Abstract:

Quantum ESPRESSO is an integrated suite for quantum mechanical materials modeling at the nanoscale. It is based on density-functional theory, plane waves, and pseudopotentials and is designed for highly scalable execution with a special focus on maintaining performance portability. It is actively developed by a large team of scientists and HPC experts and has a vast user community.

This talk will present how a 600k-line Fortran community code has been ported to GPUs by focusing in particular on the design choice that allowed to release a fully functional GPU accelerated version that provides substantial speedups on different architectures. Lessons learned from previous porting activities and remaining challenges will conclude the talk.
