Description

  • Currently sitewide on/off choice, can't choose per-workflow
  • Have to duplicate instance types in the config (obnoxious) (see #18596)
  • Records the wrong price (uses price from instance type config not actual information from the cloud)
  • Scheduling choices are too narrow, should be able to request different node types when the node you want isn't available
    • Could we query spot prices on the fly to make scheduling decisions
    • Try bigger instance types but only bid the spot price for the smallest node type
    • Should eventually escalate to an on-demand instance if spot instance isn't available
  • User should be able to communicate cost tolerance
  • Want to try other availability zones, but requires feature of Keepstore running on compute nodes (#16516)
  • Need better way to handle spot instance shutdown
    • Maybe just always retry on a regular cost node
  • Consider shutting down spot instances after a job because there is a timer?
    • Need to research this more
  • Can the VM be frozen / restored?
