Display a list of available GPUs

$ nvidia-smi -L

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, and appfile tells mpi what programs to launch

 $ mpirun -rf rankfile -app appfile_fpm

 example of a rankfile:
 rank 0=ig.icl.utk.edu slot=0:0
 rank 1=ig.icl.utk.edu slot=0:1
