Abstract
A mechanism is described for mitigating the effects of such a DoS attack by detecting a multiple TDR situation within a short duration, identifying the errant virtual machines, and suspending all rendering ability for that virtual machine or set of virtual machines. While the disclosed embodiments are described in the context of virtual machines, the principles may be extended to the general problem of DoS attacks due to TDRs and bugchecks on any physical machine that includes a GPU. For example, DoS attacks can be generated from web sites directly using GPU rendering.
