CANDMC

##Communication Avoiding Numerical Dense Matrix Computations

Purpose:

This repository contains studies for algorithms to perform matrix multiplication and dense matrix factorizations, currently: LU, QR, and the symmetric eigensolve.

Requirements:

Some version of BLAS and LAPACK required for any build. LAPACK version 3.40 or higher required to build QR codes.

Build Instructions:

Running ./configure will generate a config.mk file with build parameters and a Makefile. See the configure file for build options. Profiling may be activated with flag -DPROFILE (add to DEFS in config.mk). After running configure, running 'make' will build the library and place it into lib/libCANDMC.a. Specific contents may be built individually,

  • library of all routines 'CANDMC'
  • library of all shared routines required for use of any individual algorithmic library component 'CANShared'
  • library for matrix multiplication algorithms 'CANMM'
  • library for LU factorization algorithms 'CANLU'
  • library for QR factorization algorithms 'CANQR'
  • library for symmetric eigensolve algorithms 'CANSE'
  • all unit tests 'test', executables appear in bin/tests/
  • all benchmarks 'bench', executables appear in bin/benchmarks/
