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...

MAGMA 1.1 is now available. This release extends MAGMA 1.0 by providing the following new functionalities:

Multicore and multi-GPU support;
Non-GPU-resident LU, QR, and Cholesky factorizations;
Tile LU, QR, and Cholesky factorizations and solvers with StarPU dynamic scheduling;
Matrix inversion routines;
LAPACK testing.

MORSE released as MAGMA module

Sun, 13 Nov 2011 23:54:06 GMT

The MORSE module has been released as an extension to the MAGMA library. MAGMA can now handle multicore processors enhanced with multiple GPUs thanks to the StarPU runtime system. Get the flyer and download the code.

PLASMA 2.4.2 Release

Thu, 15 Sep 2011 14:18:44 GMT

PLASMA 2.4.2 has been released.

This package contains:

New version of quark removing active waiting and allowing user to bind tasks to set of cores.
Installer: Fix compatibility issues between plasma-installer and PGI compiler reported on Kraken by A. Bouteiller.
Fix one memory leak with Hwloc.
Introduce a new kernel for the recursive LU operation on tile layout which reduces cache misses.
Fix several bugs and introduce new features thanks to people from Fujitsu and NAG :
- The new LU factorization with partial pivoting introduced in release 2.4 is now working on rectangular matrices.
- Add missing functions to Fortran 77 interface.
- Add a new Fortran 90 interface to all LAPACK and Tile interface. Asynchronous interface and mixed precision routines are not available yet.
- Fix arguments order in header files to fit implementation.

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

MAGMA 1.0 Released

Thu, 25 Aug 2011 06:02:38 GMT

MAGMA 1.0 is now available. This release includes the MAGMA sources! MAGMA 1.0 is intended for a single CUDA enabled NVIDIA GPU. It extends version 0.2 by adding support for the Fermi GPUs (see the sample performances for LU, QR, and Cholesky factorizations and LS solvers in complex arithmetic). For more details see the MAGMA 1.0 Rlease Notes and the MAGMA 1.0 presentation.

Included are routines for the following algorithms:

LU, QR, and Cholesky factorizations in both real and complex arithmetic (single and double);
Hessenberg, bidiagonal, and tridiagonal reductions in both real and complex arithmetic (single and double);
Linear solvers based on LU, QR, and Cholesky in both real and complex arithmetic (single and double);
Eigen and singular value problem solvers in both real and complex arithmetic (single and double);
Generalized Hermitian-definite eigenproblem solvers;
Mixed-precision iterative refinement solvers based on LU, QR, and Cholesky in both real and complex arithmetic;
MAGMA BLAS in real arithmetic (single and double), including gemm, gemv, symv, and trsm.

See the Software section for a download link.

PLASMA 2.4.1 Release

Fri, 08 Jul 2011 12:16:07 GMT

PLASMA 2.4.1 has been released.

This package contains two major bug fix:

Fix bug with Fujitsu compiler reported on the forum
Unbind threads in PLASMA_Finalize to avoid problem of binding in OpenMP section following PLASMA calls (still possible on Mac and AIX without hwloc). A better fix is to create the OpenMP thread in the user code before any call to PLASMA thanks to a fake parallel section.

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

PLASMA 2.4.0 Release

Tue, 14 Jun 2011 15:44:25 GMT

PLASMA 2.4.0 has been released.

This package contains several new important routines:

LAPACK-compliant LU factorization,
symmetric eigenvalue problem routines (eigenvalues only, no eigenvectors yet),
singular value decomposition routines (singular values only, no singular vectors yet),
generalized eigenvalue problem routines (symmetric positive definite systems only),
tree-based QR and LQ routines supporting all input parameters Left/Right, NoTrans/Trans/ConjTrans.

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

PAPI 4.1.3 Update

Fri, 13 May 2011 19:34:33 GMT

We had a minor mishap with yesterday's PAPI 4.1.3 tarball. A few changes were inadvertently ommitted. A new tarball was uploaded to the software page at 3:30 ET today (Friday). If you downloaded PAPI 4.1.3 yesterday or this morning, you may want to download a new copy.

Thanks,
