fparser.scripts.fparser2_bench

Generates a large Fortran program in memory and then measures how long it takes fparser2 to parse it. This is based on the benchmark suggested by Ondřej Čertík via Ioannis Nikiteas.

Functions

`gen_sub`(num)	Constructs a Fortran subroutine named g<num>.
`create_bench`(num_routines)	Creates the Fortran benchmark code.
`runner`(num_routines)	Entry point for running the benchmark.

Module Contents

fparser.scripts.fparser2_bench.gen_sub(num: int)[source]

Constructs a Fortran subroutine named g<num>.

Parameters:: num – the number of the subroutine (used to name it).
Returns:: Fortran subroutine.
Return type:: str

fparser.scripts.fparser2_bench.create_bench(num_routines: int)[source]

Creates the Fortran benchmark code.

Parameters:: num_routines – the number of subroutines to create.
Returns:: benchmark Fortran code.
Return type:: str

fparser.scripts.fparser2_bench.runner(num_routines: int)[source]

Entry point for running the benchmark.

Parameters:: num_routines – the number of subroutines to create in the Fortran benchmark.
Raises:: ValueError – if num_routines < 1.
