    Abstract: Various embodiments are generally directed to virtualized systems. A first guest memory page may be identified based at least in part on a number of accesses to a page table entry for the first guest memory page in a page table by an application executing in a virtual machine (VM) on the processor, the first guest memory page corresponding to a first byte-addressable memory. The execution of the VM and the application on the processor may be paused. The first guest memory page may be migrated to a target memory page in a second byte-addressable memory, the target memory page comprising one of a target host memory page and a target guest memory page, the second byte-addressable memory having an access speed faster than an access speed of the first byte-addressable memory.

    Abstract: Techniques for scalable virtualization of an Input/Output (I/O) device are described. An electronic device composes a virtual device comprising one or more assignable interface (AI) instances of a plurality of AI instances of a hosting function exposed by the I/O device. The electronic device emulates device resources of the I/O device via the virtual device. The electronic device intercepts a request from the guest pertaining to the virtual device, and determines whether the request from the guest is a fast-path operation to be passed directly to one of the one or more AI instances of the I/O device or a slow-path operation that is to be at least partially serviced via software executed by the electronic device. For a slow-path operation, the electronic device services the request at least partially via the software executed by the electronic device.

    Abstract: Systems and methods for container access to graphics processing unit (GPU) resources are disclosed herein. In some embodiments, a computing system may include a physical GPU and kernel-mode driver circuitry, to communicatively couple with the physical GPU to create a plurality of emulated GPUs and a corresponding plurality of device nodes. Each device node may be associated with a single corresponding user-side container to enable communication between the user-side container and the corresponding emulated GPU. Other embodiments may be disclosed and/or claimed.

    Abstract: Embodiment of this disclosure provides a mechanism to extend a workload instruction to include both untranslated and translated address space identifiers (ASIDs). In one embodiment, a processing device comprising a translation manager is provided. The translation manager receives a workload instruction from a guest application. The workload instruction comprises an untranslated (ASID) and a workload for an input/output (I/O) device. The untranslated ASID is translated to a translated ASID. The translated ASID inserted into a payload of the workload instruction. Thereupon, the payload is provided to a work queue of the I/O device to execute the workload based in part on at least one of: the translated ASID or the untranslated ASID.
