Machine / Job Features Task Force

MJF introduction

Machine/Job features are a means to provide information from a resource provider (batch system, IaaS) to the payload. This information can be static (eg. power of the machine, number of cores, local scratch space) or dynamic (eg. shutdown time of a VM). Use cases cover areas such as

  • Provide a shutdown time for a virtual machine
  • Provide number of cores available to a payload
  • Provide how much work can be executed within a remaining queue
  • Provide information on the disk space available for local usage by the job

Task force mandate

The mandate of this task force sets out these goals:

The context of this task force are WLCG resource providers in both batch and virtualized environments for compute intensive data processing activities and all LHC VOs interested in using the information provided.
