The current official release of Broadband Platform is v11.2.3. This distribution was posted online on Wednesday, 09 May 2012. This is a "bug-fix" version of the platform that fixes a small number of bugs discovered in v11.2.2 since its release in October 2011. Details of the bugs fixes are provided in the release notes. No new features are introduced in this version of the platform. New Broadband platform users should work with this version of the software, and we recommend current Broadband platform users migrate to this new version whenever possible.

The main steps involved in installing the platform as a local installation on Linux machine include:
 +
# The software can be installed in an account on a Linux computer with at least 4GB of disk storage and C, Fortran, and Python software installed.
 +
# From this Linux computer, start a web browser and point to this download page.  Alternatively, you can download the files to a different machine and use FTP or SFTP to copy them over.
 +
# Download the following four files (source, source md5sum, data, data md5sum) into a directory and run the md5sum program to confirm you have an undamaged version of the distribution files.
 +
# Uncompress the distribution (tgz) files into data and source directory structures. The data files are nearly 3GB, but they are static and will not be modified and will not grow in size during use of the platform. The source directory is small, but this directory will increase as the platform is used, since the results produced by the platform will be stored here.
 +
# Configure your environment to add broadband platform directories into your python path and define other useful environment variables.
 +
# Build the executables by running the top level makefile.
 +
# Confirm the code is built correctly by running UnitTests.
 +
# Confirm the code runs correctly on your system by running AcceptanceTests.
 +
# Use the platform for research purposes.

Fig 1: Broadband Platform.

The SCEC Broadband Platform is a software system which generates 0-10 Hz seismograms for historical and scenario earthquakes in California.

Overview

The goal of the SCEC Broadband Simulation Platform is to generate broadband (0-10 Hz) ground motions for earthquakes using deterministic low-frequency and stochastic high-frequency simulations. The SCEC Broadband Platform is a collaborative software development project involving SCEC researchers, graduate students, and the SCEC/CME software development group. SCEC scientific groups have contributed modules to the Broadband Platform including rupture generation, low-frequency deterministic seismogram synthesis, high-frequency stochastic seismogram synthesis, and non-linear site effects. These complex scientific codes have been integrated into a system that supports easy on-demand computation of broadband seismograms. The SCEC Broadband Platform is designed to be used by both scientific and engineering researchers with some experience interpreting ground motion simulations.

Users may calculate broadband seismograms for both historical earthquakes (validation events including Northridge, Loma Prieta, and Landers) and user-defined earthquakes. The platform produces a variety of data products, including broadband seismograms, rupture visualizations, and goodness-of-fit plots. Users can install the platform on their own machine, verify that it is installed correctly, and run their own simulations on demand without requiring knowledge of any of the code involved. Users may run a validation event, supply their own simple source description, or provide a rupture description in SRF format. Users may specify their own list of stations or use a provided list. Currently the platform supports stations and events in Southern California, the Bay Area, and the Mojave. Users may select among various codebases for rupture generation, low-frequency synthesis, high-frequency synthesis, and incorporation of site effects, with the option of running a goodness-of-fit comparison against observed or simulated seismograms. These codes have been validated against recorded ground motions from real events.

The Broadband Platform was implemented using software development best practices, including version control, user documentation, acceptance tests, and formal releases, with the aim of ease of installation and use.

Current Release

The current official release of Broadband Platform is v11.2.3. This distribution was posted online on Wednesday, 09 May 2012. This is a "bug-fix" version of the platform that fixes a small number of bugs discovered in v11.2.2 since its release in October 2011. Details of the bugs fixes are provided in the release notes. No new features are introduced in this version of the platform. New Broadband platform users should work with this version of the software, and we recommend current Broadband platform users migrate to this new version whenever possible.

Dependencies

Broadband has the following dependencies:

A non-commercial copy of Intel c and FORTRAN compilers can be obtained by registering for a non-commercial account with Intel and downloading the compilers from the Intel website.

and the following optional dependencies for additional functionality:

  • GMT (for plotting)
  • Matlab with map toolbox (for certain platform modules)
  • PyGTK (for interactive plotting)

Downloads

To install and use the Broadband platform, you need both the source code and the data files. The broadband platform contains cumulative improvements to the geoscientific codes and software infrastructure. We recommend use of the most recent version of the broadband platform, unless you are trying to reproduce results generated with an earlier version of the platform.

Users that are upgrading from V11.2.0 to v11.2.3 should retrieve new versions of both the Broadband Platform data files and the Broadband Platform source code. Both were changed in this latest release.

There are detailed installation instructions in the Broadband User Guide Current.

The main steps involved in installing the platform as a local installation on Linux machine include:

  1. The software can be installed in an account on a Linux computer with at least 4GB of disk storage and C, Fortran, and Python software installed.
  2. From this Linux computer, start a web browser and point to this download page. Alternatively, you can download the files to a different machine and use FTP or SFTP to copy them over.
  3. Download the following four files (source, source md5sum, data, data md5sum) into a directory and run the md5sum program to confirm you have an undamaged version of the distribution files.
  4. Uncompress the distribution (tgz) files into data and source directory structures. The data files are nearly 3GB, but they are static and will not be modified and will not grow in size during use of the platform. The source directory is small, but this directory will increase as the platform is used, since the results produced by the platform will be stored here.
  5. Configure your environment to add broadband platform directories into your python path and define other useful environment variables.
  6. Build the executables by running the top level makefile.
  7. Confirm the code is built correctly by running UnitTests.
  8. Confirm the code runs correctly on your system by running AcceptanceTests.
  9. Use the platform for research purposes.

Broadband Platform v11.2.2, released in October 2011 is considered a 'bug-fix' release of Broadband Platform. Broadband Platform v11.2.2 contains the same functional capabilities as v11.2.1 with the following modifications.

  • Trac # 56 Convert BBP Matlab scripts to Python
  • Trac # 67 Rename the cleanup.py so that people do not run it accidentally
  • Trac # 68 Build Broadband with latest (2011) Intel and GNU compilers

11.2.1 - September 2011 - Bug-fix release List of Trac items fixed in this release:

  • Trac # 41 - Add License file (EULA) to Broadband distribution.
  • Trac # 42 - Add a file manifest to the distribution archives.
  • Trac # 46 - Remove Hardcoded Green_Bank.inf entries.
  • Trac # 47 - Syn1d Module fails with IO error due to missing file.
  • Trac # 54 - plot_SRF.csh fails with "Newline in variable name".
  • Trac # 61 - Provide an option to remove temporary folders at end of Broadband simulation run.
  • Trac # 62 - Add a warning and user prompt to comps/cleanup.py script.
  • Trac # 63 - Acceptance resume.txt should not be created in ref_data/accept_inputs.
  • Trac # 64 - Simulations with URS HF module fail with IOError and segmentation faults.
  • Trac # 65 - Add the XML file generated during a Broadband simulation to the output directory as metadata.
