Systems, apparatuses, and methods for accelerating page migration using a two-level bloom filter are disclosed. In one embodiment, a system includes a GPU and a CPU and a multi-level memory hierarchy. When a memory request misses in a first memory, the GPU is configured to check a first level of a two-level bloom filter to determine if a page targeted by the memory request is located in a second memory. If the first level of the two-level bloom filter indicates that the page is not in the second memory, then the GPU generates a page fault and sends the memory request to a third memory. If the first level of the two-level bloom filter indicates that the page is in the second memory, then the GPU sends the memory request to the CPU.
