How to register workers for a cluster install

Hi, I installed cryo2_master on the head node of our cluster and installed cryo2_worker on a node with GPU card. I’m able to start the master and access its interface via a webbrowser. However, for cluster setup, how do I register workers? I already used the command “cryosparcm cluster example slurm” to generate the cluster_info.json and files. What is the next step?

Hi @jw24,

Please see our installation guide for more information on how to connect a cluster:

Hi Stephan, I was in that page before but it is for standalone worker. Plus, it requires to specify the worker hostname but it is unknown before the slurm job manager dispatches the jobs. Can you be more specific?

Hi @jw24,

Please click on the “Connect a Cluster” tab.

It did not say how to register the cluster. I already generated and edited the cluster_info.json and files. I’m still at lost. What should be the command to “register the cluster” or “connect workers to the master”?

I’m facing the same issue. I registered the cluster using the cluster script and cluster info files but I still get this error
