| Attachments: | Ignore empty slots on XC service blades | ||
Hey Kevin - Thanks for the submission, but unfortunately since the XC series is EOL I don't have a good contact at Cray/HPE to validate this type of change - they've all shifted their focus to Shasta - and I'm quite hesitant to roll it out globally on the chance that it could cause issues. You're certainly welcome to keep using this as a site local patch though. cheers, - Tim |

Found 13 service nodes. Gathering hardware inventory... Found 19 compute nodes. Compacting node configuration... Compacted into 5 group(s). Writing Slurm configuration to /root/20200501/slurm-20.02.1/slurm.conf... Writing gres configuration to /root/20200501/slurm-20.02.1/gres.conf... Done when there are clearly only SEVEN service nodes, not 13. The attached patch if cname: - service.append(cname.group(1)) + empty = re.search( + r'\|\s+empty\s+\[', + line) + if empty is None: + service.append(cname.group(1)) ignores empty slots on the service blades and so returns the correct number of service nodes, vis: <slurm_source>/contribs/cray/csm/slurmconfgen_smw_kmb.py -t $SLURM_DIR/contribs/cray/csm/ -o $SLURM_CONF_DIR \ sdb p0 Getting list of service nodes... Found 7 service nodes. Gathering hardware inventory... Found 19 compute nodes. Compacting node configuration... You might want to run this one past someone at Cray, just in case they really do want to "configure" those empty slots. BTW, this was run on our Test&Dev system, hence the small number statistics.
