> This script parses the application configuration file and detects all the
> pipelines specified therein, and then, it generates all the possible mappings
> of those pipelines on the specified CPU core-list.
> 
> As a result, each of the possible pipeline-to-core mappings is saved as
> separate output configuration file. For example- if input file is
> edge_router_downstream.cfg with 3 pipeline (excluding pipeline 0) and
> core-list is “1, 2”, following combinations will be generated-
> 
> Pipeline 1        Pipeline 2      Pipeline 3
> Core = 1          Core = 1        Core = 2
> Core = 1          Core = 2        Core = 1
> Core = 2          Core = 1        Core = 1
> Core = 2          Core = 2        Core = 1
> Core = 2          Core = 1        Core = 2
> Core = 1          Core = 2        Core = 2
> Core = C1         Core = C1H      Core = C2
> Core = C1         Core = C2       Core = C1H
> Core = C2         Core = C1       Core = C1H

> This script will help users to analyse the performance of application by
> evaluating all the generated configuration files with different
> pipelines-to-core mappings and obtaining the application configuration file
> with best performance.
> 
> To run the script, issue the following command;
> 
> ./pipeline-to-core-mapping.py -i <input_configuration_file> -pc "s<socket-id>c<core-id>"
> 
> Some optional arguments are as follows:
>   -h, --help            show this help message and exit
>   -ht {ON,OFF}, --hyper-thread {ON,OFF}
>                         enable/disable hyper threading. default is ON
>   -nO, --no-output-file
>                         disable output config file generation. Output file
>                         generation is enabled by default

Applied

I am not sure we are still in the scope of an example here.
ip_pipeline looks to be a complete DPDK application.
