Abstract: Technologies are provided for dynamically changing a size of a cache region of a storage device. A storage device controller writes data to the cache region of the storage device using a particular storage format. The storage device controller then migrates the cached data to a storage region of the device, where the data is written using a different storage format. A dynamic cache manager monitors input and output activity for the storage device and dynamically adjusts a size of the cache region to adapt to changes in the input and/or output activity. The dynamic cache manager can also adjust a size of the storage region. The storage device controller can automatically detect that the storage device has dynamic cache support and configure the storage device by creating the cache region and the storage region on the device.

Abstract: A method for in-band de-duplication, the method may include receiving by a hardware accelerator, a received packet of a first sequence of packets that conveys a first data chunk; applying a data chunk hash calculation process on the received packet while taking into account a hash calculation result obtained when applying the data chunk hash calculation process on a last packet of the first sequence that preceded the received packet; wherein the calculating of the first data chunk hash value is initiated before a completion of a reception of the entire first data chunk by the hardware accelerator.

Abstract: Methods, systems, and computer-readable media for virtualizing graphics processing in a provider network are disclosed. A virtual compute instance is provisioned from a provider network. The provider network comprises a plurality of computing devices configured to implement a plurality of virtual compute instances with multi-tenancy. A virtual GPU is attached to the virtual compute instance. The virtual GPU is implemented using a physical GPU, and the physical GPU is accessible to the virtual compute instance over a network. An application is executed using the virtual GPU on the virtual compute instance. Executing the application generates virtual GPU output that is provided to a client device.

Abstract: A resource manager of a virtualized computing service indicates to a client that FPGA-enabled compute instances are supported at the service. From a set of virtualization hosts of the service, a particular host from which an FPGA is accessible is selected for the client based on an indication of computation objectives of the client. Configuration operations are performed to prepare the host for the application, and an FPGA-enabled compute instance is launched at the host for the client.

Abstract: A resource request is received by a network device from a virtual machine running on a host. The resource request includes a requested resource size. The network device allocates resources of the network device in response to the resource request. A resource response is sent by the network device to the virtual machine that generated the resource request. The resource response includes a location of the allocated resource.

Abstract: Provided are systems and methods for connection establishment over a network that does not require a user application to establish an explicit connection with a target application. In some implementations, provided is an apparatus configured to communicate with a network and a host device. The apparatus may receive a message and destination information associated with the message from the host device. The apparatus may further determine, using the destination information, a transport context from a plurality of transport contexts. The transport context may include a state of a connection with a destination on the network. The destination on the network may be associated with the destination information.

Abstract: The following description is directed to a logic repository service supporting adaptable host logic. In one example, a method of a logic repository service can include receiving a first request to generate configuration data for configurable hardware using a specification for application logic. The method can include selecting a particular host logic shell from a group of host logic shells. The particular host logic shell can be used to encapsulate the application logic when the configurable hardware is configured. Configuration data for the configurable hardware can be generated. The configuration data can include data for implementing the application logic and at least a portion of the particular host logic shell. The method can include receiving a second request to download the configuration data to a host server computer comprising the configurable hardware. The configuration data can be transmitted to the host server computer in response to the second request.

Abstract: A network device stores information associated with a packet in a queue. The network device sends an interrupt to a host to notify the host of completion of processing the packet. A Memory-Mapped Input/Output (MMIO) write transaction is received that includes a pointer update associated with the queue and an interrupt unmasking value. The pointer is updated and the interrupt is unmasked based on receiving the single MMIO write transaction.

Abstract: A computing system can include a server computer and a configurable hardware platform. The server computer can include instances or domains such as a management partition and a user partition. The management partition can be used to perform management services for the user partitions and the configurable hardware platform. The configurable hardware platform is coupled to the server computer, and can include a host logic and a configurable application logic. In an embodiment, the computing system is configured to provide the user partition with physical or virtual access to a first part of the configurable hardware platform through the host logic in the configurable hardware platform. The computing system is also configured to provide the user partition with virtual access to certain portions/resources associated with the configurable hardware platform.
