Abstract: A circuit system includes a first integrated circuit die having a first group of circuits configured to perform a first set of operations. The circuit system also includes a second integrated circuit die having a second group of circuits configured to start performing a second set of operations with a delay after the first group of circuits starts performing the first set of operations to reduce power supply voltage droop. The operations performed by the first and second groups of circuits can be interleaved with a fixed or a variable delay. Logic circuits can be partitioned into the first and the second groups of circuits based on predicted switching activity of the logic circuits. Decoupling capacitors in integrated circuit dies can be coupled together to reduce droop in a supply voltage during a high current event.

Abstract: Some embodiments of the invention provide a novel method for specifying firewall rules. In some embodiments, the method provides the ability to specify for a particular firewall rule, a set of network nodes (also called a set of enforcement points below) at which the particular firewall should be enforced. To provide this ability, the method of some embodiments adds an extra tuple (referred to below as the AppliedTo tuple) to a firewall rule. This added AppliedTo tuple lists the set of enforcement points at which the firewall rule has to be applied (i.e., enforced).

Abstract: Described herein are systems, methods, and software to manage the encapsulation of layer two communications across computing sites. In one example, a gateway at a first computing site may receive an encapsulated packet from a second gateway at a second computing site. After receiving the encapsulated packet, the gateway decapsulates the encapsulated packet and determines that the decapsulated packet satisfies MSS criteria. The gateway further, in response to determining that the decapsulated packet satisfies the MSS criteria, modifies an MSS option associated with the decapsulated packet to a maximum value and forwards the decapsulated packet to a destination virtual node in the first computing site.

Abstract: Some embodiments provide various methods for offloading operations in an O-RAN (Open Radio Access Network) onto control plane (CP) or edge applications that execute on host computers with hardware accelerators in software defined datacenters (SDDCs). At the CP or edge application operating on a machine executing on a host computer with a hardware accelerator, the method of some embodiments receives data, from an O-RAN E2 unit, to perform an operation. The method uses a driver of the machine to communicate directly with the hardware accelerator to direct the hardware accelerator to perform a set of computations associated with the operation. This driver allows the communication with the hardware accelerator to bypass an intervening set of drivers executing on the host computer between the machine's driver and the hardware accelerator. Through this driver, the application in some embodiments receives the computation results, which it then provides to one or more O-RAN components (e.g.
