1. Overview of Broadband Platform Software as used in SWUS Project

2. SCEC Software Activities on BBP SCEC software responsibilities on project include: 1.Integration of scientific methods into Broadband Platform Added Irikura, Composite Source Model, EXSIM in 2013 Added multiple Part A and Part B reports Added GMPE codes and utilities (e.g. rotD50, pynga) 2.Running BBP simulations using SCEC computing resources and posting simulation results Ran full Part A and Part B (BBP v13.5) for most methods Ran portions of Part A and Part B (BBP v13.6) for most methods

3. Define the BBP Platform The SCEC BBP Platform (BBP) integrates: scientific software (e.g. C and Fortran) formatting scripts (e.g. python) seismic software utilities (e.g. rotd50, pynga) post-processing plotting routines observational data (e.g. seismograms) expected results (e.g. seismograms, Peak SA values)

4. Standard BBP Inputs and Outputs Standard Inputs: Earthquake Source File (.src file) Station List (.stl file) Velocity model specification (region) Computational Method Each method has region specific input files (e.g. Greens functions) Standard outputs: Velocity seismograms Acceleration seismograms Standard Rupture Format (4 methods), Metadata list of programs and input files used Metadata compute environment information

7. BBP Software Version Strategy As a general principle, the newest version of the broadband platform is better than any previous version and users should upgrade at first opportunity. Older versions of the code will be archived to support reproducibility of previously obtained results. Any use of an older version of the platform should be examined carefully to understand the scientific goals of using an older version.

8. Versioning BBP Results BBP results should be attributed to specific BBP software and configuration versions because results may change as methods improve. For a Part A Validation Result, changes to any of these three versions that may impact the results: Broadband Version13.6.0-30-May-2013 -This is the source code version Velocity model versionLABasin - 29-May-2013-1.07 -This is the region specific input parameters used in the simulation Validation package versionNR - 29-May-2013-1.05 - This is the set of observational data and associated corrections used in the GOF plots for this validation simulation These are found in the index.html file in the outdata directory for each simulation.

9. Comparing Results Between BBP Software Versions When comparing BBP results, all results should be produced with the same version of the broadband platform. Standard problems should be re-run when new versions of the platform are released. We assume that: Post processing changes affect results for all methods. Changes to any method’s source code, including python wrappers, may affect results from other methods Changes to one method parameters do not affect results from another method We make this assumption to simplify our analysis of results: We do not have the resources to detect all possible sources of coupling between scientific programs in broadband platform This assumption can be relaxed, if additional analysis is done to confirm results are equivalent between BBP software releases.

10. Results From Two Software Versions We have posted results. These should be considered results from BBP v13.6.0 Results are posted under two studies: http://bbpvault.usc.edu/bbp/BBP_June2013_Study/ http://bbpvault.usc.edu/bbp/BBP_May2013_Study/ When accessing these results: Use v13.6 results for any simulation if the results exist. If no v13.6 results exist, use v13.5 results. If no v13.5 results exist, simulation was not completed.

In each simulation directory, a simulation specification file (sim_id.xml) provides detailed information about the programs run to produce the results in the directory.
