NAME

       futhark-pyopencl - compile Futhark to Python and OpenCL

SYNOPSIS

       futhark pyopencl [options…] infile

DESCRIPTION

       futhark  pyopencl  translates  a Futhark program to Python code invoking OpenCL kernels, which depends on
       Numpy and PyOpenCL.  By default, the program uses the first device of the first OpenCL  platform  -  this
       can be changed by passing -p and -d options to the generated program (not to futhark pyopencl itself).

       The  resulting  program  will  otherwise  behave  exactly  as  one  compiled  with futhark py.  While the
       sequential host-level code is pure Python and just as slow as in futhark py, parallel sections will  have
       been  compiled to OpenCL, and runs just as fast as when using futhark opencl.  The kernel launch overhead
       is significantly higher, however, so a good rule of thumb when using  futhark  pyopencl  is  to  aim  for
       having fewer but longer-lasting parallel sections.

       The generated code requires at least PyOpenCL version 2015.2.

OPTIONS

       Accepts the same options as futhark-opencl.
