标题: GPU加速问题GPU可检测，但是不运行
请教群里的大神，我的GPU是英伟达Quadro K4000，拥有768个CUDA核心，我查询了Gromacs GPU算力是3，应该刚刚达标。为啥跑gromacs时显示detected ，但是non-functional。
我cmake编译的代码如下：
cmake .. -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON -DGMX_GPU=CUDA -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda -DGMX_USE_OPENCL=on -DCMAKE_INSTALL_PREFIX=/usr/local/gromacs

mdrun的log如下：
Command line:
  gmx mdrun -deffnm md_0_1 -v -pin on

GROMACS version: 2021.3
