Code review comment for lp://staging/~liuyq0307/lava-lab/keep-one-fastmodel-per-node

So, previous to this change we had:

fastmodels01
  rtsm_foundation-armv8_01
  rtsm_ve-a15x1-a7x1_01
  rtsm_ve-a15x4-a7x4_01
  rtsm_ve-a15x4-a7x4_02
  rtsm_ve-armv8_03
  rtsm_ve-armv8_04
fastmodels02
  rtsm_ve-armv8_01
  rtsm_ve-armv8_02
fastmodels03
  rtsm_foundation-armv8_02
  rtsm_ve-armv8_05

And after this change we would have:

fastmodels01
  rtsm_foundation-armv8_01
  rtsm_ve-a15x1-a7x1_01
  rtsm_ve-a15x4-a7x4_01
  rtsm_ve-a15x4-a7x4_02
  rtsm_ve-armv8_01

fastmodels02
  rtsm_ve-armv8_02

fastmodels03
  rtsm_foundation-armv8_02
  rtsm_ve-armv8_03

So in fact, your change does not remove multiple fast models except on one server, fastmodels02.

Perhaps the solution is to have a new device type, rtsm_ve-armv8-single which is guaranteed to run on a single node, and only provide one of those.

My main issue here is that if we have to have a server per fast model instance, then to support the current load and spread, and future new fast model types, I need 10 servers, at $2000 each, one per fast model instance. That seems rather excessive.

You will need to get authorisation from Mark Orvek for that sort of spend.
