ThIS on the Grid

Overview

User forum presentation on THIS: put the link here

Phone meeting of 19.03.2008

First phase

Plan

  • we assume that all input files are distributed on the Grid before the simulation starts (using JJS or whatever)
  • the stop criterion for the simulation is the total number of events performed on all worker nodes
  • the execution logic on the worker node - the goal is to reduce the number of output files produced:
    • download input files
    • loop while master asks for more events to be simulated
      • do the simulation of a bunch of events
      • suspend the application so that the next time the simulation is done the output files are updated
    • close output files and upload them to a SE
  • we use Ganga to submit worker agents and we use DIANE 2 to control the simulation

Actions

  • THIS: please upload the current simulation script run on the worker node
  • THIS: please upload the example of the simulation script with suspend functionality
  • CERN: prepare the first version of the application plugin to be used with DIANE 2.0
  • CERN: send instructions how to try it out in THIS environment
  • ALL: try it out and fix until it work wink

THIS Computing Environment

  • no shared file system between local user PC and the UI
  • are there open ports for incoming connections on the UI? to be checked

Next phases

  • probabilistic stop criterion for the simulation -- to be checked if large output files are needed to be transfered back to the master... ???
  • ...
