The page https://slurm.schedmd.com/heterogeneous_jobs.html says to use #SBATCH hetjob but in 18.04 (Debian 10 packages) I had to use #SBATCH packjob Strangely (?) it appears to recognize hetjob line, but as no-op. IIUC, it got changed from packjob to hetjob after 18.08 . To avoid confused users, it could be better to cite the older syntax in the docks and keep recognizing it in newer ones (maybe emitting a warning). Hope it helps improve an already great product!
