WLCG Accounting Task Force


The WLCG Accounting Task Force is set up following the outcome of the WLCG Accounting Review at the (pre-)GDB in April 2016.

The highest priority task for the Task Force is to address current issues with CPU/Wall clock accounting. Storage Space accounting should be also addressed in particular of what concerns understanding of the requirements of the experiments and sites, however with lower priority.


CPU/Wall clock accounting

  • to agree with all stakeholders on the content of the accounting portal and accounting reports (metrics, units, aggregation in terms of time and set of attributes like site, VO, country, etc…);
  • coordinate with APEL and accounting portal development team and follow up on the progress
  • validate the new version of the portal, ideally a dedicated customized UI for WLCG, and make sure that the requirements of the stakeholders are addressed
  • validate accounting data, ensure that it is correct in the APEL repository and manual fixes could be avoided
  • follow up of on whether/ how we enable injection of the opportunistic resources to APEL and accounting portal
  • coordinate with sites which provide their resources through cloud interfaces making sure that their resources are properly published in APEL. Debug corner cases when they are not properly published

Storage space accounting

  • agree with the experiments and sites on the functionality which is required for the WLCG storage space accounting system considering the use case of the high level overview of the total and available space
