3rd AGORA Workshop in 2014

We are delighted to announce that the 3rd Workshop for the AGORA Project will be held 15-18 August 2014 at the University of California, Santa Cruz.  The workshop is sponsored by the University of California High-Performance AstroComputing Center (UC-HiPACC).  

- Looking for the workshop in 2012 or 2013?
- To learn about what was discussed during the 3rd Workshop, please go to this page in the Project Workspace!  

Venue and Travel

On Aug. 15 the Workshop will be in the Simularium, Rm 180 of the Engineering 2 (E2) Building in the northwest corner of UC Santa Cruz campus, on Science Hill (click here to see a map of the E2 Building).  This will be a joint session with the annual Santa Cruz Galaxy Workshop 2014.  On Aug. 16-17 the Workshop will move to Rm 102 of the Interdisciplinary Science Building (ISB; click here to see a map of the ISB).

    (2) For a detailed direction to the meeting venue and the parking nearby, please go to the "General Info" tab in the Santa Cruz Galaxy Workshop 2014 webpage.  You may find it useful to visit the link for visitors by the Department of Astronomy and Astrophysics at UC Santa Cruz.  If you opt to use local public transportation the Santa Cruz Metro schedule to and from the UC Santa Cruz campus might be helpful.  

    (3) No housing will be available on campus this summer.  We recommend that if you plan to attend the conference, you arrange for lodging early.  Although each hotels policies vary, ask if there is a special rate for UCSC.  You may find information about local lodging options in the "General Info" tab in the Santa Cruz Galaxy Workshop 2014 webpage.    


    (1) This year we intend to make the workshop exclusively focused on working sessions for Papers “2”, "3" and “4” to push these papers out by the end of this year (more information here about each Paper; membership required).  All the simulation talks will be on Friday (Aug. 15) during the joint session with the Santa Cruz Galaxy Workshop 2014.  But except an 1-hour collaboration-wide meeting, the entire Saturday and Sunday will be devoted to working sessions.  Remote participation will be arranged.

    (2) We may include working sessions for science-oriented working groups to coordinate imminent future hydrodynamic simulations.  Feel free to suggest any topic to the Steering Committee or the Project coordinator.

"To-do Items for Papers 3 and 4" 
by Oscar Agertz (slides)

● Discussion:
 - Ellipsoidal ICs: readability in all codes
 - Start DM-only Proof-of-Concept run at high resolution (~100 pc)
 - Refinement strategy
 - Data storage strategy
 - How to resolve timing discrepancy

 Participants and the link to the result of this session can be found here

● Discussion:
 - New Grackle API: if the wrapper is in place for most codes, perform a comparison using a one-zone cooling test. An example would be to plot temperature vs time for a single cell starting at n=0.1 cm-3 and T=106 K.
 - Disk initial conditions: compare isolated disk ICs (vrot, \Sigmagas, etc ).
 - Refinement strategy: for mass-based refinement in grid codes, what is the appropriate mass to refine on (MSPH kernel, Mgas particle?). Choices for gravitational softening vs smoothing kernel size in SPH?
 - Feedback: agree on a baseline implementation of feedback for the disk test
 - Other subgrid physics: e.g. SF law, SF density threshold, enrichment (Kim et al. 2014) and the use of a pressure floor.
 - Advanced/actual comparison: in either an isolated disk or a 1011 Msun cosmological halo. Agree on a suite of simulations for the isolated disk (e.g. cooling only, cooling+star formation, cooling+SF+feedback)

1-hour discussion for Working Group XIII - BH accretion & feedback
led by Alex Hobbs
in parallel with the two other sessions
● Discussion:
 - We will choose one accretion model for cosmological runs, implement it across all codes and run simulation.
 - We will decide upon the mode of feedback (thermal/kinetic).  We also need to ensure that the feedback implementation is consistent between SPH and AMR. 
 - We will also decide upon a merger strategy and a seeding strategy.  We may have to decide if we fix the BH to the center of the potential to prevent wandering.
