The + computationally most intensive phase, factorization, is accelerated via + randomized linear algebras. The butterfly format, originally inspired by + the butterfly data flow in fast Fourier Transform, is a linear algebra tool + well-suited for compressing matrices arising from high-frequency wave + equations or highly oscillatory integral operators.""" + + homepage = "https://github.com/liuyangzhuan/ButterflyPACK" + git = "https://github.com/liuyangzhuan/ButterflyPACK.git" + + maintainers = ['liuyangzhuan'] + + version('master', branch='master') + + variant('shared', default=True, description='Build shared libraries') + + depends_on('mpi') + depends_on('blas') + depends_on('lapack') + depends_on('scalapack') + depends_on('arpack-ng') + + def cmake_args(self): + spec = self.spec + + def on_off(varstr): + return 'ON' if varstr in spec else 'OFF' + + args = [ + '-DCMAKE_C_COMPILER=%s' % spec['mpi'].mpicc, + '-DCMAKE_Fortran_COMPILER=%s' % spec['mpi'].mpifc, + '-DCMAKE_CXX_COMPILER=%s' % spec['mpi'].mpicxx, + '-DTPL_BLAS_LIBRARIES=%s' % spec['blas'].libs.joined(";"), + '-DTPL_LAPACK_LIBRARIES=%s' % spec['lapack'].libs.joined(";"), + '-DTPL_SCALAPACK_LIBRARIES=%s' % spec['scalapack']. + libs.joined(";"), + '-DTPL_ARPACK_LIBRARIES=%s' % spec['arpack-ng'].libs.joined(";"), + ] + + args.extend([ + '-DBUILD_SHARED_LIBS=%s' % on_off('+shared') + ]) + + return args |
