Minutes from 2 February 2010

2010/02/02 CSEP Meeting

Attendees: Max W., Danijel S., John Y., Masha L.

  1. csep-op:
    1. From 2010/01/26 metting: Performance issue due to new NFS server:
      • John wants to try separating testing regions to different disks
        1. Masha said it's OK since all testing regions are independent from each other
    2. USC Matlab license R2009b got picked up by nightly processing on csep-op (since 2010/01/26)
      • Danijel suggested not to reprocess test dates when older R2007a is restored on the server
      • Nightly builds show problem only with STEP forecast
    3. New forecasts by Alvaro Gonzalez (introduced in CSEP V10.1.0) were generated since 02/01/2010 for Global and Western Pacific testing regions:
      • Alvaro is happy
    4. V10.1.0 is running on csep-op as of 2009/01/08:
  2. From 2010/01/26 meeting: Jeremy had a discussion with Peter Shebalin:
    • Should run alarm-based evaluation tests for EAST (alarm-based) model against EEPAS and PPE David Rhoades models (rate-based)
      • Masha responded that EAST model has a single magnitude bin vs. rate-based models having multiple magnitude bins
      • Jeremy said that alarm-based tests won't work then
      • Jeremy will get back to Masha regarding alarm-based tests for alarm-based model vs. rate-based model
  3. From 2009/12/15 meeting: Phil suggested to use iRODS as data management for CSEP:
    • John will look into it some time early January
    • John suggested to use VirtualMachine to distribute CSEP software
      1. Will need to have different images for different testing centers due to the installed forecasts models
  4. Software development:
    1. John installed USC provided Matlab licence 2009b on csep-cert:
      • To avoid failures when network goes down and Matlab license server goes down
      • STEP acceptance test is failing (forecast cells are shifted)
      • Masha contacted Matt who suggested to abandon Matlab version of STEP and install Java version of the model
        1. Java version might be ready by March, 2010
        2. Danijel suggested to withdraw Matlab STEP from testing from existing forecasts groups
        3. Will introduce new forecast group which will include Java STEP
    2. Group discussed priorities for known tasks:
      • Web service
      • Get rid of Matlab within testing center:
        1. Use QuakePy to prepare catalogs
        2. Use original Fortran code for declustering
    3. Trac tickets:
    4. High resolution Global testing region:
      1. Danijel reported that forecast template and format are being defined
      2. Yan sent out an announcement about "FULL EARTH HIGH-RESOLUTION (0.1x0.1 degree) EARTHQUAKE FORECASTS"
        • Using PDE catalog
        • Will integrate within CSEP when testing region is established
  5. From 2009/12/08 meeting: CSEP policies
    1. Should discuss if SCEC Testing Center results should be open to the public
      • Danijel will get back to the group
    2. Danijel will work on more content for the main CSEP web pages
  6. From 2009/10/06 meeting: Fabian presented slides for new implementation of CSEP results web viewer
    • Proposed to use Django based on Model-View-Controller paradigm
    • Split results viewer into:
      • web service for CSEP data products (maps, XML results datasets)
        • Use Database to store CSEP results by Dispatcher
          • John pointed out that it might be redundant to split already available XML results for injection to the database, then reconstruct XML from the database
          • John pointed out that would need to inject already existing data into the database
          • Masha is worried about making it error-prone due to the reprocessing
          • Very minimal work on operational CSEP software if only need to change to publish XML results vs. SVG plots
          • Fabian could work on implementation
          • Danijel suggested to create tests summaries by Dispatcher
            1. Masha suggested to implement visualization of the summary on web server site by CSEP Toolkit modules
      • interactive web application to present data products
        • Danijel asked about authentication for Japanese viewer
          • John suggested to use Apache's one
      • Danijel asked if it shold be integrated into Drupal?
        • John suggested to try a simple example to see if it works
      • James asked why not to use Plone
        • John said that we used to use Plone, but migrated away from it, but may be should investigate more
      • John asked how to discover what is available:
        1. Danijel suggested to use URL queries to discover
        2. Masha suggested that Dispatcher could update already existing configuration files for forecasts groups with current forecasts filenames and publish it as well
        3. John suggested to use allmodels.xml that current web viewer has
  7. From 2010/01/12 meeting: John and Masha discussed necessary changes to support web application to view CSEP results:
    • CSEP will publish already existing configuration file for each forecast group to the web server
    • Web service will use file system discover method to identify:
      1. avalable testing regions
      2. available forecasts groups within each testing region
    • Configuration file for each forecast group should include:
      1. Base name of currently tested forecast file
      2. Flag if forecast start date is part of the forecast filename
    • John asked if CSEP Dispatchers should publish any XML format files to the web server at all:
      1. May run into problem of displaying results for not finished evaluation tests
        • May introduce a "lock" to indicate if evaluation is in progress
      2. Makes sense not to duplicate results - especially the ones that nobody is going to look at
  8. Hardware:
    1. csep-cert
      • CSEPWebTest.py is not part of nightly build - some issues connecting to the web server
        1. John is looking at the problem
