SUMMARY:Accelerating quantum many-body configuration interaction with dire
 ctives
DESCRIPTION:Workshop\n\nAccelerating quantum many-body configuration inter
 action with directives\n\nCook, Fasano, Maris, Yang, Oryspayev\n\nMany-Fer
 mion Dynamics-nuclear, or MFDn, is a configuration interaction (CI) code f
 or nuclear structure calculations. It is a platform independent Fortran~90
  code using a hybrid MPI+X programming model. For CPU platforms the applic
 ation has a robust and optimized OpenMP implementation for shared memory p
 arallelism. As part of the NESAP application readiness program for NERSC's
  latest Perlmutter system, MFDn has been updated to take advantage of acce
 lerators. The current mainline GPU port is based on OpenACC. In this work 
 we describe some of the key challenges of creating an efficient GPU implem
 entation. We compare the support of OpenMP and OpenACC on AMD and NVIDIA G
 PUs.\n\nTag: Online Only, Accelerator-based Architectures, Parallel Progra
 mming Languages and Models, Performance, State of the Practice\n\nRegistra
 tion Category: Workshop Reg Pass
