Enzo-E cosmology on Frontera: baseline weak scaling

by James Bordner | 2019-10-03 21:51 | ID: 221732 | 66,712 bytes |

This is a collection of scaling results of Enzo-E / Cello running a dark-matter only AMR cosmology test problem on the Frontera supercomputer at TACC. The weak scaling study goes from a 64^3 root grid 3.0/h comoving Mpc problem, up through 1024^3 root grid on 48.0/h comoving Mpc. Processor counts run from P=7 for 64^3 to 28672 (the factor of 7 is used because there are 56 available cores per node). Here are some projections from the 512^3 root-grid L=4 run
