Performance Engineering for Real and Complex Tall & Skinny Matrix Multiplication Kernels on GPUs
Dominik Ernst, Georg Hager, Jonas Thies +1
General matrix-matrix multiplications with double-precision real and complex entries (DGEMM and ZGEMM) in vendor-supplied BLAS libraries are best optimized for square matrices but…
Chebyshev Filter Diagonalization on Modern Manycore Processors and GPGPUs
Moritz Kreutzer, Georg Hager, Dominik Ernst +3
Chebyshev filter diagonalization is well established in quantum chemistry and quantum physics to compute bulks of eigenvalues of large sparse matrices. Choosing a block vector impl…
A unified sparse matrix data format for efficient general sparse matrix-vector multiply on modern processors with wide SIMD units
Moritz Kreutzer, Georg Hager, Gerhard Wellein +2
Sparse matrix-vector multiplication (spMVM) is the most time-consuming kernel in many numerical algorithms and has been studied extensively on all modern processor and accelerator…
