PAPI 4.4.0 with Blue Gene Q support

Thu, 19 Apr 2012 10:24:25 GMT

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

clMAGMA 0.1 Beta Released

Wed, 04 Apr 2012 05:12:58 GMT

clMAGMA 0.1 Beta is now available. This release provides OpenCL implementations for MAGMA's one-sided dense matrix factorizations (LU, QR, and Cholesky), and thus extending MAGMA's support to include AMD GPUs. The clMAGMA library dependancies, in particular optimized GPU OpenCL BLAS and CPU optimized BLAS and LAPACK for AMD hardware, can be found in the AMD Accelerated Parallel Processing Math Libraries (APPML). Sample performance results on AMD Tahiti GPU are illustrated on the figures below.

'Git' thee behind us, CVS!

Wed, 22 Feb 2012 20:02:43 GMT

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.

DAGuE / DPLASMA release

Thu, 22 Dec 2011 00:15:55 GMT

1.0 Release Candidate 1 - 1.0.0-rc1	2011-12-21
The DAGuE/DPLASMA Team is pleased to announce the release of DAGuE version 1.0.0-rc1. This release candidate is the first in the row and includes the DAGuE software as well as the DPLASMA dense linear algebra layer. We strongly recommend that all users of previous versions upgrade to 1.0.0-rc1 as soon as possible.

QUARK version 0.9.0 released

Tue, 20 Dec 2011 14:04:23 GMT

The first standalone release of the QUARK runtime environment is available. This release contains the QUARK runtime environment and some simple, minimal examples.

All files are available for download in the Software section of the QUARK site.

PLASMA 2.4.5 Release

Tue, 22 Nov 2011 18:58:31 GMT

PLASMA 2.4.5 has been released.

This package contains:

Add LU inversion functions: PLASMA_zgetri, PLASMA_zgetri_Tile and PLASMA_zgetri_Tile_Async using the recursive parallel panel implementation of LU factorization.
The householder reduction trees for QR and LQ factorizations can now work on general cases and not only on matrices with M multiple of MB.
Matrices generation has been changed in every timing, testing and example files to use a parallel initialization generating a better distribution of the data on the architecture, especially for Tile interface. “numactl” is not required anymore.
Timing routines can now generate DAGs with the --dag option, and traces with --trace option if EZTRACE is present.

All files are available for download in the Software section of the PLASMA site.

Fujitsu : K computer No. 1 in Four Benchmarks at HPC Challenge Awards

Wed, 16 Nov 2011 13:05:52 GMT

The HPC Challenge Awards demonstrate that, in addition to achieving successive top-place rankings on the June and November 2011 editions of the TOP500 list measuring LINPACK computational speed, the K computer is evaluated very highly in all-around performance as a general-purpose supercomputer. The K computer is currently under joint development by RIKEN and Fujitsu. Read more...
