Re: [Starpu-devel] Fortran interface for StarPU

[Alfredo Buttari <alfredo.buttari@enseeiht.fr>]

Dear Olivier,

I've followed your commits on the SVN repository over this last few days but did not have time to test the Fortran interface. I have to say, though, that it looks very neat and I am looking forward to give it a spin. I'll let you have some feedback ASAP.

ciao

Alfredo

Hi Alfredo,

I finally found some time to integrate this within StarPU, together with a few additional tweaks.

I made some modifications to the proposal so as to make it possible to write native Fortran applications on top of StarPU, without having to write C code at all on the application side.

The currently supported Fortran StarPU functions are listed in STARPU/include/fstarpu_mod.f90

Some examples are available in STARPU/examples/native_fortran/. This directory also contains autonomous Makefiles to compile them from outside the StarPU build system.

Somes notes:
- fully native Fortran apps are supported with GFortran >= 4.9 and Intel Fortran >= 2016. I have not yet tested this with other compiler brands.
- the Fortran task implementation functions have to be declared in a module outside the main program source file, to avoid some link-time issue.
- the native Fortran interface is available in StarPU's SVN repository, in the trunk/ and in the starpu-1.2/ branches.

Please let me know if you have any suggestion, or need some additional key C StarPU functions in the Fortran interface.

Best regards,

Olivier
