Currently, AOTExecutor only supports heterogeneous execution by leveraging tir.call_extern via BYOC. In order to properly model a heterogeneous environment (in particular, to model multiple disjoint memories and leverage #8404), AOTExecutor needs to formally support invoking the Device API. It's currently not possible to do this from TIR via the AOT run-function.

  • Open a discuss forum post to debate how to properly model this in TIR, considering VirtualDevice
  • Write up a formal RFC
  • (yet TBD)
