Raspberry Pi OS 64-bit 與 32-bit 的效能差異
Raspberry Pi OS 64-bit 與 32-bit 的效能差異
前幾天提過「Raspberry Pi OS 64-bit 版本正式推出」，而 Phoronix 實際拿正式版測試 64-bit 與 32-bit 的系統差異了，在「Raspberry Pi OS 32-bit vs. 64-bit Performance」這邊可以看到每一個測試項目的結果。 測試的硬體是 Raspberry Pi 400，這台機器基本上就是 4GB 版本的 Raspberry Pi 4 加上週邊配件： Using a Raspberry Pi 400 keyboard computer with 4GB of RAM, I ran some fresh benchmarks of Raspberry Pi OS in its default 32-bit build and then again with the new 64-bit build. 先講結果，在…

Graylog syslog server on Raspberry Pi 4 (8gb)
This is how I installed graylog on my Pi.
What is needed:
1.- Raspberry Pi 4 - 8 GB Ram with firmware patch to boot from USB.
2.- Geekworm Raspberry Pi 4 mSATA SSD Adapter X857.
3.- MSata drive (using a 250 gb drive).
4.- Raspbian/Debian, Ubuntu aarch64.
5.- Network connection (Ethernet, WiFi and BT disabled).
6.- Rpi4 heatsinks (optional/recommended).
Procedure:
Install OS (Raspbian Aarch64) on the MSata drive, boot the raspberry pi and then do
# sudo apt update && apt full-upgrade -y
# sudo apt install apt-transport-https openjdk-11-jre-headless uuid-runtime pwgen dirmngr gnupg wget zip curl
Install MongoDB
# curl -s https://www.mongodb.org/static/pgp/server-4.2.asc | sudo apt-key add -
# echo "deb [ arch=arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list
# sudo apt update && sudo apt install mongodb-org -y
# sudo systemctl enable mongod
# sudo systemctl start mongod
# sudo systemctl status mongod
Install Elasticsearch
# wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
# echo "deb [ arch=arm64 ] https://artifacts.elastic.co/packages/oss-7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list
# sudo apt update && sudo apt install elasticsearch-oss -y
# sudo tee -a /etc/elasticsearch/elasticsearch.yml > /dev/null <<EOT cluster.name: graylog network.host: 127.0.0.1 http.port: 9200 action.auto_create_index: false EOT
# sudo systemctl daemon-reload
# sudo systemctl enable elasticsearch.service
# sudo systemctl restart elasticsearch.service
Install Graylog
Download the latest graylog-x.x.x.tgz from https://www.graylog.org/downloads-2 and scp it to your PI or
# cd opt
# wget https://downloads.graylog.org/releases/graylog/graylog-x.x.x.tgz
# sudo tar -xf graylog-x.x.x.tgz
# sudo mv /opt/graylog-x.x.x /opt/graylog
# sudo rm graylog-x.x.x.tgz
# vi /etc/graylog/server/server.conf and configure to your needs
To start the server do:
# cd /opt/graylog/bin
# ./graylogctl start
After the server started go to http://server-ip:9000 and use the user admin with the password previously configured, create an input and that should be all.
To configure password and settings on server.conf please refer to graylog documentation.
高性能 Python 解釋器 PyPy 開始支持 AArch64 架構
PyPy 是一個兼容性強大的 Python 解釋器，幾乎是 CPython 2.7 與 3.6 的直接替代品。由於其集成的 JIT 編譯器，速度很快，為了展示新PyPy 的性能，此次官方公告中也進行了一次速度測試，如上圖所示，在一組基準測試中比較了PyPy 與CPython 的性能，同時對比 x86_64 架構上PyPy 的結果。
圖中顯示了 AArch64（hg id 2417f925ce94）上與 CPython（2.7.15）相比 PyPy 的速度提高，以及 x86_64 Linux 筆記本電腦上最新版本 PyPy 7.1.1 和 CPython 2.7.16 相比的速度。結果顯示在大多數基準測試中，AArch64 上實現的加速與 x86_64 筆記本電腦上實現的加速效果相當。 AArch64 上的 PyPy 相比 CPython 有 0.6x 到 44.9x 的加速，x86_64 上是 0.6x 到 58.9x。
需要注意的是，這裡顯示的結果是在 AWS 的 Graviton A1 機器上測量的，Graviton A1 是虛擬機，因此不適合進行基準測試。此外，此基準套件並不能夠反映平均水平。
下面的圖片比較了在 AArch64 與 x86_64 上實現的加速差距，也就是考察 PyPy 在 AArch64 上性能相比 x86_64 提高多少，它可以粗略地了解新移植版本 PyPy 的能力。
有三種結果：運行速度差不多、運行速度提高 2 倍，以及速度為 x86_64 的 0.5 倍。
官方表示該版本還有許多改進的空間，AArch64 帶有大量的 CPU 寄存器，PyPy 後端是用 x86（32 位變體）編寫的，它的寄存器數量非常少。官方認為可以在機器碼方面進行改進，這可能對 AArch64 的影響大於對 x86_64 的影響。此外 AArch64 後端還有許多缺少的功能，這些功能目前使用昂貴的函數調用實現，而不是內聯原生指令，可以進行改進。

EC2 推出 ARM 架構的機器…
看到 AWS 推出使用 ARM 架構的 EC2 instance 了：「New – EC2 Instances (A1) Powered by Arm-Based AWS Graviton Processors」。
在 Quick Start 頁面有 Ubuntu 18.04 (ARM) 可以選，開起來後操作跟標準的 Ubuntu 差不多… 連進去後 uname -a 可以看到是 aarch64：
ubuntu@ip-172-30-2-207:~$ uname -a Linux ip-172-30-2-207 4.15.0-1028-aws #29+nutmeg8-Ubuntu SMP Tue Nov 20 02:59:41 UTC 2018 aarch64 aarch64 aarch64 GNU/Linux
然後來看硬體規格，從最大台的 a1.4xlarge來看是 16 vCPU +…
