PRIMME 3.2

Changes in PRIMME 3.2:

• Fixed Intel 2021 compiler error "Unsupported combination of types for <tgmath.h>."
• Fixed compiling issues with PGI compiler also about tgmath.h.
• Fixed dprimme() and other variants not returning error code PRIMME_MAIN_ITER_FAILURE when it should do in some corner cases.
• Fixed warnings from gcc/clang undefined behavior sanitizers.
• Matlab: renamed disp to reportLevel.
• Matlab: add flag returnUnconverged to return unconverged pairs.
• Matlab: return primme_params/primme_svds_params.

PRIMME 3.1.1

Changes in PRIMME 3.1.1:

• Fixed version in the shared library name.

• Fixed compilation errors with pgcc.

PRIMME 3.1

Changes in PRIMME 3.1 (released on May 2, 2020):

• Fixed compilation issues in F90 interface and examples.

• Fixed bug in block orthogonalization.

• Updated Python interface to Python version 3.8.

PRIMME 3.0.2

Changes in PRIMME 3.0.2:

• Fixed dynamic library name in MacOS.

PRIMME 3.0.1

Changes in PRIMME 3.0.1:

• Remove // comment in include/primme_eigs.h

PRIMME 3.0

Changes in PRIMME 3.0:

• Added support for the generalized Hermitian eigenvalue problem and the standard normal eigenvalue problem.

• Added support for GPU.

• Added support for half precision.

• Added block orthogonalization.

• Resolution of all linear system of equations simultaneously in Jacobi-Davidson.

• Added interface for Fortran 90.

• Added an optional callback for broadcasting.

• The callbacks can work with different precision than the main call (see for instance "matrixMatvec_type" and "globalSumReal_type").

• Added new counters: "numGlobalSum", "volumeGlobalSum", "numBroadcast", "volumeGlobalSum", "timeOrtho", "timeGlobalSum", "timeBroadcast".

• Added "primme_params_create()", "primme_params_destroy()", "primme_svds_params_create()", and "primme_svds_params_destroy()".

PRIMME 2.2

Changes in PRIMME 2.2:

• Improved stability for single precision.

• Improved support for the shared library.

• Updated PETSc examples in Fortran; added new examples in single
  precision.

• Improved support for FreeBSD and MacOS.

• New install and uninstall actions.

• MATLAB interface support for user-defined stopping criterion (see
  "convTestFun") and stopping with ctr+c.

• Optional suffix on BLAS/LAPACK function names (for OpenBLAS, see
  PRIMME_BLAS_SUFFIX).

• Replaced XHEGV by XHEGVX (to support ESSL).

• Fixed bugs in the library and in the Matlab interface.

PRIMME 2.1

Changes in PRIMME 2.1:

• Improved robustness by broadcasting the result of critical LAPACK
  operations instead of replicating them on every process; this is
  useful when using a threaded BLAS/LAPACK or when some parallel
  processes may run on different architectures or libraries.

• New stopping criteria in QMR that improve performance for interior
  problems.

• MATLAB interface reimplementation with support for singular value
  problems, "primme_svds()", with double and single precision, and
  compatible with Octave.

• R interface

• Proper reporting of convergence history for singular value
  solvers.

PRIMME 2.0

Changes in PRIMME 2.0:

• Changed license to BSD 3-clause.
• New support for singular value problems.
• New support for float and complex float arithmetic.
• Support for problem dimensions larger than 2^31, without requiring BLAS and LAPACK compiled with 64-bits integers.
• Improve robustness and performance for interior problems; implemented advanced refined and harmonic-Ritz extractions.
• Python interface compatible with NumPy and SciPy Library.
• Optional user-defined convergence function, convTestFun.

PRIMME 1.2.2

Changes in PRIMME 1.2.2:

• Fixed wrong symbols in libdprimme.a and libzprimme.a.
• primme_set_method sets JDQMR instead of JDQMR_ETol for preset methods
  DEFAULT_MIN_TIME and DYNAMIC when seeking interior values.
• Fixed compilation of driver with a PETSc installation without HYPRE.
• Included the content of the environment variable INCLUDE for compiling the driver.
