1. A system comprising:
a host platform including a processing device and virtual machine monitor (VMM), the host platform hosting one or more virtual machines (VMs);
a plurality of graphics processing apparatuses coupled to the host platform using a host fabric, the plurality of graphics processing apparatuses coupled together using a scale-up fabric;
a graphics processing apparatus from the plurality of graphics processing apparatuses comprising:
one or more graphics processing engines;
a memory;
a memory management unit (MMU) including a GPU second level page table and GPU dirty bit tracker;
a provisioning agent to:
receive a request from the VMM to provision a subcluster of graphics processing apparatuses, the subcluster including a plurality of graphics processing engines that comprise a first portion of graphics processing engines within the one or more graphics processing engines on the graphics processing apparatus and a second portion of graphics processing engines on a second graphics processing apparatus;
provision the scale-up fabric to route data within the subcluster of graphics processing apparatuses; and
provision a plurality of resources including the first portion of graphics processing engines on the graphics processing apparatus for the subcluster of graphics processing apparatuses based on the request from the VMM; and
a migration agent, the migration agent to:
responsive to a request to migrate GPU state from the subcluster of graphics processing apparatuses to a second subcluster of graphics processing apparatuses coupled to a second host platform,
identify a portion of the memory that was written to while another portion of memory was transferred to the second subcluster;
determine the portion of the memory is below a threshold; and
send a message to the VMM indicating the portion of the memory and further indicating that the subcluster is ready to be migrated.
