MAGMA 2.5.2
2019-11-24

MAGMA 2.5.2 is now released. Updates include:

  • New routine: magmablas_hgemm_batched for fixed size batched matrix multiplication in FP16 using the Tensor Cores.
    The routine does not currently support pre-Volta GPUs.
    The routine outperforms cuBLAS for sizes less than 100, as well as for general sizes that are not multiple of 8.
    The kernel is tuned for the notrans-notrans case only.
    Comprehensive tuning is planned in future releases;
  • Fix magmablas_?gemm_vbatched routines to correctly handle batch sizes over 65535. The same fix is applied to vbatched syrk, herk, syr2k, her2k, symm, hemm, and trmm;
  • Fix a bug in the FP32 <-> FP16 conversion routines (magmablas_hlag2s and magmablas_slag2h). The bug used to cause a launch failure for very large matrices;
  • Fix a bug in batched LU factorization to avoind NaNs when singularity is ancountered;
  • Fix a bug in batched LU factorization to ensure that the first pivot is always returned even when multilpe pivots with the same absolute value are found;
  • Add Frobenius norm for general matrices
    (supported as option to magmablas_Xlange for X = 's', 'd', 'c', or 'z').

MAGMA MIC 1.4.0
2015-07-12

MAGMA MIC 1.4.0 is now available. This release provides implementations for MAGMA's one-sided (LU, QR, and Cholesky) and two-sided (Hessenberg, bi- and tridiagonal reductions) dense matrix factorizations, as well as linear and eigenproblem solver for Intel Xeon Phi Coprocessors. More information on the approach is given in this presentation.

clMAGMA 1.3
2014-11-14

clMAGMA is an OpenCL port of MAGMA. It supports 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 clMath Libraries (formerly APPML).

Included in the clMAGMA 1.3 release are routines for the following algorithms:

  • LU, QR, and Cholesky factorizations in both real and complex  arithmetic (single and double);
  • Linear and least squares solvers based on correspondingly the LU/Cholesky and QR factorizations in both real and complex  arithmetic (single and double);
  • Reductions to Hessenberg, bidiagonal, and tridiagonal forms using orthgonal similarity transformationsin both real and complex arithmetic (single and double);
  • Eigen and singular value problem solvers in both real and complex arithmetic (single and double);
  • Orthogonal transformation routines.
