In this project, we exploit to utilize the opportunitisc memory for opportunistic jobs (often used for best-effort jobs). Charon is composed of on two components:
(1) Kernel augmentation. We implement UA killer in kernel space to select oom candidates to kill in a timely and informative manner.
(2) Charon implementation in NodeManager of Mercury, a daemon thread to monitor node memory and launch containers.
For more information, please refer our paper (Currently under submission).
To build this project, plesse refer BUILDING.txt for detail. My codebase is built on Hadoop-3.0.0.
Our kernel implementation of UA killer is in this: https://github.com/yncxcw/UAkiller repo. Please downlaod and install the modified linux kernel as:
make -j(number of CPU cores)
make install
make modules_install
After installing, the cgth_time can be set by:
echo 3 > /pro/sys/vm/cgth_time
We are still sorting the scripts we use to parse the Google trace. The setup of simulator will be available soon.
