Cryosparc Cluster Installation

Hi all,

Over the weekend, I have been trying to get cryosparc to work well with our local cluster. Right now, my jobs are submitted via the login node and nothing happens after that.

Cluster nodes have a separate worker folder and they are using cuda 10.2

Here is the current configuration:

{
    "name": "nogales",
    "title": "nogales",
    "worker_bin_path": "/cryosparc/worker/cryosparc_cluster/cryosparc_worker/bin",
    "send_cmd_tpl": "ssh whale {{ command }}",
    "qsub_cmd_tpl": "sbatch {{ script_path_abs }}",
    "qstat_cmd_tpl": "squeue -j {{ cluster_job_id }}",
    "qdel_cmd_tpl": "scancel {{ cluster_job_id }}",
    "qinfo_cmd_tpl": "sinfo",
    "cache_path": "/volatile/cryosparc",
    "cache_quota_mb": null,
    "cache_reserve_mb": 10000
}

#!/usr/bin/env bash
#### cryoSPARC cluster submission script template for SLURM
## Available variables:
## {{ run_cmd }}            - the complete command string to run the job
## {{ num_cpu }}            - the number of CPUs needed
## {{ num_gpu }}            - the number of GPUs needed. 
##                            Note: the code will use this many GPUs starting from dev id 0
##                                  the cluster scheduler or this script have the responsibility
##                                  of setting CUDA_VISIBLE_DEVICES so that the job code ends up
##                                  using the correct cluster-allocated GPUs.
## {{ ram_gb }}             - the amount of RAM needed in GB
## {{ job_dir_abs }}        - absolute path to the job directory
## {{ project_dir_abs }}    - absolute path to the project dir
## {{ job_log_path_abs }}   - absolute path to the log file for the job
## {{ worker_bin_path }}    - absolute path to the cryosparc worker command
## {{ run_args }}           - arguments to be passed to cryosparcw run
## {{ project_uid }}        - uid of the project
## {{ job_uid }}            - uid of the job
## {{ job_creator }}        - name of the user that created the job (may contain spaces)
## {{ cryosparc_username }} - cryosparc username of the user that created the job (usually an email)
##
## What follows is a simple SLURM script:

#SBATCH --job-name cryosparc_{{ project_uid }}_{{ job_uid }}
#SBATCH -n {{ num_cpu }}
#SBATCH --gres=gpu:{{ num_gpu }}
#SBATCH -p gpu
#SBATCH --mem={{ (ram_gb*1000)|int }}MB             
#SBATCH -o {{ job_dir_abs }}
#SBATCH -e {{ job_dir_abs }}

available_devs=""
for devidx in $(seq 0 15);
do
    if [[ -z $(nvidia-smi -i $devidx --query-compute-apps=pid --format=csv,noheader) ]] ; then
        if [[ -z "$available_devs" ]] ; then
            available_devs=$devidx
        else
            available_devs=$available_devs,$devidx
        fi
    fi
done
export CUDA_VISIBLE_DEVICES=$available_devs

srun {{ run_cmd }}

Here is the actual submit script that’s generated and the corresponding error.

I’d appreciate any pointers to this. Once I am back home today, I will try manually submitting the script as cryosparc user and see what’s going on.

Thanks!
