loki.backend.cufgen

cufgen(ir, style=None, depth=0)

Generate CUDA Fortran code from one or many IR objects/trees.

Implemented by extending the FortranCodegen to support CUDA Fortran specific syntax. Refer to the CUDA_FORTRAN_PROGRAMMING_GUIDE for more information.

Supported subset of the CUDA Fortran specifications:

• variable qualifiers e.g. attributes(device)

• chevron syntax for to launch kernels e.g. call kernel<<<grid,block[,bytes][,streamid]>>>(arg1,arg2,...)

Natively supported (via FortranCodegen):

• subroutine/function qualifiers e.g. attributes(global) via loki.Subroutine.prefix

• kernel loop directives via loki.ir.Pragma
