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
