I have a Slurm cluster without GPUs. I’ve installed both master and worker on my headnode, as it is equal to my compute nodes. Now I’m trying to log into host:39000
, and I’m only able to see a progress bar very briefly, then I’m presented with a light blue page, with nothing more. Wasn’t it supposed to be a login page?
By inspecting cryosparcm log command_core
, I see this message being flooded every 5 seconds:
[JSONRPC ERROR 2020-04-29 08:38:32.638243 at get_config_var ]

To install the master, I’ve followed this instructions: https://cryosparc.com/docs/reference/install#master
And to install the worker, I’ve followed this: https://cryosparc.com/docs/reference/install#cluster, but changed the --cudapath <cuda_path>
to --nogpu
. At first, the worker installation gave me an error when compiling some package that was including cuda.h
. A second try returned with success, don’t know why.
Kind regards,
Ian
