qiime2 2024.10: slow alpha rarefaction

Hi everyone,

I’m having an issue with qiime diversity alpha-rarefaction. I ran the same command on both my local machine and a slurm cluster. The job took only about 1.5 hours to finish on my local machine, while it took over 9 hours on slurm. I use qiime2 version 2024.10

I allocated generous resources to the slurm job, so I don’t think it is a resource limitation. I’m wondering if there could be other factors causing this significant difference in runtime.

Does anyone have any ideas about what might be causing this? Thanks in advance for any suggestions.
