 You also need to use ''qsub -q gpu.q@dll[256]'' because only those machines have drivers which support CUDA 9. You also need to use ''qsub -q gpu.q@dll[256]'' because only those machines have drivers which support CUDA 9.

 +**Testing configuration (so far on twister2 only)**
 +
 +Multiple versions of ''cuda'' and ''cudnn'' can be accessed in ''/opt''.
 +System default version for both libraries is configured in ''/etc/ld.so.conf.d/cuda.conf'' as:
 +
 +  /opt/cuda/lib64
 +  /opt/cuda/extras/CUPTI/lib64
 +  /opt/cudnn/lib64
 +
 +Actual version used depends on the link in ''/opt''. For example:
 +
 +  ls -l /opt
 +  ...
 +  lrwxrwxrwx 1 root root  8 dub  9 12:30 cuda -> cuda-9.0
 +  lrwxrwxrwx 1 root root  9 dub  9 12:32 cudnn -> cudnn-7.1
 +  ...
 +  
 +This means that the system is using ''cuda 9.0'' and ''cudnn 7.1''.
 +
 +If system default version does not work for you, you can set library path from your ''~/.bashrc''.
