Using Fupermod on hybrid multicore/GPUs node

  • Compiling : Create two separate directories for configuration with selected CPU cblas (e.g. gsl, acml, mkl)and GPU cblas (e.g. cublas).
    • For example: Using acml blas for CPU and cublas for GPU computing
cd fupermod/
mkdir acml_config 
cd acml_config
./configure --with-cblas=acml
mkdir cuda_config 
cd cuda_config
./configure --with-cblas=cuda
  • Building performance model:
    • rankfile is for processing binding, appfile tell mpi what programs to launch
 $ mpirun -rf rankfile -app appfile_fpm
