Subject: DAMON Quaterly News Letter (2024 Q1)

Message-ID: <20240402191224.92305-1-sj@kernel.org> (raw)
Hello DAMON community,
Already the first quater of 2024 has passed. Meanwhile, there were some
exciting news on DAMON community. Let me share my humble summary of those.
Januarry 2024
=============
Memory management subsystem pull request[1] for Linux v6.8-rc1 that contains
aim-oriented user-feedback driven DAMOS aggressiveness auto-tuning has merged.
SK Hynix shared[2] their DAMOS-based tiered memory management test results
showing 4-17% performance slowdown reduction, with patches for that.
LSF/MM/BPF 2024 topic proposal for DAMON has posted[3].
February 2024
=============
DAMON in Amazon Linux 5.10.y kernel[4] has updated to that of v6.7 Linux
kernel.
DAMON talk for OSSummit NA 2024 has been accepted and scheduled[5].
DAMO v2.2.2 is released with a new command, 'replay'[6]. It is aimed to help
reproducing the real-world memory access pattern for analysis and benchmarks.
Yet another academic paper[7] exploring DAMON for tiered memory management will
be presented at EuroSys 2024[8].
March 2024
==========
DAMO v2.2.4 is released with a new feature for access pattern-based
profiling[9]. Users can know which code is making their program's memory usage
unexpectedly high, or which code is intensively accessing memory, and optimize.
DAMON maintainer received the invitation for LSF/MM/BPF 2024.
Memory management subsystem pull request[10] for Linux 6.9-rc1 that contains
aim-oriented self-feedback driven DAMOS aggressiveness auto-tuning has merged.

To recap, the long-awaited DAMOS auto-tuning feature has merged. More people
from the academy and the industry explored and contributed on DAMON. DAMON
user-space tool got more useful features. We will have yet another DAMON
presentation and discussion at OSSummit NA and LSF/MM/BPF.
It was a grateful quarter. Looking forward to next news of the second quarter.
Happy second quarter and hacking, community!
Thanks,
SJ
