V. Yu. Kolobyanin, A. A. Fedorov, N. P. Antipina
VANT. Ser.: Mat. Mod. Fiz. Proc 2017. Вып.3. С. 62-69.

The paper describes the two-level paralleling (in shared memory and distributed memory) of explicit difference schemes in the EGAK code. The transfer from the one-level paralleling model (in distributed memory) to the two-level model is described. Results of numerical scalability tests are presented.

Keywords: the EGAK code, two-level paralleling, paralleling efficiency, parallel computers.
