||
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 |
