LAPACK 3.5.0 Software Library For Numerical Linear Al...

LAPACK by LAPACK Dev Team is written in Fortran 90 and provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems. The associated matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are also provided, as are related computations such as reordering of the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, but not general sparse matrices. In all areas, similar functionality is provided for real and complex matrices, in both single and double precision.

The original goal of the LAPACK 3.5.0 project was to make the widely used EISPACK and LINPACK libraries run efficiently on shared-memory vector and parallel processors. On these machines, LINPACK and EISPACK are inefficient because their memory access patterns disregard the multi-layered memory hierarchies of the machines, thereby spending too much time moving data instead of doing useful floating-point operations. LAPACK [lapack3.5.0.exe] addresses this problem by reorganizing the algorithms to use block matrix operations, such as matrix multiplication, in the innermost loops. These block operations can be optimized for each architecture to account for the memory hierarchy, and so provide a transportable way to achieve high efficiency on diverse modern machines. We use the term " transportable" instead of " portable" because, for fastest possible performance, LAPACK - 5.8MB requires that highly optimized block matrix operations be already implemented on each machine.

LAPACK 3.5.0 routines are written so that as much as possible of the computation is performed by calls to the Basic Linear Algebra Subprograms (BLAS). LAPACK is designed at the outset to exploit the Level 3 BLAS  —   a set of specifications for Fortran subprograms that do various types of matrix multiplication and the solution of triangular systems with multiple right-hand sides. Because of the coarse granularity of the Level 3 BLAS operations, their use promotes high efficiency on many high-performance computers, particularly if specially coded implementations are provided by the manufacturer.

Highly efficient machine-specific implementations of the BLAS are available for many modern high-performance computers. For details of known vendor- or ISV-provided BLAS, consult the BLAS FAQ. Alternatively, the user can download ATLAS to automatically generate an optimized BLAS library for the architecture. A Fortran 77 reference implementation of the BLAS is available from netlib; however, its use is discouraged as it will not perform as well as a specifically tuned implementation.

What is new in official LAPACK 3.5.0 software version? - Unable to resolve 3.5.0 news. What is expected in the future? Newly-made LAPACK 3.6 be downloaded from current page, we also looking forward to unconfirmed 3.7 release build. You may download lapack-3.5.0.tgz directly, estimated download time by ADSL or EDGE [~1.8 Mbit/s] is 0:00:26. Just write the reviews of the LAPACK. System requirements are unspecified. Program has been scanned and verified by the several antivirus and anti-spyware applications and LAPACK found to be clean. No guide or LAPACK tutorial available. The following languages are supported by LAPACK: English.
