| 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. |
