PAPI 4.4.0 Release with BG/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

PAPI 4.2.1 Release
2012-02-14

The PAPI 4.2.1 release is now available for download.

This is a minor release of PAPI-C. It does not break binary or semantic compatibility with previous versions.

We have reviewed and updated all doxygen generated man pages for documentation, and reworked the output from papi_native_avail and papi_xml_event_info.
We have also added support for AMD Family 11 and 12 processors, and redefined the PAPI_FP_OPS event for Intel SandyBridge so that it only requires 4 counters and can run properly with hyperthreading enabled.
A host of bug fixes and code clean-ups have also been implemented, including significant rewrites of several components for clarity and functionality.

For a summary of changes, read the PAPI 4.2.1 Release Notes.

And for installation instructions read the Installation Notes.
