Bisection relies on the Sturm count: for a given shift $ \sigma $, the number of negative pivots in the factorization {$ T \sigma I = L D L^T $} equals the number of eigenvalues of {$T$} that are smaller than $ \sigma $. In IEEE-754 arithmetic, the value $ \infty $ permits the computation to continue past a zero pivot, producing a correct Sturm count when {$T$} is unreduced. Demmel and Li showed in the 90s that using $ \infty $ rather than testing for zero pivots within the loop could improve performance significantly on certain architectures. When eigenvalues are to be computed to high relative accuracy, it is often preferable to work with {$ L D L^T $} factorizations instead of the original tridiagonal {$T$}, see for example the MRRR algorithm. In these cases, the Sturm count has to be computed from {$ L D L^T $} . The differential stationary and progressive qds algorithms are the methods of choice. While it seems trivial to replace {$T$} by {$ L D L^T $}, in reality these algorithms are more complicated: in IEEE-754 arithmetic, a zero pivot produces an overflow, followed by an invalid exception (NaN), that renders the Sturm count incorrect. We present alternative, safe formulations that are guaranteed to produce the correct result. Benchmarking these algorithms on a variety of platforms shows that the original formulation without tests is always faster provided no exception occurs. The transforms see speed-ups of up to $ 2.6 \times $ over the careful formulations. Tests on industrial matrices show that encountering exceptions in practice is rare. This leads to the following design: First, compute the Sturm count by the fast but unsafe algorithm. Then, if an exception occurred, recompute the count by a safe, slower alternative. The new Sturm count algorithms improve the speed of bisection by up to $ 2 \times $ on our test matrices.

The standard two dimensional arrays of Fortran and C (also known as full format) that are used to represent triangular and symmetric matrices waste nearly half of the storage space but provide high performance via the use of Level 3 BLAS. Standard packed format arrays fully utilize storage (array space) but provide low performance as there is no Level 3 packed BLAS. We combine the good features of packed and full storage using RFPF to obtain high performance via using Level 3 BLAS as RFPF is a standard full format representation. Also, RFPF requires exactly the same minimal storage as packed format. Each LAPACK full and/or packed triangular, symmetric, and Hermitian routine becomes a single new RFPF routine based on eight possible data layouts of RFPF. This new RFPF routine usually consists of two calls to the corresponding LAPACK full format routine and two calls to Level 3 BLAS routines. This means no new software is required.

Numerous numerical experiments confirm the superior performance of our parallel QR algorithm in comparison with the existing ScaLAPACK code, leading to an implementation that is one to two orders of magnitude faster for sufficiently large problems, including a number of examples from applications.", acknowledgement = ack-nhfb, keywords = "aggressive early deflation; bulge chasing; Eigenvalue problem; hybrid distributed memory systems.; level 3 performance; multishift; nonsymmetric QR algorithm; parallel algorithms; parallel computations", note = "UMINF-09.06", } @TechReport{Agullo:2009:CSO, author = "Emmanuel Agullo and Bilel Hadri and Hatem Ltaief and Jack Dongarra", title = "Comparative Study of One-Sided Factorizations with Multiple Software Packages on Multi-Core Hardware", type = "LAPACK Working Note", number = "217", institution = inst-UTK-CS, address = inst-UTK-CS:adr, day = "28", month = apr, year = "2009", bibdate = "Wed Aug 24 12:36:41 MDT 2011", bibsource = "http://www.math.utah.edu/pub/tex/bib/lawn.bib", note = "UT-CS-09-640.", URL = "http://www.netlib.org/lapack/lawnspdf/lawn217.pdf", acknowledgement = ack-nhfb, } @TechReport{Ballard:2009:MCL, author = "Grey Ballard and James Demmel and Olga Holtz and Oded Schwartz", title = "Minimizing Communication in Linear Algebra", type = "LAPACK Working Note", number = "218", institution = inst-UCB-EECS, address = inst-UCB-EECS:adr, day = "15", month = may, year = "2009", bibdate = "Wed Aug 24 12:36:41 MDT 2011", bibsource = "http://www.math.utah.edu/pub/tex/bib/lawn.bib", note = "UCB/EECS-2009-62", URL = "http://www.netlib.org/lapack/lawnspdf/lawn218.pdf", acknowledgement = ack-nhfb, } @TechReport{Tomov:2009:ARU, author = "Stanimire Tomov and Jack Dongarra", title = "Accelerating the reduction to upper {Hessenberg} form through hybrid {GPU}-based computing", type = "LAPACK Working Note", number = "219", institution = inst-UTK-CS, address = inst-UTK-CS:adr, day = "24", month = may, year = "2009", bibdate = "Wed Aug 24 12:36:41 MDT 2011", bibsource = "http://www.math.utah.edu/pub/tex/bib/lawn.bib", note = "UT-CS-09-642.", URL = "http://www.netlib.org/lapack/lawnspdf/lawn219.pdf", acknowledgement = ack-nhfb, } @TechReport{Kurzak:2009:FDS, author = "Jakub Kurzak and Jack Dongarra", title = "Fully Dynamic Scheduler for Numerical Computing on Multicore Processors", type = "LAPACK Working Note", number = "220", institution = inst-UTK-CS, address = inst-UTK-CS:adr, day = "4", month = jun, year = "2009", bibdate = "Wed Aug 24 12:36:41 MDT 2011", bibsource = "http://www.math.utah.edu/pub/tex/bib/lawn.bib", note = "UT-CS-09-643.", URL = "http://www.netlib.org/lapack/lawnspdf/lawn220.pdf", acknowledgement = ack-nhfb, } @TechReport{Song:2009:DTS, author = "Fengguang Song and Asim YarKhan and Jack Dongarra", title = "Dynamic Task Scheduling for Linear Algebra Algorithms on Distributed-Memory Multicore Systems", type = "LAPACK Working Note", number = "221", institution = inst-UTK-CS, address = inst-UTK-CS:adr, day = "13", month = apr, year = "2009", bibdate = "Wed Aug 24 12:36:41 MDT 2011", bibsource = "http://www.math.utah.edu/pub/tex/bib/lawn.bib", note = "UT-CS-09-638.", URL = "http://www.netlib.org/lapack/lawnspdf/lawn221.pdf", acknowledgement = ack-nhfb, } @TechReport{Hadri:2009:EPT, author = "Bilel Hadri and Hatem Ltaief and Emmanuel Agullo and Jack Dongarra", title = "Enhancing Parallelism of Tile {$ Q R $} Factorization for Multicore Architectures", type = "LAPACK Working Note", number = "222", institution = inst-UTK-CS, address = inst-UTK-CS:adr, day = "4", month = sep, year = "2009", bibdate = "Wed Aug 24 12:36:41 MDT 2011", bibsource = "http://www.math.utah.edu/pub/tex/bib/lawn.bib", note = "UT-CS-09-645.", URL = "http://www.netlib.org/lapack/lawnspdf/lawn222.pdf", acknowledgement = ack-nhfb, } @TechReport{Ltaief:2009:SHP, author = "Hatem Ltaief and Stanimire Tomov and Rajib Nath and Peng Du and Jack Dongarra", title = "A Scalable High Performant {Cholesky} Factorization for Multicore with {GPU} Accelerators", type = "LAPACK Working Note", number = "223", institution = inst-UTK-CS, address = inst-UTK-CS:adr, day = "25", month = nov, year = "2009", bibdate = "Wed Aug 24 12:36:41 MDT 2011", bibsource = "http://www.math.utah.edu/pub/tex/bib/lawn.bib", note = "UT-CS-09-646.", URL = "http://www.netlib.org/lapack/lawnspdf/lawn223.pdf", acknowledgement = ack-nhfb, } @TechReport{Agullo:2010:QFT, author = "Emmanuel Agullo and Camille Coti and Jack Dongarra and Thomas Herault and Julien Langou", title = "{$ Q R $} Factorization of Tall and Skinny Matrices in a Grid Computing Environment", type = "LAPACK Working Note", number = "224", institution = inst-UTK-CS, address = inst-UTK-CS:adr, day = "6", month = apr, year = "2010", bibdate = "Wed Aug 24 12:36:41 MDT 2011", bibsource = "http://www.math.utah.edu/pub/tex/bib/lawn.bib", note = "UT-CS-10-651.

Since their basic unit of data is a submatrix rather than a scalar, they have a higher level of granularity than point algorithms, and this makes them well suited to high-performance computers. The numerical stability of the block algorithms in the new linear algebra program library LAPACK is investigated here. It is shown that these algorithms have backward error analyses in which the backward error bounds are commensurate with the error bounds for the underlying level-3 BLAS (BLAS3). One implication is that the block algorithms are as stable as the corresponding point algorithms when conventional BLAS3 are used. A second implication is that the use of BLAS3 based on fast matrix multiplication techniques affects the stability only insofar as it increases the constant terms in the normwise backward error bounds. For linear equation solvers employing {\em LU} factorization, it is shown that fixed precision iterative refinement helps to mitigate the effect of the larger error constants. Despite the positive results presented here, not all plausible block algorithms are stable; we illustrate this with the example of {\em LU} factorization with block triangular factors and describe how to check a block algorithm for stability without doing a full error analysis.", acknowledgement = ack-nhfb, keywords = "algorithms; performance", subject = "{\bf G.1.3}: Mathematics of Computing, NUMERICAL ANALYSIS, Numerical Linear Algebra. {\bf F.2.1}: Theory of Computation, ANALYSIS OF ALGORITHMS AND PROBLEM COMPLEXITY, Numerical Algorithms and Problems, Computations on matrices.", } @InProceedings{Dongarra:1992:LASb, author = "J.

Due to the complex hardware organization of advanced computer architectures the development of optimal level 3 BLAS code is costly and time consuming. However, it is possible to develop a portable and high-performance level 3 BLAS library mainly relying on a highly optimized GEMM, the routine for the general matrix multiply and add operation. With suitable partitioning, all the other level 3 BLAS can be defined in terms of GEMM and a small amount of level 1 and level 2 computations. Our contribution is twofold. First, the model implementations in Fortran 77 of the GEMM-based level 3 BLAS are structured to reduced effectively data traffic in a memory hierarchy. Second, the GEMM-based level 3 BLAS performance evaluation benchmark is a tool for evaluating and comparing different implementations of the level 3 BLAS with the GEMM-based model implementations.", acknowledgement = ack-nhfb, keywords = "algorithms; measurement; performance", subject = "{\bf G.1.3} Mathematics of Computing, NUMERICAL ANALYSIS, Numerical Linear Algebra, Linear systems (direct and iterative methods). {\bf D.3.2} Software, PROGRAMMING LANGUAGES, Language Classifications, FORTRAN 77. {\bf F.2.1} Theory of Computation, ANALYSIS OF ALGORITHMS AND PROBLEM COMPLEXITY, Numerical Algorithms and Problems, Computations on matrices. {\bf G.4} Mathematics of Computing, MATHEMATICAL SOFTWARE, Certification and testing. {\bf G.4} Mathematics of Computing, MATHEMATICAL SOFTWARE, Efficiency. {\bf G.4} Mathematics of Computing, MATHEMATICAL SOFTWARE, Portability**. {\bf G.4} Mathematics of Computing, MATHEMATICAL SOFTWARE, Reliability and robustness. {\bf G.4} Mathematics of Computing, MATHEMATICAL SOFTWARE, Verification**.", } @Article{Li:1998:RPT, author = "Ren-Cang Li", title = "Relative Perturbation Theory: {I}.

Novel ways to transform RPF to and from standard packed format are included. A new algorithm, called RPC for Recursive Packed Cholesky, that operates on the RPG format is presented. Algorithm RPC is basd on level-3 BLAS and requires variants of algorithms TRSM and SYRK that work on RPF. We call these RP\_TRSM and RP\_SYRK and find that they do most of their work by calling GEMM. It follows that most of the execution time of RPC lies in GEMM. The advantage of this storage scheme compared to traditional packed and full storage is demonstrated. First, the RPC storage format uses the minimal amount of storage for the symmetric or triangular matrix. Second, RPC gives a level-3 implementation of Cholesky factorization whereas standard packed implementations are only level 2. Hence, the performance of our RPC implementation is decidedly superior. Third, unlike fixed block size algorithms, RPC, requires no block size tuning parameter. We present performance measurements on several current architectures that demonstrate improvements over the traditional packed routines. Also MSP parallel computations on the IBM SMP computer are made. The graphs that are attached in Section 7 show that the RPC algorithms are superior by a factor between 1.6 and 7.4 for order around 1000, and between 1.9 and 10.3 for order around 3000 over the traditional packed algorithms.

When $f$ and $g$ are positive real numbers, this simply amounts to computing the values of $ c = f / \sqrt {f^2 + g^2} $, $ s = g / \sqrt {f^2 + g^2} $, and $ r = \sqrt {f^2 + g^2} $. This apparently trivial computation merits closer consideration for the following three reasons. First, while the definitions of $c$, $s$ and $r$ seem obvious in the case of two nonnegative arguments $f$ and $g$, there is enough freedom of choice when one or more of $f$ and $g$ are negative, zero or complex that LAPACK auxiliary routines SLARTG, CLARTG, SLARGV and CLARGV can compute rather different values of $c$, $s$ and $r$ for mathematically identical values of $f$ and $g$. To eliminate this unnecessary ambiguity, the BLAS Technical Forum chose a single consistent definition of Givens rotations that we will justify here. Second, computing accurate values of $c$, $s$ and $r$ as efficiently as possible and reliably despite over/underflow is surprisingly complicated. For complex Givens rotations, the most efficient formulas require only one real square root and one real divide (as well as several much cheaper additions and multiplications), but a reliable implementation using only working precision has a number of cases.

The new BLAS are challenging to implement and test because there are many more subroutines than in the existing Standard, and because we must be able to assess whether a higher precision is used for internal computations than is used for either input or output variables. We have therefore developed an automated process of generating and systematically testing these routines. Our methodology is applicable to languages besides C.

The extra precision calculation is facilitated by the new extended-precision BLAS standard in a portable way, and the refinement algorithm will be included in a future release of LAPACK and can be extended to the other types of least squares problems.", acknowledgement = ack-nhfb, articleno = "28", fjournal = "ACM Transactions on Mathematical Software (TOMS)", journal-URL = "http://dl.acm.org/pub.cfm?id=J782", keywords = "BLAS; floating-point arithmetic; LAPACK; Linear algebra", remark = "Journal publication of LAWN 188 \cite{Demmel:2007:EPI}.", } %%% ==================================================================== %%% Cross-referenced entries must come last: @Proceedings{Burkhart:1990:CVI, editor = "H.
