Abstract

Sandia and Los Alamos National Laboratories are acquiring Trinity, a Cray XC40, with half of the nodes having Haswell processors and the other half having Knight's Landing processors. As part of our Center of Excellence with Cray, we are working on porting three codes, a Solid Mechanics code, a Structural Dynamics code, and an Aerodynamics code, to effectively use this machine. In this paper, we will detail the work that we have done in porting the codes in preparation of getting the machine. We have started by profiling the codes using tools including CrayPat, which showed that a large portion of the time is being spent in the solvers. We will describe the work we are doing on the solvers such as ongoing work on Haswell processors and Knight's Corner machines.
