Abstract: Access control is provided for peer-to-peer communication between a source peripheral device and a destination peripheral device without going through a host device. The access control mechanism can allow or block a request for a transaction to go out via a port of the source peripheral device to the destination peripheral device by comparing an attribute associated with the transaction with a filter attribute stored in memory. Embodiments of the disclosed technologies can allow programming of different filter attributes for different tenants in a multi-tenant environment.

The campaign server GUI enables the user to construct the campaign content and to launch the campaign towards members of the dynamically updated target segment. The campaign server further operates to collect and present campaign results to the user.

The backup manager identifies an end of a backup generation session for a virtual machine of the virtual machines and, in response to identifying the end of the backup generation session, identifies a continuity chain implicated by the backup generation session using the backup policies; performs a membership analysis of the identified continuity chain to identify a continuity state of the continuity chain; makes a first determination that the identified continuity chain is broken based on the identified continuity state; and, in response to the first determination, remediates the continuity chain.

Abstract: A multi-tenant environment is described with a configurable hardware logic platform (e.g., a Field Programmable Gate Array (FPGA)) positioned on a host server computer. The configurable hardware logic platform can be programmed with a host logic wrapper portion, which is controlled by a service provider, and a customer portion, which is programmed with logic provided by a tenant of the service provider. While the host logic wrapper portion is reprogrammed, protections are put in place to prevent a virtual machine or the customer logic from violating security built within the host logic wrapper portion. Such protections can be suspending communications between the virtual machine and the customer logic until the host logic wrapper is reprogrammed.

Abstract: Reference data is one type of data that the video accelerator may frequently be read from external memory. In various examples, the video accelerator can adaptively select inter-prediction modes based on the bandwidth to external memory that is available at any point in time. The video accelerator can determine the amount of bandwidth that is available, and when the bandwidth is insufficient for obtaining reference data for all possible inter-prediction modes, the video accelerator can use the encoding parameters of a neighboring block to select an inter-prediction mode to use. The video accelerator can then obtain a reference window for the selected inter-prediction mode, and perform prediction using the inter-prediction mode and the reference window.

Abstract: Methods and apparatus are disclosed for securely erasing partitions of reconfigurable logic devices such as FPGAs in a multi-tenant server environment. In one example, a method of securely erasing an FPGA includes identifying one partition of previously-programmed resources in the FPGA, erasing the identified partition by storing new values in memory or storage elements of the identified partition, and storing new values in memory or storage elements of additional external resources electrically connected to the integrated circuit and associated with the identified partition. Thus, other partitions and subsequent users of the identified partition are prevented from accessing the securely erased data. A configuration circuit, accessible by a host computer via DMA, can be programmed into the FPGA reconfigurable logic for performing the disclosed erasing operations.
