Abstract
Scalability of computations in the FlowVision CFD software on the Angara-C1 cluster equipped with the Angara interconnect is studied. Different test problems with 260 thousand, 5.5 million and 26.8 million computational cells are considered. Computations in FlowVision are performed using a new solver of linear systems based on the algebraic multigrid (AMG) method. It is shown that the the special FlowVision’s Dynamic balancing technology significantly improves performance of computations if features of the problem lead to the non-uniform loading of CPUs. The Angara-C1 cluster demonstrates excellent performance and scalability characteristics comparable with its analogues based on the 4X FDR Infiniband interconnect.
