Subject: [RFC v8 0/8] Implement Data Access Monitoring-based Memory Operation Schemes
From: SeongJae Park <sjpark@...zon.de>
DAMON[1] can be used as a primitive for data access awared memory management
optimizations. That said, users who want such optimizations should run DAMON,
read the monitoring results, analyze it, plan a new memory management scheme,
and apply the new scheme by themselves. Such efforts will be inevitable for
some complicated optimizations.
However, in many other cases, the users would simply want the system to apply a
memory management action to a memory region of a specific size having a
specific access frequency for a specific time. For example, "page out a memory
region larger than 100 MiB keeping only rare accesses more than 2 minutes", or
"Do not use THP for a memory region larger than 2 MiB rarely accessed for more
than 1 seconds".
This RFC patchset makes DAMON to handle such data access monitoring-based
operation schemes. With this change, users can do the data access aware
optimizations by simply specifying their schemes to DAMON.

Evaluations
===========
Setup
-----
On my personal QEMU/KVM based virtual machine on an Intel i7 host machine
running Ubuntu 18.04, I measure runtime and consumed system memory while
running various realistic workloads with several configurations. I use 13 and
12 workloads in PARSEC3[3] and SPLASH-2X[4] benchmark suites, respectively. I
personally use another wrapper scripts[5] for setup and run of the workloads.
On top of this patchset, we also applied the DAMON-based operation schemes
patchset[6] for this evaluation.
Measurement
~~~~~~~~~~~
For the measurement of the amount of consumed memory in system global scope, I
drop caches before starting each of the workloads and monitor 'MemFree' in the
'/proc/meminfo' file. To make results more stable, I repeat the runs 5 times
and average results. You can get stdev, min, and max of the numbers among the
repeated runs in appendix below.
Configurations
~~~~~~~~~~~~~~
The configurations I use are as below.
orig: Linux v5.5 with 'madvise' THP policy
rec: 'orig' plus DAMON running with record feature
thp: same with 'orig', but use 'always' THP policy
ethp: 'orig' plus a DAMON operation scheme[6], 'efficient THP'
prcl: 'orig' plus a DAMON operation scheme, 'proactive reclaim[7]'
I use 'rec' for measurement of DAMON overheads to target workloads and system
memory. The remaining configs including 'thp', 'ethp', and 'prcl' are for
measurement of DAMON monitoring accuracy.
'ethp' and 'prcl' is simple DAMON-based operation schemes developed for
proof of concepts of DAMON. 'ethp' reduces memory space waste of THP by using
DAMON for decision of promotions and demotion for huge pages, while 'prcl' is
as similar as the original work. Those are implemented as below:
# format: <min/max size> <min/max frequency (0-100)> <min/max age> <action>
# ethp: Use huge pages if a region >2MB shows >5% access rate, use regular
# pages if a region >2MB shows <5% access rate for >1 second
2M null 5 null null null hugepage
2M null null 5 1s null nohugepage
# prcl: If a region >4KB shows <5% access rate for >5 seconds, page out.
4K null null 5 500ms null pageout
Note that both 'ethp' and 'prcl' are designed with my only straightforward
intuition, because those are for only proof of concepts and monitoring accuracy
of DAMON. In other words, those are not for production. For production use,
those should be tuned more.

DAMON Overheads
~~~~~~~~~~~~~~~
In total, DAMON recording feature incurs 0.70% runtime overhead and 0.03%
memory space overhead.
For convenience test run of 'rec', I use a Python wrapper. The wrapper
constantly consumes about 10-15MB of memory. This becomes high memory overhead
if the target workload has small memory footprint. Nonetheless, the overheads
are not from DAMON, but from the wrapper, and thus should be ignored. This
fake memory overhead continues in 'ethp' and 'prcl', as those configurations
are also using the Python wrapper.
Efficient THP
~~~~~~~~~~~~~
THP 'always' enabled policy achieves 4.76% speedup but incurs 7.05% memory
overhead. It achieves 37.37% speedup in best case, but 81.79% memory overhead
in worst case. Interestingly, both the best and worst case are with
'splash2x/ocean_ncp').
The 2-lines implementation of data access monitoring based THP version ('ethp')
shows 2.34% speedup and 2.60% memory overhead. In other words, 'ethp' removes
63.12% of THP memory waste while preserving 49.15% of THP speedup in total. In
case of the 'splash2x/ocean_ncp', 'ethp' removes 62.94% of THP memory waste
while preserving 57.37% of THP speedup.
Proactive Reclamation
~~~~~~~~~~~~~~~~~~~~
As same to the original work, I use 'zram' swap device for this configuration.
In total, our 1 line implementation of Proactive Reclamation, 'prcl', incurred
8.41% runtime overhead in total while achieving 5.83% system memory usage
reduction.
Nonetheless, as the memory usage is calculated with 'MemFree' in
'/proc/meminfo', it contains the SwapCached pages. As the swapcached pages can
be easily evicted, I also measured the residential set size of the workloads:

In total, 19.89% of residential sets were reduced.
With parsec3/freqmine, 'prcl' reduced 85.85% of residential sets and 21.98% of
system memory usage while incurring only 2.42% runtime overhead.
Baseline and Complete Git Tree
==============================
The patches are based on the v5.6 plus v11 DAMON patchset[1] and Minchan's
``do_madvise()`` patch[2]. Minchan's patch was necessary for reuse of
``madvise()`` code in DAMON. You can also clone the complete git tree:
$ git clone git://github.com/sjp38/linux -b damos/rfc/v8
The web is also available:
https://github.com/sjp38/linux/releases/tag/damos/rfc/v8
The latest DAMON development tree is also available at:
https://github.com/sjp38/linux/tree/damon/master
[1] https://lore.kernel.org/linux-mm/20200511123302.12520-1-sjpark@amazon.com/
[2] https://lore.kernel.org/linux-mm/20200302193630.68771-2-minchan@kernel.org/
Sequence Of Patches
===================
The first patch allows DAMON to reuse ``madvise()`` code for the actions. The
second patch accounts age of each region. The third patch implements the
handling of the schemes in DAMON and exports a kernel space programming
interface for it. The fourth patch implements a debugfs interface for the
privileged people and programs. The fifth and sixth patches each adds kunit
tests and selftests for these changes, and the seventhe patch adds human
friendly schemes support to the user space tool for DAMON. Finally, the eighth
patch documents this new feature in the document.
