Various embodiments are provided for providing byte granularity accessibility of memory in a unified memory-storage hierarchy in a computing system by a processor. A location of one or more secondary memory medium pages in a secondary memory medium may be mapped into an address space of a primary memory medium to extend a memory-storage hierarchy of the secondary memory medium. The one or more secondary memory medium pages may be promoted from the secondary memory medium to the primary memory medium. The primary memory medium functions as a cache to provide byte level accessibility to the one or more primary memory medium pages. A memory request for the secondary memory medium page may be redirected using a promotion look-aside buffer ('PLB') in a host bridge associated with the primary memory medium and the secondary memory medium.

Embodiments for providing direct access to non-volatile memory by a processor. One or more accelerators may be provided, via an application programming interface ('API'), direct access to non-volatile storage independent of a host central processing unit ('CPU') on a control path or data path to perform a read operation and write operation of data.

Providing direct data access between accelerators and storage in a computing environment, wherein the direct data access is independent of host CPU and the host CPU transfers object map identifying object of the data

Embodiments for crash recoverability for graphics processing units (GPUs) by a processor. GPU application data and kernel execution state of one or more GPUs may be checkpointed. The checkpointed GPU application data and the kernel execution state may be recovered. The checkpointed GPU application data and the kernel execution state may be persisted on non-volatile memory.
