Project description
f2py-jit
Just-in-time compilation of Fortran code in Python via f2py.
Documentation
Quick start
Start from a piece of Fortran code.f90
subroutine hello()
print*, "Hello world!"
end subroutine
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
"""
f90 = jit(source)
f90.hello()
If the Fortran source contains multiple subroutines calling each other, f2py
will not perform interprocedural optimizations (at least not by default). f2py_jit
can inline the source code before compiling it, and you will get a performace boost [This feature is experimental]
f90 = jit('code.f90', inline=True)
Features
- Compilation of source blocks as python strings
- Caching of module builds across executions
- Optional inlining to improve performance (experimental)
Dependencies
- numpy
- Fortran compiler
Installation
From pip
pip install f2py-jit
From source
