 AI 筆記 NVDIA AMD 以及 ? Intel ? 整理一些收集來的筆記： CUDA and OpenCL are the two main ways for programming GPUs. CUDA is by far the most developed, has the most extensive ecosystem, and is the most robustly supported by deep learning libraries. CUDA is a proprietary language created by Nvidia, so it can’t be used by GPUs from other companies. When fast.ai recommends Nvidia GPUs, it is not out of any special affinity or loyalty to Nvidia on our part, but that this is by far the best option for deep learning. Nvidia dominates the market for GPUs, with the next closest competitor being the company AMD . This summer, AMD announced the release of a platform called ROCm to provide more support for deep learning. The status of ROCm for major deep learning libraries such as PyTorch, TensorFlow, MxNet, and CNTK is still under development.  總之Nvidia 系列就要研究CUDA 而如果是其他就要靠OpenCL OpenCL （Open Computing Language，开放计算语言） 是一個為異構平台編寫程式的框架，此異構平台可由CPU、GPU、DSP、FPGA或其他類型的處理器與硬體加速器...

如何使用MTK MCS Lite 連結 QNAP NAS 2021/2/17/更新： MCS要終止服務了。來嘗試在QNAP NAS上重新建立服務吧 步驟一：下載Source code上傳至NAS: (1)從MCS-lite github上面下載source code: https://github.com/MCS-Lite/mcs-lite-app/releases (2)上傳檔案至NAS上(可自訂目錄，這裡以Web資料夾為範例) (3)解壓縮 步驟二：建立Container (1)開啟 Container Station(如果沒有請至AppCenter安裝) (2)建立node.js build container (3)將共用資料夾新增我們剛剛上傳MCS-lite到NAS上共用資料夾的路徑 EX:/web (4)建立完成後選擇我們剛剛建立的Container，點選終端機，輸入bash後按確認 (5)執行指令: cd /web/mcs-lite-app-1.0.4 cd client && npm install && npm run build:global cd .. npm install exit (6)建置完成後可將node-1 Container移除 步驟三：建立MCS-Lite Container (1)重新建立一個新的Node.js Container (2)命令填入:node /mcs/server.js (3)port轉發規則(如果port與其他軟體有相衝突請自行變更): 主機 容器 通訊協定 3000 3000 TCP 8000 8000 TCP 1935 1935 TCP 8888 8888 TCP (4)共用資料夾掛載我們剛剛存放Source code的資料夾 注意:掛載路徑必須要/mcs( 如要更改路徑(2)的命令也必須更改) (5)建立完成後就可以開啟網頁開始使用Mcs-Lite(http://X.X.X.X:3000) 更多IoT 應用分享： 使用家用閘道器連結QNAP IoT Suite和QV...

簡介在自動控制領域的PLC技術和PC-based技術 台北自動化展： PLC可以是下列意思： 可程式邏輯控制器 （Programmable Logic Controller），一種具有微處理器的數位邏輯控制器，用於自動化控制。 電力線通信 （Power Line Communication），信息工程學中，在傳送電力的電線上同時傳送的信息。 在此我們主要是要介紹： 可程式邏輯控制器 （Programmable Logic Controller） PLC技術和PC-based技術是當前比較具有代表性的控制技術， 兩者的技術起源和發展有較大的差異。 PLC(Programmable Logic Controller)產生於上世紀70年代初。 最早的PLC是以替換繼電器系統的角色出現， 其主要實現的功能僅僅是邏輯簡單的順序控制功能。 PLC一經出現， 就以其高可靠性、小體積和直觀的程式設計模式而顯示出強大的生命力， 成為自動控制領域的“明星”。 PC-based是一種基於PC技術的控制系統。 最早的PC-based控制系統是以工控機為核心， 通過擴展帶PCI介面的專用板卡組成。 PC-based借助於IT技術的發展，在運算、存儲、 組網和軟體開放性方面具有優勢。 PLC和PC-based兩者在技術特點上存在明顯區別。 PLC具有體積小、功耗低、抗幹擾能力強； 具有很高的可靠性，其平均無故障率時間間隔（MTBF）可達50萬、 甚至100萬個小時；具有簡單直觀的程式設計模式(如梯形圖)； 具有內部即時時鐘。 而PC-based具有大運算能力； 具有開放標準的系統平臺和PCI介面；精美且低成本的顯示技術； 豐富的組網能力。 但系統的可靠性略差， 如性能較好的IPC的平均無故障時間間隔約5萬小時。 此外，PC-based雖然具有很強的CPU， 但其多工作業系統是非即時的， 所以程式的迴圈週期反而沒有高性能的PLC快。 PLC更適合於設備控制，而PC-based更多地用於設備運行狀態的監視。 相對於PC-based而言，PLC具有配置靈活、體積小、適應惡劣環境、 抗幹擾性強、可靠性高等優點 ...

本文將介紹如何在QNAP NAS 安裝openHAB 這一個開源軟體來控制各種物聯網裝置 (測試環境 QTS 版本： 4.3.3 0154 測試NAS：TS-251A) openHAB官方網站：  http://www.openhab.org/ 以下是openHAB教學影片： 介紹： 而在QNAP NAS上該要怎麼設定？以下分三步驟 Step1: QNAP NAS & Z-Wave USB dongle 插入Z-Wave的USB之後 用ssh連到NAS 輸入以下指令 "insmod /usr/local/modules/cdc-acm.ko ” "chmod 777 /dev/ttyACM * " Step2: Install openHAB 兩種方法: 用Container Station UI建立或是連SSH進NAS輸入指令建立 (方法1  用Container Station UI建立 ) (方法2  連SSH進NAS輸入指令建立 ) SSH輸入 docker run \         --name  openhab -zwave2 \ -p 18080:8080 \ -p 8443:8443 \ -p 5555:5555 \ --privileged \ openhab / openhab :2.1.0- snapshot-amd64 Step3: Setup openHAB 如果/dev/ttyACM0無法連線的話， SSH連進NAS輸入 ls -al /dev/ttyACM*看看是哪個port 點選藍色圈圈可以加入功能到Control 面板中 注意事項： 1. 每次重新開機都要打Step1那兩行 "insmod /usr/local/modules/cdc-acm.ko ” "chmod 777 /dev/ttyACM * " 2.  /dev/ttyACM0可能會跑掉 需輸入 ls -al /dev/ttyACM*看看在哪一個port 在設定中更換 ...
