dbcsr: dbcsr (Distributed Block Compressed Sparse Row matrix library) dbcsr: dbcsr: DBCSR is a library designed to efficiently perform sparse dbcsr: matrix-matrix multiplication, among other operations. It is MPI and dbcsr: OpenMP parallel and can exploit Nvidia and AMD GPUs via CUDA and HIP. dbcsr: dbcsr: dbcsr: dbcsr: dbcsr: dbcsr:
