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.
