GIMI Init Script in Exper Mgmt Envir (EME)

1) Goals

The GIMI init script in EME aims to interactively initialize the experiment environment for each user-running experiment.

2) Tasks for Init Script

• Get experiment name from user, and derive experiment-id
• Retrieve project_id from omni or CH
• Get list of slice_ids from omni or CH, select slice_id for this experiment
• Get sliver_manifests_rspecs from AMs
• Parse sliver_manifest_rspec to get slice_node_names (fully qualified)
• Select default GIMI Portal, or override
• Setup GSAS (iRODS) structure
  • derive defaults for user_irods_home_directory and
  • target(exper)-directory, or override
  • derive and load proj_exper_step_descriptors
  • load template OMF scripts
  • get user_irods_target(exper)_iticket, assigned to selcted GIMI Portal agent
• Push sliver_manifest_rspecs and exp_descriptors to iRODS
• Holding user_credentials, config GIMI Portal exper info:
  • user_identity
  • experiment_id,
  • project_id, and slice_id
  • slice_node_names
  • sliver_manifest_rspecs
  • user_irods_home_directory
  • user_irods_target(exper)_directory
  • user_irods_target(exper)_iticket
