SDV nodes

• deeper-sdv cluster nodes (Haswell) have been taken offline: deeper-sdv[01-16]
  • not included in SLURM anymore
  • deeper-sdv[09-10] used for testing (please contact j.kreutz(at)fz-juelich.de if you would like to get access

• knl01: serves as golden client for imaging only

• dp-sdv-esb[01,02]: will only be powered on demand

Software issues

Cuda and Rocky 8.6

• New CUDA drivers on the compute nodes.In case of problems, please manually prepend your LD_LIBRARY_PATH (first for libcuda, second for libcublas, fft, etc.):

  ln -s /usr/lib64/libcuda.so.1 .
  ln -s /usr/lib64/libnvidia-ml.so.1 .
  LD_LIBRARY_PATH=.:/usr/local/cuda/lib64:$LD_LIBRARY_PATH srun <srun_args> <exe> <exe_args>
  

nvidia profiling tools

• to launch the tools on a compute node using X-Forwarding another SSH session is needed:

srun --forward-x -p dp-esb -N 1 -n 1 --pty /bin/bash -i
ssh -X -J <your account>@deep.zam.kfa-juelich.de <your account>@<the node you received>

• you will still see a warning "OpenGL Version check failed. Falling back to Mesa software rendering.", but the profling tool (e.g. nsight-sys) should start up
