6.16 Memory Options and Parallelization of Coupled-Cluster Calculations

6.16.1 Introduction

(February 4, 2022)

The coupled-cluster suite of methods, which includes ground-state methods mentioned earlier in this Chapter and excited-state methods in the next Chapter, has been parallelized to take advantage of distributed memory and multi-core architectures. The code is parallelized at the level of the underlying tensor algebra library.303
