 +The steps above can also be done for the default cuda installation on exx96 where the soft link ''/usr/local/bin/cuda'' would have pointed to ''/usr/local/bin/cuda-10.2''. Do not follow the soft link and use the path with the toolkit version in it when setting your cuda environment.
  
 Next test is to see if older software runs compatible with newer drivers. We test that by running a gpu program against new 550 driver and cuda toolkit 9.2 and see if it works (~hmeij/slurm/run.centos7.2). Next test is to see if older software runs compatible with newer drivers.
