======================================================================== README for Python PQoS Library Wrapper examples April 2019 ======================================================================== Contents ======== - Overview - List of examples - Legal Disclaimer Overview ======== This folder contains examples how to use Python Wrapper for PQoS Library. Examples are simple scripts presenting usage of allocation, capabilities, CPU information, L2/L3 cache allocation and memory bandwidth allocation as well as cache and memory bandwidth monitoring. To run the examples it is needed to install virtual environment first (if not created): make env It will create Python 3 virtual environment with PQoS Library Python wrapper in env/. Then the example may be run by executing the script using installed Python environment (please note they require root privileges, so it might be needed to run them as root or with sudo). To display help message, -h flag can be used: ./env/bin/python <PATH_TO_SCRIPT> -h or source env/bin/activate python <PATH_TO_SCRIPT> -h For example: ./env/bin/python monitoring.py -h or source env/bin/activate python monitoring.py -h List of examples ================ 1) association.py The aim of this script is to configure/show association of class of service (COS) to cores. 2) l2ca.py The example of setting bit masks for L2 CAT classes of service and displaying associated bit masks. 3) l3ca.py It presents how to set bit masks for L3 CAT classes of service and display configured bit masks. 4) mba.py This script allows to set MBA rate values for classes of service and display their configuration. 5) monitoring.py The example of monitoring cache and memory bandwidth per core or per process. 6) reset_allocation.py It allows to reset all COSes to system default bit masks (CAT) and rate values (MBA).
