  1. LCLS-II Online S2E Simulation Repository Tim Maxwell, Gabe Marcus, Yuantao Ding, Andrea Chan

  2. Online S2E Simulation Repository • This is: • To sharecurrent design files w/ LCLS-II collaboration • For final, previously presented simulations • With minor support for in-progress design files • To provide organizationfor key simulations • This is not: • For MAD decks (already exists, separate) • For actively exchanging preliminary designs • For archive purposes

  3. Organization: Machine-path approach • Connect simulation combinations as a logical tree, basic path structure: • “Follow the electron,” choose config at each level to proceed through available branches Example: • Possibly overwhelming, but… • Path describes whole machine • No input/output ambiguity • Less redundancy of input files • If one sim. is changed, clear which inherit changes

  4. Repository Permissions • UNIX Web Share • Read Permit:World wide, public read access (all are welcome) • Write Permit: SLAC UNIX acc’t + permit req’d for editors • Management: Use favorite SSH/SCP tools for transfer

  5. UNIX Web Share • Public browser access • http://www.slac.stanford.edu/grp/lcls/lcls-2/ap/sims • UNIX access (acc’t required), SSH/SCP to root path [USER]@flora.slac.stanford.edu:/afs/slac.stanford.edu/www/grp/lcls/lcls-2/ap/sims • Paths structured as

  6. UNIX Web Share • The following will be initially created: • ../sims/SC/Astra_186MHz_300pC_unif/Eleg_2BC_1000A • ../sims/SC/Astra_186MHz_300pC_unif/Eleg_3BC_1000A • ../sims/SC/Astra_186MHz_100pC_unif/Eleg_2BC_1000A • ../sims/SC/Astra_186MHz_100pC_unif/Eleg_3BC_1000A • ../sims/SC/Astra_186MHz_20pC_unif/Eleg_2BC_750A • ../sims/SC/Astra_186MHz_20pC_unif/Eleg_3BC_750A • ../sims/NC/Astra_150pC_unif/Eleg_3000A_13p6GeV • ../sims/NC/Astra_150pC_unif/Eleg_1200A_4p3GeV • ../sims/NC/Astra_20pC_unif/Eleg_3000A_13p6GeV • Each of these will have final undulator subfolders: ../Gene_HXR_SASE ../Gene_HXR_SS ../Gene_SXR_SASE ../Gene_SXR_SS

  7. UNIX Web Share • Within /simsthere is also /support for global support files • ../sims/support/Astra • ../sims/support/Elegant • ../sims/support/Genesis • Notes and links to the software used throughout are posted here and any custom files (e.g., wake files)

  8. UNIX Web Share • Limited ../sims/scratch/ space available • For sharing near-complete or proposed designs • Must have SLAC UNIX account, then contact tmaxwell@slac.stanford.edu • Creates path ../sims/scratch/[YOURUSERNAME] • Write access only to owner • Note: Scratch is still world-wide, public read access

  9. UNIX Web Share • Guidelines: • Contact/editor will be posted for each simulation • Upload reviewed results and revisions • Answer questions about files • Decks and outputs all in one path • e.g.: /SC/Astra_186MHz_300pC_unif/Eleg_2BC_1000A/. • Only contains Elegant files • Subfolders reserved for subsequent Genesis simulations • Scratch space is not for use as a “Dropbox” • Out of date designs will be removed (no archiving)
