DAMON: Data Access MONitor |
|
========================== |
|
|
|
DAMON is a data access monitoring framework subsystem for the Linux kernel. |
|
The core mechanisms of DAMON (refer to :doc:`design` for the detail) make it |
|
|
|
- *accurate* (the monitoring output is useful enough for DRAM level memory |
|
management; It might not appropriate for CPU Cache levels, though), |
|
- *light-weight* (the monitoring overhead is low enough to be applied online), |
|
and |
|
- *scalable* (the upper-bound of the overhead is in constant range regardless |
|
of the size of target workloads). |
|
|
|
Using this framework, therefore, the kernel's memory management mechanisms can |
|
make advanced decisions. Experimental memory management optimization works |
|
that incurring high data accesses monitoring overhead could implemented again. |
|
In user space, meanwhile, users who have some special workloads can write |
|
personalized applications for better understanding and optimizations of their |
|
workloads and systems. |
