Abstract: Techniques for efficiently purging non-active blocks in an NVM region of an NVM device using pointer elimination are provided. In one set of embodiments, a host system can, for each level 1 (L1) page table entry of each snapshot of the NVM region, determine whether a data block of the NVM region that is pointed to by the L1 page table entry is a non-active block, and if the data block is a non-active block, remove a pointer to the data block in the L1 page table entry and reduce a reference count parameter associated with the data block by 1. If the reference count parameter has reached zero at this point, the host system purge the data block from the NVM device to the mass storage device.

The disclosure provides an approach for setting up the kernel and its working set on a compute accelerator, executing the workload, suspending the workload, and then resuming the workload at a later time, optionally on a different host computer.

Abstract: Some embodiments provide a method for managing multiple queues of a network interface card (NIC) of a host computer that executes a data compute node (DCN). The method defines first, second, and third subsets of the queues. The first subset of queues is associated with a first feature for processing data messages received by the NIC, the second subset of queues is associated with a second feature, and the third subset is associated with both features. The method receives a request from the DCN to process data messages addressed to the DCN using both the first and second features. The method configures the NIC to direct data messages received for the DCN to a queue that is selected from the third subset of queues.

Abstract: Techniques for emulating geometry shaders and stream output using compute shaders are provided. In one set of embodiments, a geometry shader/stream output (GS/SO) emulation module can receive a geometry shader defined by an application for execution via a geometry shader stage of a graphics processing unit (GPU) of a computer system, where the geometry shader comprises program code for processing an input primitive. The GS/SO emulation module can further convert the geometry shader into one or more compute shaders, where the one or more compute shaders incorporate the program code of the geometry shader. The GS/SO emulation module can then issue the one or more compute shaders to a graphics driver of the computer system for execution via a compute shader stage of the GPU.

Abstract: MAC addresses are flexibly and dynamically allocated across groups of devices that need MAC addresses. MAC address pools are defined for the groups by non-overlapping ranges of MAC addresses. The range of MAC addresses defined for any pool may be shrunk to support an expansion of the range of MAC addresses of another pool. The maximum number of universally-administered MAC addresses that can be defined for any MAC address pool is greater than 216, and the maximum number of locally-administered MAC addresses that can be defined for any MAC address pool is greater than 238.

An IP address cache can also be employed to speed a subsequent IP address assignment by the imaging service.

Abstract: Some embodiments establish for an entity a virtual network over several public clouds of several public cloud providers and/or in several regions. In some embodiments, the virtual network is an overlay network that spans across several public clouds to interconnect one or more private networks (e.g., networks within branches, divisions, departments of the entity or their associated datacenters), mobile users, and SaaS (Software as a Service) provider machines, and other web applications of the entity. The virtual network in some embodiments can be configured to optimize the routing of the entity's data messages to their destinations for best end-to-end performance, reliability and security, while trying to minimize the routing of this traffic through the Internet. Also, the virtual network in some embodiments can be configured to optimize the layer 4 processing of the data message flows passing through the network.

Abstract: A system and method for providing quality of service (QoS) for clients running on host computers to access a common resource uses a resource pool module and a local scheduler in at least one of the host computers. The resource pool module operates to compute an entitlement of each client for the common resource based on a current capacity for the common resource and demands of the clients for the common resource. In addition, the resource pool module operates to assign a portion of the computed current capacity for the common resource to a particular host computer using the computed entitlement of each client running on the particular host computer. The local scheduler operates to allocate the portion of the computed current capacity among the clients running on the particular host computer.
