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: configuring with acml for CPU and cublas for GPU
$ cd fupermod/
$ mkdir acml_config $ cd acml_config $ ../configure --with-blas=acml $ make
$ mkdir cuda_config $ cd cuda_config $ ../configure --with-blas=cuda $ make
- Building performance model:
- Rankfile is for process binding, and appfile tells mpirun 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 ...
- Example of an appfile for building functional permanence model (appfile_fpm):
# GPU # e.g. Linking against cublas, and fupermod is configured under cublas_config # suboption g=0 means device 0 is selected for computing -host localhost -np 1 $HOME/fupermod/cublas_config/tools/builder -l $HOME/fupermod/cublas_config/routines/mxm/.libs/libmxm_1d.so -o k=640,g=0 -U10000 -s10 # CPU # e.g. Linking against acml, and fupermod is configured under acml_config -host localhost -np 47 $HOME/fupermod/acml_config/tools/builder -l $HOME/fupermod/acml_config/routines/mxm/.libs/libmxm_1d.so -o k=640 -U10000 -s10
- Data partitioning
- Matrix size D = N x N, and machinefile lists the nodes participating in the computing
$ fupermod/tools/partitioner -l fupermod/routines/mxm/.libs/libmxm_1d.so -D10000 -o N=100 -m machinefile
- Running matrix multiplication
$ mpirun -rf rankfile -app appfile_mxm
- Example of an appfile for matrix multiplication (appfile_mxm)
# GPU # Assuming fupermod is configured under cublas_config, linking against cublas # -g0 means device 0 is selected for computing -host localhost -np 1 $HOME/fupermod/cublas_config/routines/mxm/mxm_2d -k640 -g0 -m machinefile # CPU # Assuming fupermod is configured under acml_config, linking against acml -host localhost -np 47 $HOME/fupermod/acml_config/routines/mxm/mxm_2d -k640 -m machinefile
