MAGMA 2.5.0 RC1
2018-11-16

MAGMA 2.5.0 RC1 is now released. Updates include:

  • New routine: magmablas_Xgemm_batched_strided (X = {s, d, c, z}) is the stride-based variant of magmablas_Xgemm_batched;
  • New routine: magma_Xgetrf_native (X = {s, d, c, z}) performs the LU factorization with partial pivoting using the GPU only. It has the same interface as the hybrid (CPU+GPU) implementation provided by magma_Xgetrf_gpu. Testing the performance of this routine is possible through running testing_Xgetrf_gpu with the option (--version 3);
  • New routine: magma_Xpotrf_native (X = {s, d, c, z}) performs the Cholesky factorization using the GPU only. It has the same interface as the hybrid (CPU+GPU) implementation provided by magma_Xpotrf_gpu.
    Testing the performance of this routine is possible through running testing_Xpotrf_gpu with the option (--version 2)
  • Added benchmark for GEMM in FP16 arithmetic (HGEMM) as well as auxiliary functions to cast matrices from FP32 to FP16 storage (magmablas_slag2h) and from FP16 to FP32 (magmablas_hlag2s).

MAGMA 2.4.0
2018-06-25

MAGMA 2.4.0 is now released. Updates include:

  • Added constrained least squares routines (magma_[sdcz]gglse) and dependencies:
    magma_zggrqf - generalized RQ factorization
    magma_zunmrq - multiply by orthogonal Q as returned by zgerqf
  • Performance improvements across many batch routines, including batched TRSM, batched LU, batched LU-nopiv, and batched Cholesky
  • Fixed some compilation issues with inf, nan, and nullptr.

MAGMA-sparse

  • Changed the way how data from an external application is handled:
    There is now a clear distinction between memory allocated/used/freed from MAGMA and the user application. We added a functions magma_zvcopy and magma_zvpass that do not allocate memory, instead they copy values from/to application-allocated memory.
  • The examples ( in example/example_sparse.c ) give a demonstration on how these routines should be used.

MAGMA 2.3.0
2017-11-15

MAGMA 2.3.0 is now released. Updates include:

  • Moved MAGMA's repository to Bitbucket: https://bitbucket.org/icl/magma
  • Added support for Volta GPUs
  • Improved performance for batched LU and QR factorizations on small square sizes up to 32
  • Added test matrix generator to many testers
  • Launched Data Analytics tools (MagmaDNN 0.1 Alpha) using MAGMA as computational backend

MAGMA-sparse

  • Added support for CUDA 9.0
  • Improved the ParILUT algorithm w.r.t. stability and scalability
  • Added ParICT, a symmetry-exploiting version of the ParILUT algorithm

MAGMA 2.2 release
2016-11-20

MAGMA 2.2.0 is now released. Updates include:

  • Added variable size batched Cholesky factorization magma_[sdcz]potrf_vbatched
  • Added new fixed size batched BLAS routines {hemm, symm, hemv, symv, trmm}_batched
  • Added new variable size batched BLAS routines {hemm, symm, hemv, symv, trmm, trsm}_vbatched
  • Fixed memory leaks in {sy,he}evdx_2stage and getri_outofplace_batched.
  • Fixed bug for small matrices in {symm, hemm}_mgpu and updated tester.
  • Fixed libraries in make.inc examples for MKL with gcc.
  • More robust error checking for Batched BLAS routines.

MAGMA-sparse

  • Added Incomplete Sparse Approximate Inverse (ISAI) Preconditioner for sparse triangular solves, including batched generation.
  • Added Block-Jacobi triangular solves, including variable blocksize (based on supervariable amalgamation).
  • Added ParILUT, a parallel threshold ILU based on OpenMP.
  • Added CSR5 format and CSR5 SpMV kernel, a sparse matrix vector product often outperforming the cuSPARSE SpMV CSR and HYB.

MAGMA 2.1 release
2016-08-30

MAGMA 2.1 for CUDA is now available. New features and updates include:

  • Variable size batched routines (gemm, gemv, syrk, syr2k).
  • Improved SVD performance for tall (m >> n) or wide (m << n) matrices.
  • Preconditioned QMR.
  • Expanded doxygen documentation.
  • For MAGMA v1 compatability, initializes default queue for each GPU on first use, instead of in magma_init.

Please take this survey to help improve MAGMA, LAPACK, and other dense linear algebra libraries. We estimate that it should take 10 minutes to fill it out.  Thank you very much.
