Important locations:
- FACET elog: http://physics-elog.slac.stanford.edu/facetelog/
- Important nodes: "rhel6-64.slac.stanford.edu" (general login node) "mcclogin" (node to reach the control servers) "facet-srv01" (control server)
- Data storage:
/nfs/slac/g/facetdata/nas/nas-li20-pm00 (accessible from, e.g., mcclogin)
Example data analysis procedure:
- Go to the FACET elog: http://physics-elog.slac.stanford.edu/facetelog/
- Find the shift summary with information about the data sets taken, e.g., http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2021/32/13.08&pos=2021-08-13T06:00:00
- Determine which run we want to analyze, e.g., http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2021/32/13.08&pos=2021-08-13T04:50:00
- (Log into facet-srv20 (you need permission, see FACET Computing): ssh fphysics@facet-srv20 -Y): only needed if the data analysis should be done on the cluster
- Log into a general SLAC computing note from your own computer, e.g., ssh smeuren@rhel6-64.slac.stanford.edu
- Get your personal home folder via pwd, e.g., /afs/slac.stanford.edu/u/gu/smeuren
- Log into mcclogin, e.g., ssh smeuren@mcclogin -Y
- smeuren@mcclogin $ scp -r fphysics@facet-srv20:/nas/nas-li20-pm00/E305/2021/20210813/E305_00292 /afs/slac/u/gu/smeuren/
Nodes with access to the internet:
- Log into mcclogin, e.g., ssh smeuren@mcclogin -Y
- Log into, e.g., ssh smeuren@rhel6-64.slac.stanford.edu -Y
- start firefox (slow due to x-forwarding)
Read the metadata (matlab) files from python
- Get access to python (e.g., on facet-srv01): source $PACKAGE_TOP/anaconda/envs/python3.7env/bin/activate On rhel: source /afs/slac/g/lcls/package/anaconda/envs/python3.7env/bin/activate (one might need to explicitly start a bash shell)
- run python3
