Releases
v0.87.4
Minor changes since 0.87.0
Fixed UpdatedMappedDiagonal prototype in El/blas_like/level1/decl.hpp (to avoid undefined references)
Fixed call to 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 SparseMatrix
and DistSparseMatrix
in MATRIX_MARKET
format
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 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
Intel compilers before version 17 update 1 will not properly compile Elemental (see Issue #177 )
Compiling MPICH with Clang on recent versions of OS X can lead to segfaults in MPID_Request_create
within an MPI_Alltoallv
call (see Issue #200 )
