co-Pilot (PCP). It enables PAPI users to monitor IBM POWER9 hardware performance events, particularly shared “NEST” events without root access.

This release also upgrades the (to date read-only) PAPI “nvml” component with write access to the information and controls exposed via the NVIDIA Management Library. The PAPI “nvml” component now supports both---measuring and capping power usage---on recent NVIDIA GPU architectures (e.g. V100).

We have added power monitoring as well as PMU support for recent Intel architectures such as Cascade Lake, Kaby Lake, Skylake, and Knights Mill (KNM). Furthermore, measuring power usage for AMD Fam17h chips is now available via the “rapl” component.

The PAPI release can be downloaded from http://icl.utk.edu/papi/software.

Announcing PAPI 5.6.0
2017-12-20

PAPI 5.6.0 contains a major cleanup of the source code and the build system to have consistent code structure, eliminate errors, and reduce redundancies.  A number of validation tests have been added to PAPI to verify the PAPI preset events.  Improvements and changes to multiple PAPI components have been made, varying from supporting new events to fixes in the component testing. 

For specific and detailed information on changes made in this release, see ChangeLogP560.txt for keywords of interest or go directly to the PAPI git repository.

Acknowledgements: This release is the result of efforts from many people, with special Thanks to Vince Weaver, Phil Mucci, Steve Kauffman, William Cohen, Will Schmidt, and Stephane Eranian (for libpfm4) from the internal PAPI team.

The PAPI release can be downloaded from http://icl.utk.edu/papi/software.


Announcing PAPI 5.5.1
2016-11-18

This is a point release intended primarily to add support for uncore performance monitoring events on Intel Xeon Phi Knights Landing (KNL).  Other minor bugfixes have also been made.

For specific and detailed information on changes made in this release, see ChangeLogP551.txt for keywords of interest or go directly to the PAPI git repository.

As always, a very large Thank You goes out to all our collaborators and contributors!  This project would not be successful without your help!

Announcing PAPI 5.5.0
2016-09-14

PAPI 5.5 is now available. This release includes a new component that provides read and write access to the information and controls exposed via the Linux powercap interface.The PAPI powercap component supports measuring and capping power usage on recent Intel architectures.

We have added core support for Knights Landing (uncore support will be released later) as well as power monitoring via the RAPL and powercap components. 

As always, a very large Thank You goes out to all our collaborators and contributors!  This project would not be successful without your help!

The PAPI release can be downloaded from http://icl.cs.utk.edu/papi/software.
