f2py-jit 0.5.0

No project description provided

f2py-jit

Just-in-time compilation of fortran code in python (via f2py).

Quick start

Start from a piece of Fortran code.f90

subroutine hello()
  print*, "Hello world!"
end subroutine hello

Compile the code, import it and execute it

from f2py_jit import jit
f90 = jit('code.f90')
f90.hello()

Do the same but from a python string containing the source block

source = """
subroutine hello()
  print*, "Hello world!"
end subroutine hello
"""
f90 = jit(source)
f90.hello()

If the fortran 90 source contains multiple subroutines calling one another, f2py will not perform interprocedural optimizations (at least not by default). f2py_jit can inline the source code before compiling it, and you should get a little performace boost [This feature is experimental, check the results]

from f2py_jit import jit, inline
f90 = jit(inline('code.f90'))
f90.hello()

Features

• Compilation of source blocks as python strings
• Caching of modules build across executions
• Optional inlining of Fortran code to improve performance (experimental)

Dependencies

• numpy

Installation

The easiest way to install f2py-jit is with pip

pip install f2py-jit

Alternately, you can clone the code repository and install from source

git clone https://framagit.org/coslo/f2py-jit.git
cd f2py_jit
make install
