deep_md_test

Deepmd integration with Paddle, without lammps

  • Used Paddle commit c91aaced74aa1a34c8bde2e53b3072baf8012e73 and compile with MKLDNN ON to generate paddle_inference_install_dir and
export PADDLE_ROOT=/xxx/Paddle/build/paddle_inference_install_dir
  • Compile paddle-deepmd and generate DEEPMD_ROOT by
git clone https://github.com/X4Science/paddle-deepmd.git
rm -rf /home/danqing/deepmdroot/ && mkdir /home/danqing/deepmdroot && DEEPMD_ROOT=/home/danqing/deepmdroot(or add in bashrc with export)
cd /home/danqing/repo/paddle-deepmd/source && rm -rf build && mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=$DEEPMD_ROOT -DPADDLE_ROOT=$PADDLE_ROOT -DUSE_CUDA_TOOLKIT=FALSE -DFLOAT_PREC=low ..
make -j 4 && make install
make lammps
  • Compile deep_md_test and run
bash run.sh
./infer_test
  • The results are as follows

  • The above results shows succesful inference with double64. We then need to enable mkldnn fp32 inference for deep_md Just change
void PrepareTRTConfig(Config *config) {
  config->SetModel(FLAGS_dirname + "/model.pdmodel", FLAGS_dirname + "/model.pdiparams");
  //config->EnableUseGpu(100, 0);
  //Uncomment for CPU Backend
  config->DisableGpu();
