CS-SWIM Meeting Planning 6 March 2007

Short term pre-PSACI Users/advisory panel identified, invited (CS victims needed; Al Sussman, Andrew Seigel) Schedule for PS branch.  Request for capabilities, by 18 March  Branch 25 March or later  Need to have unbroken codes/executables for PSACI runs  Longer term schedule of PS upgrades (and concommittent requests for changes)

Short term pre-PSACI Primary science-driven sims needed  ITER start-up (run on PPPL mhd)  Porcelli test: Linear MHD (run on PPPL mhd)  Rate of tail formation on CMOD (requires Jaguar) At least first two require EPA component, need to get this working with current driver/fmwk  Propogation of time-step backtracking not essential (but we still must allow for it in fmwk and driver)

Short term pre-PSACI Have portal that  Provides active monitoring of job events  Monitoring via ElViz of desired physics thingies  Allows access to data management system for users to filter (via easily generated provenance data) among files generated during a SWIM run Job launch on PPPL systems from portal  Longer term to address others, esp Jaguar

Short term pre-PSACI Getting SWIM framework, driver, and configuration system documented, design explained Need schedule for when runs must be completed for analysis, and who does the runs (DB will propose this schedule)

Mid Term: between PSACI's Need capability for signaling between components (including driver component).  Need use scenarios delineated! Will only need (in fast MHD) to signal from a component when it completes, or from a component in mid- execution? Will a component need to signal in mid-execution for a service that it needs before it can continue? Can use (untested) exception model from CCA for this

Mid Term: between PSACI's Refine data management system  Get what data files, what data objects are of interest For monitoring For ease of extraction later More generally, use cases for portal and use of data by physicists here  Identification of most useful metadata (in end user terms, what kind of questions do you want to ask to locate data from SWIM runs?) Don: find the sim I did for a similar case, find the experimental data used with/for it.

Mid Term: between PSACI's Science runs needed for PSACI 2008  Timelines like for this year's to get geared up earlier  Need to fulfill promise to effectively use the Leadership Class Facility Address job launch from portal to LCF systems  Is this useful, or stick with having LCF runs done separately (but sending data/monitoring to portal) Issues of LCF systems; check particularly the PS being built since it is central.

Mid Term: between PSACI's Regression tests for components  Identification of a few test cases that can be used by CS people. Need not be complete coverage. Performance testing of components (including driver component) Build and configure system  Currently a top-level make system set up by Wael Review is about 1.x years from now. Need to also determine goals for it. Depends on cycle, but may need to detail goals earlier for it.
