MP2-R12 Performance

Below is the speedup with respect to the wall time on one node as a function of the number of nodes utilized in a parallel computation of valence aug-cc-pCVTZ/K2-- MP2-R12/A' energy of benzene molecule. SLB and DLB refer to static and dynamic load balancing, respectively.



Below is the parallel efficiency as a function of the number of nodes for the above test case.
