Problem: Error message “ssh: Could not resolve hostname gipdeep: Name or service not known”.
Solution: Occurs mainly when connecting from outside the campus. Make sure the VPN is connected and try to SSH to instead.

Problem: Error message “Remote side unexpectedly closed network connection” when trying to upload or download files to or from the server.
Solution: SSH sessions limit is 10. Close other connections and try again.

Problem: Job pending.
Solution: Resource over-scheduling (for the pending job) or cluster load. See the Workload management and Job and resource limits sections.

Problem: Error message “Could not load dynamic library ‘*’”
Solution: If you receive this error on gipdeep(the login server) – launch the script on a node using Slurm. gipdeep is a virtual server, has no GPUs and doesn’t have CUDA installed.
If you receive the error on a node:
Add these lines at the end of the .bashrc file in your home folder (~/.bashrc):
export PATH=”/usr/local/cuda/bin:$PATH”
export LD_LIBRARY_PATH=”/usr/local/cuda/lib64:$LD_LIBRARY_PATH”
Save the file, exit the session (or job) and reconnect. Start bash on a node:
srun –pty /bin/bash
and run this command
nvcc -V
You should get CUDA’s version details.
