CAE Productivity Challenges are Growing

• CAE Workflow Bottlenecks
• I/O related to end-user collaboration-intensive
  tasks
• Long times in movement of model domain
  partitions to nodes
• Post-processing of large files owing to their
  network transfer
• Case and data management (movement) of CAE
  simulation results
• CAE Workload Bottlenecks
• I/O related to parallel cluster
  compute-intensive tasks
• Thru-put of mixed-disciplines competing for
  same I/O resource
• Transient CFD (LES, etc.) with increased
  data-save frequency
• Large-DOF CSM implicit with out-of-core I/O
  requirements
• MM-element CSM explicit with 1000s of
  data-saves
• Non-deterministic modeling automation and
  parameterization
• General application of multi-scale,
  multi-discipline, multi-physics
