[petsc-users] CUDA with complex number

[Barry Smith]

    This is an installation issue, please send all installation issues to petsc-maint at mcs.anl.gov with the entire configure.log

     


   You can try editing config/PETSc/packages/cuda.py and removing the two lines 

    if self.scalartypes.scalartype == 'complex':
      raise RuntimeError('Must use real numbers with CUDA') 

   As it says we have never tested for complex so I do not know how far it is from working.
