UBNUTU 설정

Rstuio Server사용여부 및 Sigle-user multi-user여부에 따라 설정해야 하는 것이 달라진다.

CUDA 라이브러리 설치과정에서
CUDA binaries경로를 PATH 와 LD_LIBRARY_PATH에추가
CUDA_HOME 환경변수를 설정

$ echo $CUDA_HOME
$ echo $LD_LIBRARY_PATH

LD_LIBRARY_PATH수정

sudo vi /etc/rstudio/rserver.conf

rsession-ld-library-path=/usr/local/cuda/lib64

CUDA_HOME 과 PATH 변수 설정

vi /usr/lib/R/etc/Rprofile.site

Sys.setenv(CUDA_HOME=”/usr/local/cuda”)
Sys.setenv(PATH=paste(Sys.getenv(“PATH”), “/usr/local/cuda/bin”, sep=”:”))
