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
- Build performance model:
/*
* rankfile is for process binding * appfile tells what processes will execute */
$ mpirun -rf rankfile -app appfile_fpm
