Running event generation on cluster mode fails

Asked by Jay Sandesara on 2020-06-21

I am trying to generate events using the cluster mode. However it keeps failing. The same process runs fine on multicore mode. I am copying the error and configuration from debug:

Can you unset those three parameters?
          cluster_temp_path : /scratch/jsandesara/run (user set)
             cluster_memory : /scratch/jsandesara/run (user set)
          cluster_local_path : /scratch/jsandesara/run (user set)

After that, each cluster is different, so might need to customize the cluster class to fit the requirement imposed by your sys-admin.
I do not have any SGE cluster to try, that implementation is more than 10 years old, so it might also not work with the latest SGE version.
