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
