GPU計算入門 with OpenCL 張安邦
注意 •指標！ •手動記憶體管理！！
whoami • 張安邦 • C++ developer • 3年OpenCL經驗 • 中山大學宿舍網路推廣會會長
CPU •一行一行執行
平行計算 • 迴圈內有非常多的計算 • 迴圈要跑很多次 • 寫一次迴圈內的計算 • 不同核心跑不同次迴圈的計算
GPU •大量核心 •高記憶體頻寬 •幾乎隨手可得
OpenCL •由多家廠商聯合推出的運算API •開放標準 •AMD/NVIDIA/Intel/etc...
運作流程 1. ???? 2. profit
運作流程 1. 決定要在哪裡執行 2. 透過OpenCL建立執行程式 3. 準備資料 4. run 5. 拿回運算結果
OpenCL C •跑在GPU上面 •高性能 •特殊關鍵字
開始寫code吧 • C++ •但是你可以用任何語言
查詢有什麼廠商的裝置可以用
找有什麼裝置可以用
載入原始檔並編譯
準備記憶體並分配資料
執行程式
取得結果
BTW •現在Raspberry Pi也有支援OpenCL •VC4CL(去GitHub找)

Sitcon2018-Intro to GPU computing with OpenCL

Editor's Notes

  • #6 It works well untill this happens
  • #7 execute different task on different cores
  • #9 Also introduce WebCL and hanguage bindings here Also the C API
  • #12 介紹OpenCL Platform/Device架構 1. 多Platform(aka 廠商) 2. 一個platform下可能有多個device 3.Device有自己的Memory
  • #13 Memory Model May not explain local memory
  • #14 介紹OpenCL C與各種關鍵字
  • #16 介紹OpenCL Platform/Device架構 1. 多Platform(aka 廠商) 2. 一個platform下可能有多個device 3.Device有自己的Memory
  • #20 Memory Model May not explain local memory
