(JP) GPGPUがPostgreSQLを加速する
http://www.insight-tec.com/dbts-tokyo-2014.html
--------
CPU/GPUという特性の異なるプロセッサの得意分野を組み合わせて費用・電力対性能の向上を狙うヘテロジニアス計算技術は、近年の半導体技術のトレンドの一つです。
本セッションでは、SQLワークロードのうちCPU負荷の高いロジックをGPUにオフロードする事で安価に検索処理の高速化を実現するPostgreSQL用の拡張モジュール PG-Strom と、GPGPUをはじめとする周辺技術についてご紹介します。
Control your service resources with systemd
This document discusses using systemd to manage control groups (cGroups) and set resource limits for processes and services. It describes how systemd simplified cGroup management by creating a cGroup for each service and allowing configuration via service files and drop-in files. Specific configuration options like memory and CPU limits can be set directly in the service file, via a slice file that multiple services reference, or using systemctl commands. Systemd provides unified management of cGroups and services.
Netflix Open Source Meetup Season 4 Episode 1
This document summarizes Netflix's efforts to evolve their open source projects. It discusses establishing clear ownership and lifecycles for projects (active, retired, experimental). It also describes a new dashboard called the Netflix OSS Tracker to monitor project health metrics. The rest of the document demonstrates this Spinnaker continuous delivery platform that Netflix has open sourced and discusses Google's involvement in contributing to and adopting Spinnaker.
Top 5 benefits of docker
Recording here: https://www.youtube.com/watch?v=5W4n9K3PIVg
Since Docker was open sourced in 2013, the community and adoption around Docker containers has grown to over 6 billion downloads and over 1000 contributors. Learn about why this is, and why you should start using containers for your own applications.
明日からはじめられる Docker + さくらvpsを使った開発環境構築
Amazon EC2 Container Service をはじめ、 Docker ベースのサービスが徐々に本番環境に導入されはじめてきています。 改めて Docker とはどのようなものなのか、 VMWare や VirtualBox など、従来の仮想環境と何が違うのかについて触れていきます。
また、開発環境を VPS 上に構築することで、チーム全体のパフォーマンスを向上させたり、ローカルマシンとサーバー上のデータをリアルタイムで同期させる他、マルチドメインに対応させることで、複数の開発メンバーが同時に開発環境にアクセスできるようにするなど、 Docker を使った開発がより楽しく便利になる方法についてお話しました。
[KubeCon NA 2020] containerd: Rootless Containers 2020
Rootless Containers means running the container runtimes (e.g. runc, containerd, and kubelet) as well as the containers without the host root privileges. The most significant advantage of Rootless Containers is that it can mitigate potential container-breakout vulnerability of the runtimes, but it is also useful for isolating multi-user environments on HPC hosts. This talk will contain the introduction to rootless containers and deep-dive topics about the recent updates such as Seccomp User Notification. The main focus will be on containerd (CNCF Graduated Project) and its consumer projects including Kubernetes and Docker/Moby, but topics about other runtimes will be discussed as well.

10GbE時代のネットワークI/O高速化
10GbE、40GbEなどの極めて高速な通信をサポートするNICが、PCサーバの領域でも使われるようになってきている。
このような速度の通信をソフトウェア（OS）で処理し高い性能を得るには様々な障害があり、ハードウェア・ソフトウェア両面の実装を見直す必要がある。
本セッションでは、ハードウェア・ソフトウェア両面にどのような改良が行われてきており、性能を引き出すにはどのようにこれらを使用したらよいのかについて紹介する。
The Forefront of the Development for NVDIMM on Linux Kernel (Linux Plumbers c...
The document summarizes the current status and issues with NVDIMM support on the Linux kernel, specifically with Filesystem Direct Access (DAX). It discusses two main issues that have made Filesystem DAX experimental: 1) updating metadata when data is written directly without going through the page cache, and 2) unbinding a namespace that is currently in use can forcibly remove it. It also covers other challenges like enabling/disabling DAX on a per-inode basis and supporting copy-on-write features with a DAX filesystem. The presentation will go into more details on solving specific issues like supporting reflink/dedupe for filesystem DAX and fixing reverse mapping with NVDIMM.

Quarkus - a next-generation Kubernetes Native Java framework
For years, the client-server architecture has been the de-facto standard to build applications. But a major shift happened. The one model rules them all age is over. A new range of applications and architectures has emerged and impacts how code is written and how applications are deployed and executed. HTTP microservices, reactive applications, message-driven microservices, and serverless are now central players in modern systems.
Quarkus has been designed with this new world in mind and provides first-class support for these different paradigms. Developers using the Red Hat build of Quarkus can now choose between deploying natively compiled code or JVM-based code depending on an application’s needs. Natively compiled Quarkus applications are extremely fast and memory-efficient, making Quarkus a great choice for serverless and high-density cloud deployments.

Rootless Containers
In this talk we will discuss how to build and run containers without root privileges. As part of the discussion, we will introduce new programs like fuse-overlayfs and slirp4netns and explain how it is possible to do this using user namespaces. fuse-overlayfs allows to use the same storage model as "root" containers and use layered images. slirp4netns emulates a TCP/IP stack in userland and allows to use a network namespace from a container and let it access the outside world (with some limitations).
We will also introduce Usernetes, and how to run Kubernetes in an unprivileged user namespace

Kvm
This document provides an introduction to KVM (Kernel-based Virtual Machine), an open source hypervisor that allows running multiple operating systems on a single computer. KVM is integrated into the Linux kernel since version 2.6.20 and provides full virtualization capabilities. It supports hardware virtualization features, sound, snapshots, PCI passthrough, live migration, and more through a layered model. KVM can be managed through tools like Libvirt, Virsh, and Ovirt and is well-suited for cloud computing due to its security, speed, scalability, and reliability.

RTOS入門 タスク概要
- 2. タスクとは • タスクとは、複数の処理を並行処理(※)するためのもの。 • 優先度によってどのタスクを実行するか制御される。 • より高優先度のタスクが実行される。 • OS の制御によりタスクが実行される(ディスパッチと呼ぶ)。
- 3. 並行/並列 並行処理: 1つのCPU上で複数タスクが動作すること 並列処理: 複数のCPU上で複数タスクが同時に動作すること 一般的な定義は無いので、ここでは以下のように定義する。 タスクA タスクB タスクC タスクA タスクB タスクC タスクA タスクA タスクA
- 4. タスク状態遷移 • タスクは複数の状態がある • READY <=> RUNNING は OS によって遷移される • RUNNING => WAITING => READY は タスクがみずから状 態遷移させる • RUNNING => DORMANT も然り
- 7. タスクエントリーに注意 • OS がディスパッチするとタスクエントリーが呼ばれる。 • READY→RUNNING と状態遷移する • タスクエントリー内では(長時間)CPUを占有するようなことを してはいけない • for(;;){ レジスタ読んで確認 } のようなことをしてはいけない。 • 他のタスクが CPU を使えなくなる。 • 迅速に処理しとっとと終了すべし
- 9. タスク優先度に注意 • ハードウェアに近いタスクほど高優先度 • そうでないタスクが低優先度 • システム全体を考慮して優先度が決定されるので、勝手に優先 度を設定しないこと。
- 11. スタックサイズに注意 • スタックサイズはタスクが利用できるメモリ • 自動変数や関数呼び出しの引数を記憶したりする • 大きすぎる自動変数(配列とか)を作ったり、関数呼び出しが深 すぎるとスタックオーバーフローする • 原因調査しづらい非常に厄介な現象となるので注意
