LAPACK is really a software package given by Univ. of Tennessee; Univ. of California, Berkeley; Univ. of Colorado Denver; and NAG Ltd.
LAPACK is designed in Fortran 90 and offers 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 will also be provided, similar to related computations including reordering with the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, however, not general sparse matrices. In all areas, similar functionality is provided the real deal and complex matrices, in single and double precision.
The original goal in the LAPACK project would have been to make the popular EISPACK and LINPACK libraries run efficiently on shared-memory vector and parallel processors. On treadmills, LINPACK and EISPACK are inefficient since their memory access patterns forget the multi-layered memory hierarchies on the machines, thereby spending a lot of time moving data as an alternative to doing useful floating-point operations. LAPACK addresses this issue by reorganizing the algorithms to make use of block matrix operations, including matrix multiplication, from the innermost loops. These block operations may be optimized for every architecture to be the cause of the memory hierarchy, therefore provide a transportable method to achieve best quality on diverse modern machines. We make use of the term transportable as opposed to portable because, for fastest possible performance, LAPACK necessitates that highly optimized block matrix operations be already implemented on each machine.
LAPACK routines are written in addition to being much as possible in the computation is carried out by calls for the Basic Linear Algebra Subprograms BLAS. LAPACK was made at the outset to take advantage of the Level 3 BLAS a few specifications for Fortran subprograms which do various types of matrix multiplication as well as the solution of triangular systems with multiple right-hand sides. Because with the coarse granularity on the Level 3 BLAS operations, their use promotes best quality on many high-performance computers, especially if specially coded implementations are offered by the manufacturer.
Highly efficient machine-specific implementations in the BLAS are for sale to many modern high-performance computers. For information known vendor- or ISV-provided BLAS, consult the BLAS FAQ. Alternatively, an individual can download ATLAS to automatically generate an optimized BLAS library for that architecture. A Fortran 77 reference implementation with the BLAS is obtainable from netlib; however, its use is discouraged mainly because it will not perform as well like a specifically tuned implementation.

Information: Those libraries were created with CMAKE for Visual Studio 2010 and INTEL compilers and correspond to LAPACK 3.5.0.
Thanks to Olumide, Evgenii Rudnyi and Mark Hoemmen at /group/matrixprogramming their early suggestions and also the reading the draft of the HOWTO. Any inaccuracies on this document are mine. Use properly. LAPACK was created as a couple-tiered Fortran library, comprising advanced level subroutines and lower-level Basic Linear Algebra Subprograms BLAS so that you can effectively exploit the caches on modern cache-based architectures /wiki/LAPACK. For reference purposes, the LAPACK installation offers untuned version in the BLAS which just isn't optimized for virtually any architecture. This reference BLAS implementation can be orders of magnitude slower than optimized implementations, for matrix factorizations and also other computationally intensive matrix operations. Optimized implementations the BLAS are offered by a quantity of vendors and projects including: Intel commercial, AMD, ATLAS, and GotoBLAS.
The Reference BLAS for Windows could be downloaded here. MKL - /en-us/intel-mkl/This is really a good match to select INTEL Fortran compiler obviously. ATLAS is try and, by self-discovery, automatically generate an optimized BLAS library. For a detail by detail procedure please refer for the ALTAS Forum
The GotoBLAS source is obtainable from here theres short registration form to fill, and might be compiled for Windows with MinGW. No changes need to be created to GotoBLAS config file, unless a specific compiler is preferred. Happily, the config file automatically enables multithreading if many processor can be acquired.
Download and extract the GotoBLAS source to your directory usually chosen, and earn any desired changes towards the config file the default option should likewise work well.
cd towards the top-level directory containing the origin, and type make
a, as well as a symbolic link libgoto.a pointing to the file. For example, libgotobanias-r1.26.a but also the Windows library and dll are generated automagically.
Windows should be told where to get this dll, else you is certain to get a serious error once you try running your program. There are several strategies to do do this. One, is usually to add the location from the dll for the PATH environment variable. Another is always to simply copy the dll to your Windowssystem32 folder. I did the later.
For more info, make reference to Microsoft guidelines on Search Path Used by Windows to Locate a DLL
Download the LAPACK precompiled binaries. File names in the precomputed debug libraries end with all the letter d plus in comparison towards the release versions and.
Locate your BLAS libraries on your machine. You may want to select the Debug config if you choose GOTOBLAS
Move or Copy the libraries from step 1 inside the LAPACK - VS-Example folder.
If that you are not utilizing the Reference BLAS, you simply must modify alter the properties Linker General Additional Library Directory to share with Visual Studio the spot that the libraries are, plus add the category of your BLAS library in Linker Input Additional Dependencies
Compile the project and run the resulting executable. You should find the output:
Hello World INFO 0 3.00000000000000 0.333333333333333 4.00000000000000 0.666666666666667 - 4.00000000000000 4.50000000000000 END OF
Download the LAPACK precompiled binaries for MinGW. You should have a 2 files: in case you also want the Reference BLAS.
OPTIONAL: Obtain a tuned version of BLAS for ones machine talk about Compiling GotoBLAS.
For C program, rename the prototypes from the above program to
Add the the BLAS and LAPACK libraries for the Visual Studio project settings,
under Linker - General - Additional Library Directories: your directory where your is.
under Linker - Input - Additional Dependencies: For example, in this little machine, I am with all the Reference BLAS
Note: because BLAS libraries commonly provide faster versions of some LAPACK subroutines, the BLAS library need to be listed before before LAPACK library.
Note: ensure that all the dll BLAS, LAPACK, MinGW dlls are in your system path or copy them from the WINDOWSsystem32 folder, else binary wont run.
Compile the project and run the resulting executable. You should obtain the output: The solution is
Part 3 in this HOWTO will briefly explain what dgesv means approaches to call it and also other LAPACK subroutines with all the appropriate arguments.
In the last section, I explained the best way to call a LAPACK subroutine dgesv from your C or C program, but I wouldn't explain the dgesv meant together with its arguments. This may be the purpose on this part on the HOWTO. In doing so, I will refer to your LAPACK documentation and hopefully show how easy it really is to find a proper LAPACK subroutine and produce the corresponding C/C function prototype for doing this.
From the LAPACK naming scheme - -, it truly is plain to determine that:
This refers for the type of driver routine solver in lay talk with be familiar with solve the linear system. There are two kinds on drivers: simple drivers suffixed with sv and expert drivers suffixed with svx. Refer to.
Therefore dgesv is not difficult driver routine to get a general/unymmetric matrix containing double precision data.
From the page /lapack/double/dgesv.f, we could see that the subroutine dgesv has 8 arguments.
The first argument is N, an integer. This is marked as a possible input meaning argument will never be modified, in contrast to an input argument or perhaps input/output argument inside the documentation. In C/C speak we could therefore make reference to argument 1 as being a constant integer const int. However, because in Fortran all ALL arguments, without exception are passed by address, the style of N in C/C is: const int. Same applies to argument 2.
Argument 3, marked from the documentation just as one input/output double precision array. In C/C terms input/output means NOT-constant. Therefore, because arguments are passed by reference, the form of argument 3 is: double.
Argument 5, marked within the documentation just as one output integer array. In C/C terms what this means is the argument isn't a const. Therefore argument 5 is of type int. Same applies argument 8, although argument isn't an array remember, all Fortran arguments are passed by address.
It should be clear why the C/C prototype for dgesv is CODE: SELECT ALL extern C void dgesv const int, const int, double, const int, int, double, const int, int ;
A pattern for implementing directly LAPACK subroutines should be clear.
First find the proper subroutine from the listing of available drivers here.
Create a the correct C/C prototype for that driver.

Your post for the forum will likely be appreciated. LAPACK 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 may also be provided, just like related computations like reordering on the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, yet not general sparse matrices. In all areas, similar functionality is provided the real deal and complex matrices, in the single and double precision.
Release 3.0 of LAPACK introduces new routines, along with extending the functionality of existing routines. For detailed information about the revisions, please refer towards the LAPACK revisions info
LAPACK can be an open source and portable command-line software that can offer linear algebra library coded in Fortran77 and designed to supply various routines for solving least-squares solutions of linear systems of equations, systems of simultaneous linear equations, singular value problems, and eigenvalue problems.
These routines are developed in such a way which they allow the computation to execute as calls to BLAS Basic Linear Algebra Subprograms.
The main goal in the LAPACK library is to make LINPACK and EISPACK libraries run efficiently on parallel and shared-memory vector processors. A Fortran95 interface with the LAPACK library also exists, as well being a C version for just a subset of LAPACK routines, plus a f2c ed version.
This version adds xGEQRT, a QR factorization facility so that better performance if the blocked reflectors ought to be reused.
It adds xGEQRT3, a recursive QR factorization facility that has top rated on tall and skinny matrices.
It adds xTPQRT, an accumulation of Communication-Avoiding QR sequential kernels.
It replaces the build system with CMAKE for better portability.

If you download the application, it truly is critically important that you just check the ATLAS errata file. This file lists all known errors in ATLAS, and many types of known system problems eg., compiler errors, etc, and then fixes and workarounds.
The University Wikis login page will quickly be while using the same UT Login page with which you're already familiar from logging into other services on campus.
Notes about BLAS, LAPACK, and ATLAS before I forget again. The reference for these particular is
BLAS could be the Basic Linear Algebra Subprograms. It is really a set of routines used to carry out common low level matrix manipulations including rotations, or dot products. BLAS needs to be optimized to perform on given hardware. This could be done by letting a vendor supplied package ie, supplied by Sun, or Intel, in any other case by with all the ATLAS software.
LAPACK may be the Linear Algebra Package. It extends BLAS to deliver higher level linear algebra routines for instance computing eigenvalues, or picking out the solutions with a system of linear equations.
ATLAS could be the Automatically Tuned Linear Algebra Software package. It is software that efforts to tune the BLAS implementation it provides for a hardware. ATLAS also offers a very minimal LAPACK implementation, so it ought to be compiled through instructions on its sourceforge page. This allows it to adopt an existing LAPACK installation, and modify it to make use of ATLAS provided BLAS, and LAPACK routines.
Download ATLAS. Install in src/ATLAS, and unzip.
cd BLD, and run configure. I added the options
this says to switch all compilers to build position independent code eg, for shared libs
which tells ATLAS to tune to get a 2.2 Mhz Pentium chip.
once the configure step is conducted, then look in, and find the F77 and F77FLAGS values
go towards the LAPACK source, and cp or even in new versions to
Modify these 4 values as shown substituting your own personal values for FORTRAN, OPTS, and NOOPT. Notice that NOOPT may be the same is OPT that the optimization switch - O removed.
I did get errors as the second tests finish in 0 seconds, but googling some sites says that is okay.
install lib by making/share/apps/lapack - 3.2.1/lib and putting lapack LINUX.a there.
go back in src/ATLAS. Remove the bld directory, and re-create it. Run the configure step again, but add - -with-netlib- lapack/share/apps/lapack - 3.2.1/lib/lapack LINUX.a being a config option
cp /share/apps/libatlas-3.8.3/lib
chmod 444/share/apps/libatlas-3.8.3/lib
