********************************* ATLAS TEAM **********************************
ATLAS is currently developed and maintained by R. Clint Whaley at the
University of Texas at San Antonio. Several UTSA students/staff have made
strong contributions, including Tony Castaldo and Siju Samuel. The
present ATLAS team is:
Clint Whaley, PI
Tony Castaldo, Research Professor
Md. Rakib Hasan, PhD candidate: parallel algorithms
Md. Majedul Haque Sujon, PhD candidate: iterative compilation
ATLAS was originally developed at the Innovative Computing Laboratory (ICL),
at the University of Tennessee, though no team members remain there now.
The original ATLAS team was:
Antoine Petitet
petitet@cs.utk.edu
** Recursive Level 3 BLAS
** Codeveloped Level 2 gemv- & ger-based BLAS
** Codeveloped ATLAS level 2 blas tester
** Reference BLAS
** BLAS F77 interface
** Developed original pthreads implementation
** Level 2 packed and banded gemv- and ger-based BLAS
** Level 1 BLAS tester/timer
R. Clint Whaley
whaley@cs.utsa.edu
** General ATLAS design
** config, install & tuning routines
** Matrix multiply
** Code generators for real & complex matrix multiply
** Kernel routines used in the recursive Level 3 BLAS
** Codeveloped Level 2 gemv- & ger-based BLAS
** Codeveloped ATLAS level 2 blas tester
** GEMV & GER and associated files
** C interface to BLAS
** Recursive LU, Cholesky, xLAUUM and xGETRI routines and testers
** LAPACK interfaces
** ATLAS Level 1 BLAS routines
** Tools and docs necessary to allow user contribution of all kernels
** Quite a few GEMV, GER, and GEMM kernels
** New threading infrastructure (as of 3.9.5)
** Help with new QR design and some coding, some help with qr tester,
and wrote the C/F77 interface files for all QR variants (see
Siju Samuel for more details on QR)
-> Pretty much anything not attributed to someone else :)
During the original development at UTK, Jeff and Peter also helped out:
Jeff Horner
jhorner@cs.utk.edu
** Level 3 BLAS tester/timer
** Beta versions of
** Non-generated complex matrix multiply code
** C interface to the Level 3 BLAS
Peter Soendergaard
soender@cs.utk.edu
** Recursive xTRTRI and tester
ATLAS has been modified to allow for outside contribution, and the
following people have contributed to ATLAS (alphabetic order):
Doug Aberdeen
** Work on emmerald (an SSE-enabled SGEMM) was the starting point
for a lot of the people doing SSE-enabled kernels.
Matthew Brett
** Help with getting ATLAS to build dynamic libraries.
** Lots of help in switching from CVS/sourceforge to git/github
** Provided basis for ATLAS/git documentation by creating
first version gitwash subdir now in AtlasBase/TexDoc/gitwash
Tony Castaldo (2008, 2009, 2012)
** UTSA student and research professor.
** Figured out PowerPC970 required issuing 4 inst of same type in a row,
and intermixing of M-loop iterations for full performance.
** Discovered the importance of master-last, leading to full threading
rewrite.
** Did main prototyping and helped with design of the of ATLAS
QR variants. See Siju Samuel entry for more details.
** Main developer of PCA QR panel factorization prototype code
Nicholas Coult
** Initial version of AltiVec enabled SGEMM.
Markus Dittrich
** Provided the trick needed to get configure to pass multiple words
as a single flag in configure.
Saurabh Garg
** Help with building MSVC++ compatible shared libraries. See:
https://sf.net/projects/math-atlas/forums/forum/1026734/topic/5349864
Dean Gaudet
** CPUID for config (see ATLAS/CONFIG/archinfo_x86.c), Efficeon tuning
information, and many informative atlas-devel discussions.
Kazushige Goto
** Assembly language GEMM for Compaq/DEC ev5x and ev6 machines. See
ATLAS/src/blas/gemm/GOTO for details. Code no longer in ATLAS
v > 3.7.12, as we have dropped support for alphas.
Md. Rakib Hasan
** UTSA student. Wrote ARM NEON kernels for GER2K.
See ATLAS/tune/blas/gemv/MVTCASES/ATL_sger2K_NEON*.S for details.
Camm Maguire
** SSE enabled [S,D,C,Z]GEMM, [S,D,C,Z]GEMV and [S,D,C,Z]GER kernels,
see ATLAS/tune/blas/gemm/CASES, ATLAS/tune/blas/gemv/CASES
and ATLAS/tune/blas/ger/CASES for details.
Ryan Moon (2009)
** Wrote the first version of the OpenMP Level 3 threaded BLAS
based on the new threading framework while an undergrad at UTSA.
See ATLAS/src/threads/blas/level3/omp for details.
Tim Mattox and Hank Dietz
** Extremely efficient 3DNow! kernel for Athlon, see
ATLAS/tune/blas/gemm/CASES/ATL_smm_3dnow_90.c for details.
Viet Nguyen and Peter Strazdins
** UltraSparc-optimized [D,Z]GEMM kernels, see
ATLAS/tune/blas/gemm/CASES for details.
Pearu Peterson
** A lot of 3.6 stable testing.
** Initial work on building ATLAS to dynamic libraries.
Julian Ruhe
** Excellent Athlon-optimized assembly kernels, see
ATLAS/tune/blas/gemm/CASES/objs/ for details.
Siju Samuel (2009)
** UTSA student. Took prototype QR factorization written by Tony
Castaldo (mostly based on the Elmroth & Gustavson recursive QR, see
www.cs.utsa.edu/~whaley/papers/ppopp143-castaldo.pdf for details)
and wrote native implementations of all required QR variants.
See ATLAS/src/lapack for all the QR/RQ/QL/LQ related files,
and ATLAS/bin/qrtst.c for their tester.
** Took Tony Castaldo's prototype QR PCA code and produced versions for
QR and LQ for all precisions for parallel lapack
Peter Soendergaard
** SSE and 3DNow! GEMM routines. See ATLAS/tune/blas/gemm/CASES
for details. Also, translation of Julian Ruhe's Athlon kernels
from NASM to gnu assembler, and extension to all precisions.
See ATLAS/tune/blas/gemm/CASES/ATL_dmm_julian_gas_30.c for details.
Carl Staelin
** Initial work on parallelizing ATLAS make.
Md. Majedul Haque Sujon
** UTSA student. Wrote ARM NEON kernel for transpose GEMV.
See ATLAS/tune/blas/gemv/MVTCASES/ATL_sgemvT_8x4_neon.S for details.
Yevgen Voronenko
** Provided code template for Core2Duo-friendly 2-D register block
which allowed us to greatly increase our Core2Duo GEMM performance.
See ATLAS/tune/blas/gemm/CASES/ATL_dmm4x2x128_sse2.c for details.
Tom Wallace (2011, 2012)
** Did a lot of work on adding ARM support to ATLAS's configure, as
well as some tuning for the ARM. Also, a lot of testing and
submission of patches. Provided ARM NEON s/c GEMM kernel.
Chad Zalkin (2009)
** Wrote code generator which uses gcc intrinsics to autovectorize and
tune matrix multiply. Contributed to the search over the same.
See ATLAS/tune/blas/gemm/mmgen_sse.c and
ATLAS/tune/blas/gemm/mmksearch_sse.c for details.
