USAGE OF FORTRAN DVMH LANGUAGE FOR SOLVING HYDRODYNAMICS PROBLEMS ON HYBRID COMPUTING SYSTEMS

Abstract

In  the  2011  year  DVMH  programming  model  for  new  heterogeneous  and  hybrid supercomputer  systems  (or  DVM  for  Heterogeneous  systems)  was  introduced  in  the  Keldysh  Institute  for Applied  Mathematics  of  RAS.  The  developed  high-level  programming  languages  were  based  on standard  Fortran  and  C  programming  languages,  but  extended  with  the  directives  for  mapping the  program  onto  a  parallel  computer.  The  directives  are  represented  as  special  comments  (or pragmas). The paper includes analysis of the efficiency of the developed programs for solving the hydrodynamics problems «Cavity» and «Container». The  calculation results are gained by using several thousand CPU cores and gained by using morethan 1200 GPU accelerators are presented.
