Elemental version 0.87.7 Latest
Latest

Minor changes since 0.87.0

  • Fixed a bug in the affine QP IPM initialization
  • Fixed a bug in the El::SparseInvCov lambda definition for El::HermitianFunction
  • Fixed a bug in the sparse Dantzig Selector implementation
  • Added operator* for integer index ranges
  • Fixed bit-rot in many python IPM example drivers
  • Fixed CMAKE_INSTALL_LIBDIR usage in ElVars.in
  • Fixed El::UpdatedMappedDiagonal prototype in El/blas_like/level1/decl.hpp (avoiding undefined ref's)
  • Fixed call to El::lin_solve::ScaLAPACKHelper in src/lapack_like/solve/Linear.cpp
  • Avoided python global variables (which were not propagating on recent versions of OS X)
  • Avoided compiler error from implicit conversions between El::Int and El::BigFloat for member variables
  • Simplified src/core/mpi_register.cpp and avoided unfreed MPI memory
  • Avoided unused variables
  • Added support for reading El::SparseMatrix and El::DistSparseMatrix in El::MATRIX_MARKET format
  • Fixed 64-bit integer builds
  • Fixed bug in promotion of El::Quad
  • Fixed a substantial amount of bit-rot in the Python interface and its examples
  • Fixed CTest on Mac OS X
  • Extended interface of El::LUMod to support any low-rank modification
  • Added missing implementation of sequential dense equilibration so that the sequential dense Interior Point Methods now function
  • Extended more routines from accepting El::ElementalMatrix to the more general El::AbstractDistMatrix
  • Renamed DEBUG_ONLY to EL_DEBUG_ONLY, RELEASE_ONLY to EL_RELEASE_ONLY, and DEBUG_CSE to EL_DEBUG_CSE and ensured that they function without a preceding import of the El namespace
  • Removed invalid calls to std::numeric_limits for non-STL datatypes
  • Greatly curated the example drivers (e.g., by always making explicit use of the El namespace)
  • Added (and incorporated) an El::MakeFunction helper for converting lambdas to an appropriate std::function

Notable functionality additions

  • (Arbitrary-precision) real and complex Lenstra/Lenstra/Lovasz (LLL) lattice reduction
  • (Arbitrary-precision) real and complex Block Korkine-Zolotarev (BKZ) and various enumeration heuristic extensions (BKZ 2.0 and y-sparse enumeration)
  • (Arbitrary-precision) distributed divide-and-conquer real symmetric tridiagonal EVD
  • (Arbitrary-precision) distributed divide-and-conquer bidiagonal SVD
  • (Arbitrary-precision) distributed Aggressive Early Deflation Hessenberg QR algorithms
  • (Arbitrary-precision) distributed high-performance level 3 BLAS complex triangular eigenvector computation
  • (Arbitrary-precision) distributed high-performance pseudospectra
  • (Arbitrary-precision) distributed real and complex sparse linear solvers (including a special interface for symmetric quasi-semidefinite matrices)
  • (Arbitrary-precision) distributed real and complex generalized sparse least squares solvers (including LSE and GLM)
  • (Arbitrary-precision) distributed dense and sparse Linear, Quadratic, and Second-Order Cone Programming

Packaging additions

Relevant toolchain bugs

  • GCC Release builds are (by default) blocked on OS X due to -O3 optimizations leading to a stack_not_16_byte_aligned_error error in the 5.x and 6.x series of GCC. Please see #181 for a more detailed discussion. The CMake flag -D EL_IGNORE_OSX_GCC_ALIGNMENT_PROBLEM=ON will prevent the error for OSX GCC Release builds. Further, Homebrew's GCC 4.9 does not properly handle exceptions (see Homebrew/homebrew-core#7837 (comment)).
  • OpenMPI versions before 1.8.1 are prevented by the CMake configuration due to bugs in OpenMPI 1.6.5's handling of complex datatypes
  • Intel compilers before version 17 update 1 will not properly compile Elemental (see Issue #177 )
  • Compiling MPICH 3.2 with Clang on recent versions of OS X can lead to segfaults in MPID_Request_create within an MPI_Alltoallv call (see Issue #200 )
  • MPICH must be configured with the --enable-two-level-namespace option on Mac OS X (see Issue #203 )

Packaging additions

Relevant toolchain bugs

  • GCC Release builds are (by default) blocked on OSX due to -O3 optimizations leading to a stack_not_16_byte_aligned_error error. Please see #181 for a more detailed discussion. The CMake flag -D EL_IGNORE_OSX_GCC_ALIGNMENT_PROBLEM=ON will prevent the error for OSX GCC Release builds.
  • OpenMPI versions before 1.8.1 are prevented by the CMake configuration due to bugs in OpenMPI 1.6.5's handling of complex datatypes

Version 0.85

Elemental 0.85

The official release for version 0.85 of Elemental is now available:
libelemental.org/pub/releases/Elemental-0.85.tgz

Added functionality

  • Sparse-direct Cholesky and Bunch-Kaufman due to merging Clique into Elemental
  • Sparse-direct least squares, ridge regression, and Tikhonov regularization
  • Sparse Herk and various other BLAS1-like routines
  • A (nearly full) manually-constructed C interface
  • A (nearly full) manually-constructed Python interface, including extensions of Display functionality to matplotlib (for matrices) and networkx (for graphs)
  • Support for Read, Write, and ReadWrite matrix proxies so that routines implemented for specific datatypes and/or data distributions can be extended to more general datatypes and arbitrary distribution choices
  • Essentially all distributed routines in the library were generalized to AbstractDistMatrix for convenience (using proxies)
  • Single-precision Hermitian eigensolvers are now supported (via proxies which convert to double-precision for PMRRR)
  • Added Three-valued and Bernoulli, GEPPGrowth and Druinsky-Toledo, Fourier-Identity ("spikes and sines") and Walsh-Identity ("spikes and Hadamard") matrices
  • Added ability to compute coherence
  • Added ability to use operator() to extract contiguous submatrices (and converted library)
  • Extended control of SVD and LDL via new SVDCtrl and LDLCtrl structures
  • Improved performance of IO routines when ColStride() and/or RowStride() are 1

Bug fixes

  • Fixed a variety of compilation errors which did not appear with g++
  • Fixed an (uncommon) bug in distributed HermitianFrobeniusNorm
  • Added missing shrink of the phase vector in qr::BusingerGolub
  • Added missing scalar argument to Matrix::UpdateDiagonal
  • Fixed Ehrenfest matrix generation
  • Fixed indexing of Householder phases in sequential Bidiag
  • Fixed offset used by rq::ExplicitTriang
  • Fixed BlockDistMatrix version of MATRIX_MARKET Read
  • Fixed BLAS wrappers for complex herk, her2k, her, and her2
  • Fixed PURE/HYBRID CMake detection (thanks to Richard Boyd)

Refactoring

  • Removed MakeTriangular (due to the more general MakeTrapezoidal)
  • Replaced AxpyTriangle with AxpyTrapezoid
  • Added a control structure for Bisect
  • Significantly refactored/simplified Trr2k
  • Removed spurious integer argument to TriW
  • Removed Riemann matrix due to vague definition (and overlap with Redheffer)
  • Removed hyphens in directory names to avoid python conflict

Name changes

  • Renamed namespace "elem" to "El", and "elem.hpp" to "El.hpp"
  • Moved auxiliary PMRRR headers into pmrrr/ subfolder
  • "Pseudospectra" -> {"SpectralPortrait","SpectralWindow","SpectralCloud"}
  • Better organization/naming for explicit QR/RQ/LQ factorizations

Thanks

  • Richard Boyd (of GTRI) for reporting the PURE/HYBRID configuration detection problem
  • Field van Zee (of UT Austin) for clarifying the {c,z}her2 and {c,z}her2k scalar argument conventions
  • Rodrigo Canales for noticing and fixing several missing static instantiations
  • Yingzhou (Ryan) Li for reporting the vecLib/Accelerate issue

Documentation:
[HTML] http://libelemental.org/documentation/0.84/
[PDF] http://libelemental.org/documentation/elem-0.84.pdf

The significant changes since release 0.83 are listed below (and a number of bugs in the release candidate for 0.84 were fixed).

New Functionality

Fundamental additions

  • Low-rank Cholesky up-/down-dating (CholMod)
  • Rank-one updates to LU factorizations (LUMod)
  • Added Generalized RQ and QR factorizations and associated General Linear Model (GLM) and Equality-constrained Least Squares (LSE) solvers
  • Pseudospectral computations can now be driven by various kernels, including
    multi-shift Hessenberg/(quasi-)triangular solves. There is also now support a
    variety of configurations for outputting snapshots of the results
  • Multi-shift Hessenberg solves (MultiShiftHessSolve)
  • Multi-shift quasi-triangular solves (MultiShiftQuasiTrsm)
  • Quasi-triangular solves (QuasiTrsv/QuasiTrsm)
  • Hyperbolic Householder transforms
  • Basic support for a block version of DistMatrix (BlockDistMatrix)
  • Support for parallel Schur decompositions via ScaLAPACK's Hessenberg QR algs.
  • Support for redistributing between DistMatrix and BlockDistMatrix [MC,MR] dists.
  • All user-level routines now use permutation vectors instead of pivot vectors
  • Alternating Direction Method of Multipliers (ADMM) implementations of Basis Pursuit, Linear and Quadratic Programs, and Sparse Inverse Covariance Selection

Minor/incremental improvements

  • Added {lq,rq,qr}::SolveAfter
  • Added SymmetricSolve and HermitianSolve
  • Support for converting real (quasi-triangular) Schur forms to complex
    (triangular) form
  • Support for computing the eigenvalues of quasi-triangular matrices
  • LQ/QR/RQ factorizations now force positive (or zero) diagonal entries in the
    resulting triangular matrix
  • Grid now supports both row-major and column-major orderings
  • Support for diagonal scalings of trapezoidal matrices (DiagonalScaleTrapezoid)
  • Added Global{Col,Row} and Local{Col,Row}Offset member functions to DistMatrix
  • Norm and Max now support more data distributions
  • Min and Max implementations (which do not use the absolute values)
  • Added Bull's Head, Hatano-Nelson, random Helmholtz Green's, Trefethen,
    Triangle, and Whale matrices.

Instrumentation/visualization/testing

  • More file formats for Read and Write (e.g., ASCII and MATRIX_MARKET)
  • Display windows are now strictly sized according to the size of the matrix

Maintenance

Library bugfixes

  • Fixed several small memory leaks in Grid
  • AbstractDistMatrix::Empty() now recomputes shifts to ensure the matrix is kept
    in a legal state
  • Moves of non-views to views are now converted to copies
  • Fixed deflation bug in PMRRR when no eigenvectors are requested
  • Fixed bugs in ApplyPackedReflectors, QuasiDiagonalScale, TriangularInverse, Trr, and Trsv

Maintenance/syntax

  • Algorithmic options are now handled via control structures with default
    constructors
  • Preprocessor definitions and macros now namespaced with "ELEM"
  • Grid argument to DistMatrix::[Locked]Attach was moved before the dependent
    alignment arguments
  • Added a 'Mod' routine which supports modular arithmetic with negative integers
  • Copy assignments now return non-const references
  • Move constructors are now "noexcept"
  • Checks were added to ensure DistMatrix views are not improperly aligned
  • PMRRR (and therefore Elemental) no longer requires a Fortran compiler to build
  • Renamed "ShiftedTrsm" to "MultiShiftTrsm" and placed in BLAS3
  • Renamed "Min" and "Max" to "MinAbs" and "MaxAbs"
  • Renamed "Inertia" to "InertiaType" and "HermitianInertia" to "Inertia"
  • The unnecessary Orientation arguments were removed from QuasiDiagonal{Scale,Solve}
  • All interfaces now assume the usage of 'left' diagonals, which use an offset relative to the diagonal which contains the upper-left entry

Documentation

  • Documentation for BlockDistMatrix is currently missing

Build system

  • Several bugs fixed in detection of support for C++11 random number generation
  • Configuration tests moved into separate files

Python interface

  • The python interface was removed due to SWIG's lack of C++11 support,
    the lack of a maintainer for the interface, and the fact that a manual
    C interface is planned.

Thanks

  • Jed Brown for suggesting the preprocessor namespacing
  • Drew Lewis for reporting the TriangularInverse bug
