| 13 | h2. Summer 2019 Run Info |
||
| 14 | 2 | Stephen Kay | |
| 15 | The Summer 2019 data was stored alongside the earlier KaonLT data. The data can be found in - |
||
| 16 | |||
| 17 | * /mss/hallc/spring17/raw/ - Raw data for 2019 PionLT run |
||
| 18 | * /mss/hallc/kaonlt/ - Analysed data |
||
| 19 | * /volatile/hallc/c-kaonlt/ - Temporary analysed data |
||
| 20 | |||
| 21 | Access to these directories is via the "c-comm2017" group |

| 23 | h2. 2021 Run Info |
||
| 24 | |||
| 25 | For the 2021 PionLT run, a new group was created, along with numerous new directories - |
||
| 26 | |||
| 27 | * New unix group: 'c-pionlt' |
||
| 28 | * New Farm/Auger project: c-pionlt |
||
| 29 | ** Use this Project name for simulation (and later analysis) jobs on the Farm |
||
| 30 | |||
| 31 | * Disk resources: |
||
| 32 | ** /volatile/c-pionlt/ - directory, 6 TB high quota; 2 TB Guarantee |
||
| 33 | ** /group/c-pionlt/ - directory (100GB quota) |
||
| 34 | *** snapshotted hourly; backed up automatically, use for analysis scripts, etc. |
||
| 35 | ** /work/hallc/c-pionlt/ - directory (1TB quota) |
||
| 36 | *** NOT backed up in any way |
||
| 37 | *** Has some small-file / performance benefits (but this doesn't really apply to hcana/podd analysis) |
||
| 38 | *** Not super useful in a modern workflow (mostly historical), butnit's there if you want it. |
||
| 39 | *** Not intended for rootfile output or to store extra copies of CODA files, etc. |
||
| 40 | *** Good for large source code bases (that are 'backed up' on an external git repo, for example) |
||
| 41 | *** OK for modestly sized simulation output perhaps, though /volatile is still best. |
||
| 42 | ** New Tape/disk allocations: |
||
| 43 | *** /mss/hallc/c-pionlt/raw - tape volume for raw data output |
||
| 44 | *** /mss/hallc/c-pionlt/analysis - tape volume for analysis output |
