Abstract: In a first embodiment of the present invention, a method for generating a random number for an instance of a hardware description language definition is provided, the method comprising: generating a unique signature for the instance; applying a message digest generation process on the unique signature to arrive at a message digest having a fixed length; and applying a random number generation process on the message digest.

Abstract: A PCIe switch implements a logical device for use by connected host systems. The logical device is created by logical device enabling software running on a host management system. The logical device is able to consolidate one or more physical devices or may be entirely software-based. Commands from the connected host are processed in the command and response queues in the host and are also reflected in shadow queues stored in the management system. A DMA engine associated with the connected host is set up to automatically trigger on queues in the connected (local) host. Commands are sent to the physical devices to complete the work and a completion signal is sent to the management software and a response to the work is sent directly to the connected host, which is not aware that the logical device is non-existent and is implemented by software in the management system.
