Revision as of 17:03, 9 February 2016
Several core algorithms of VASP have been ported to run on GPU-accelerated hardware (as of VASP.5.4.1.05Feb16).
- Explicity ported to run on GPU-accelerated hardware
- Electronic minimisation: the blocked-Davidson and RMM-DIIS algorithms (ALGO= Normal, Fast, and VeryFast).
- Hybrid functionals: the action of the Fock-exchange potential on the wave functions (LHFCALC=.TRUE.).
- Unsuported (for now)
- LREAL=.FALSE. is currently unsuported . The GPU port of VASP requires the use of real-space-projection operators (i.e., LREAL= Auto | .TRUE.).
- LCALCEPS=.TRUE.
- NCORE ≠ 1 (or equivalently: NPAR ≠ #of-MPI-ranks/KPAR) is not supported at the moment. The GPU port of VASP requires NCORE=1 (default).
- The gamma-only version of VASP has not been ported to GPU (yet).
N.B.: The GPU port of VASP is freely available to VASP5-licensees.
People
The GPU port of VASP only exist because of the excellent work of the following people:
- Maxwell Hutchinson (University of Chicago) and Mike Widom (Carnegie Mellon)
- Xavier Rozanska and Paul Fleurat-Lessard (ENS-Lyon)
- Mohamed Hacene, Ani Anciaux-Sedrakian, Diego Klahr, and Thomas Guignon (IFPEN)
