QuakeSim Quarterly Update

QuakeSim Quarterly Update. Marlon Pierce, Geoffrey Fox. Fault DB Query Bugs Fixed. Fault DB correctly queried to get Faults with one segment (ie segment name is null). Same fault + segment from different references. GeoFEST, Disloc, and Simplex portlets all updated.

  1. QuakeSim Quarterly Update Marlon Pierce, Geoffrey Fox

  2. Fault DB Query Bugs Fixed • Fault DB correctly queried to get • Faults with one segment (ie segment name is null). • Same fault + segment from different references. • GeoFEST, Disloc, and Simplex portlets all updated. • Accompanied by some code reorganization that I needed to do anyway. • But note this is still using an older version of the DB (?). • And of course we want to push a lot of this into the DB web service.

  3. Daily and RealTime RDAHMM • Miscellaneous bug fixes to DailyRDAHMM • This should be ready for users • Need to discuss. • Movie generation service for DailyRDAHMM is in development. • Realtime RDAHMM being updated • Previous version was just running RDAHMM on 10 minutes of data with no training. Just to show it could be done. • Now using trained rdahmm workers. • Using 2 days worth of data for training. • Data collected and analyzed in 30 minute segments. • This is proof of concept for the infrastructure. • Need to know the real workflow: how long to train, how often to update, etc. • Training is computationally demanding, so frequent updates to the training sets will require more computing. • We can solve this with the TG using services that already exists (variants of the GeoFEST service). • May also need some filtering (ST_filter) of raw results.

  4. GeoFEST Related Stuff • Serial GeoFEST and mesh generator are still Grid enabled. • Parallel GeoFEST services and portlet will need some modifications, as the input file format has been extended. • New version of the code is available (?) • Running parallel GeoFEST as a service. • We have the BLAHP PBS plugin for Condor-G installed and are testing it on local PBS systems. • Will allow the existing GeoFEST service to work without Globus, since BLAHP talks directly to PBS. • I have an account at Ames and an RSA card. • Need some advice on how the service will fit into Ames’s security model. • We also played with running parallel GeoFEST on a “cloud” system of virtual machines. • Worked but performance was weird. • GeoFEST is probably not a good candidate for a virtual appliance, but other codes (RDAHMM, Disloc, Simplex, …) are.

  5. Disloc and Simplex • These had updated user interfaces from the last Quarterly meeting that still need to be reviewed. • Disloc: allows you to do the “scatter point” as well as the rectangular grid version. • Simplex: Can import GPS velocities from the Scripps GRWS.

  6. Some Next Steps • [Assumes nothing went horribly wrong in the previous slides] • GeoFEST services on Columbia, Cosmos • What is happening to Cosmos? • I’d still like to get parallel GeoFEST on some TeraGrid machines • Complete realtime rdahmm in some meaningful fashion. • Make a plan for Daily RDAHMM usage. • Move portal off gf7. • Too old and slow. • IU has web server hosting now thanks to OpenVZ. • Virtual California?
