2013-01-16

Well, it's really PAPI 5.1.0.2, but who's counting?
A few final last minute fixes caused us to bump the version number, just to keep the source code repository happy.

Minor Release, Major Impact
2012-09-20

PAPI 5.0.1 is now available both as a tarball and as a patch to the recent 5.0.0 release. We recommend that all users and tools upgrade to this release.

Why, you may ask, are we releasing again so soon after the 5.0 release?

Primarily because we discovered a bug that randomly causes derived PRESET events to be computed incorrectly. This is a small fix with big implications, and was reported by an early PAPI 5.0 user in our bug reports forum. Thank you for helping to improve our package.

PAPI 5.0.0 (AKA PAPI-V) Now Available
2012-08-24

The PAPI 5.0.0 release is now available for download.

This is a major release of PAPI. Parts of both the internal component and external low-level interfaces have changed. This will break your 4.4 compliant components and links to shared libraries.

Although we have tried to keep the impact of these changes minimal, we have made changes to the Application Binary Interface, the Application Programming Interface, and the Component Development Interface.

PAPI 4.4.0 with Blue Gene Q support
2012-04-19

The PAPI 4.4.0 release is now available for download.
The title says it all -- or almost.

This is a major release of PAPI-C. Not because it breaks compatibility with previous versions. It doesn't. But because it adds support for IBM's latest Blue Gene machine, the BG/Q. That may not matter to most of our users, but to those for whom it matters, it matters a lot.

This effort is the product of a three year collaborative development effort between IBM and the performance tools community. They are to be commended for spear-heading this effort to get it right.

You may notice that we bumped the release version from 4.2.1 to 4.4.0. Because we could. And because it helps Cray, another one of our development partners, keep their versioning consistent. You didn't miss 4.3. We just skipped it.

In addition to the new BG/Q support, we have incorporated a handful of bug fixes, code clean-ups and library updates.

And oh, by the way, this is the first release from our git repository. We think we got it right, but let us know if you see any anomalies.

Bug fixes include:

  * Fix buffer overrun in lmsensors component 
  * libpfm4: Update to current git libpfm4 snapshot
  * Fix broken Pentium 4 Prescott support we were missing the netbusrt_p
    declaration in papi_events.csv
  * Fix various locking issues in the threaded code.
  * Fix multiplexing of large eventsets on perf_events systems.
    This presented when using more than 31 multiplexed events on perf_event 


'Git' thee behind us, CVS!
2012-02-22

Sorry for the bad pun.
We wanted to get your attention to announce a good change.
PAPI has made the switch from the venerable CVS source code repository to Linus Torvalds wonderful new git source code repository. To learn more about using git with PAPI, check out the new git section of our FAQ.
