Abstract: Systems and methods are provided for dynamic GPU-enabled VM provisioning across cloud service providers. An example method can include providing a VM pool that includes a GPU-optimized VM and a non-GPU-optimized VM operating in different clouds. A control plane can receive an indication that a user has submitted a machine-learning workload request, determine whether a GPU-optimized VM is available and instruct the non-GPU-optimized VM to send the workload to the GPU-optimized VM in a peer-to-peer manner. The GPU-optimized VM computes the workload and returns a result to the requesting VM.
