OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of compute technologies. APSR – an efficient parallel random resource management algorithm that requires information only from a small number of hosts and dynamically adjusts the degree of parallelism to provide provable decline ratio guarantees
Implementation copywriter: Or Peres - pereo@post.bgu.ac.il ,Liron Cohen- cohenlir@post.bgu.ac.il
This is implementation of article "Parallel Virtual Machine Placement with Provable Guarantees" Supervisors: Dr. Scalosub Gabriel Dr. Einziger Gil
Note: APSR scheduler replace the filter schedulers
- Start by cloning this project.
- Run scripts
- 0-prepare.sh
- This command is to prepare the installed OpenStack environment before the 1st benchmarking. It replace the nova code to support the APSR vertion. The scrip also create the configuration file.
- 1-run_APSR.sh
- This start the APSR controller
You can find all APSR configuration at - /etc/nova/APSR_CONFIG.txt
[DEFAULT]
#determine how often the APSR controller will work
INTERVAL_SIZE = 10
# parameters for APSR algorithm estimate K factor
ALPHA = 0.1
# APSR's target decline ratio (0.1)
EPSILON = 0.1
# Set the APSR type, 0 - APSR , 1- APSR AVG
TYPE = 0
#Budget for overall number of queries
BUDGET_SIZE = 100
#APSR is allow to open up to MAX_SCHDULERS schedulers
MAX_SCHDULERS = 100
In order to debug the project you can use-
- APSR log file - /lib/python2.7/site-packages/nova/APSR_CONTROLLER.log
- Nova logs - /var/log/nova/*
