Under Construction (Not for Users)

The S3DF (SLAC Shared Science Data Facility) is a SLAC-wide computing facility. For LCLS the S3DF will replace the PCDS current computer and storage resources used for data processing.  

The S3DF has it's own users home directories.

Accessing the S3SDF

To access to the S3DF systems  connect to the s3dflogin pool and login with you unix account:

% ssh sdf3login.slac.stanford.edu 

The login nodes don't have the data folders mounted. Eventually there will be LCLS specific interactive nodes. For data transfers the sdfdtn001 - sdfdtn005 are provided. 

Setup in S3DF

The group folder for the data-systems is:

/sdf/group/lcls/ds

it contains many subfolders for software and releases (sw), detector calibration (detector) and more. The above prefix corresponds to the /cds/group/psdm in PCDS.

All LCSL data are below:

/sdf/data/lcls/ds/<instr>/<expt>/<expt-folders>

Using psana in SDF

psana1

% source /sdf/group/lcls/ds/sw/ana/conda1/manage/bin/psconda.sh  [-py2]

The default (no -py2) uses python3.

psana2

% source /sdf/group/lcls/ds/sw/ana/conda2/manage/bin/psconda.sh
