gpu 服务器基本信息(单台信息):

  • CPU: Intel(R) Xeon(R) Silver 4310 CPU @ 2.10GHz (双路共48线程)
  • RAM: 64G
  • GPU: A100-PCIE-40GB ---- CUDA Version: 11.2
命令行输入 nvidia-smi 查看当前gpu状态

服务器环境信息:

  • gpu1 和 gpu2 均已安装cvmfs
  • gpu1 已安装可使用gpu版本的root(6.28.10),登录后会自动调用环境。 ⚠️ conda和cvmfs调用的root均不支持gpu。
在root中使用gpu:
  • 拟合: 保持程序其余部分不变,将 pdf.fitTo(data); 修改为 pdf.fitTo(data, BatchMode ("cuda")); 即可实现。 可参考 /usr/share/tutorial/gpu/rf_gpu_basics.C (gpu1)
  • tmva: 仅DL
