  • Patent number: 12316773
    Abstract: A method for managing message delivery in a computing infrastructure. For each message to be delivered, the message is sent simultaneously by a transmitting component, to each server of a plurality of receiving servers. For each server that received the sent message, the server computes a signature specific to the message received, which is identical for each server, and the server sends the computed signature to a synchronization component. The sent signature is received by the synchronization component. If a first condition according to which the received signature is not stored in a signature database is met, the received signature is stored in the signature database and an instruction is sent to store or transmit the received message to the server by the synchronization component. Otherwise, the synchronization component sends an instruction to the server to delete the received message and the computed signature.

    Abstract: A method for optimizing energy consumption of a computing infrastructure comprising a plurality of compute nodes, each associated with a plurality of jobs. The method includes receiving an energy consumption reduction request comprising an energy consumption reduction objective; determining a set of jobs to be suspended; and sending, to a runtime environment of each compute node associated with a job comprised in the determined set of jobs, a suspension request comprising said job. Upon receiving the suspension request, the method includes suspending the job comprised in the received suspension request, the suspension being carried out via a set of non-native instructions implemented in the runtime environment of each compute node; and active waiting by the suspended job for a suspension stop message comprising said suspended job, the active waiting being carried out via a set of non-native instructions implemented in the runtime environment of each compute node.

In one example, the method includes optimizing a circuit quantum electrodynamics (cQED) system to render a f0g1 reset unconditional by: minimizing an amplitude of a dispersive shift between the secondary quantum subsystem and the transmon qubit; and minimizing a reset duration. Additional steps include performing a f0g1 reset, wherein the f0g1 reset may be done simultaneously or sequentially.

  • Patent number: 11748524
    Abstract: An obfuscation circuit relies on a tamper-resistant nonvolatile memory which encodes a trusted Boolean function. The Boolean function is used to enable several operations relating to circuit obfuscation, including obfuscation of logic circuitry, obfuscation of operand data, and release of IP blocks. The tamper-resistant nonvolatile memory is part of a trusted integrated circuit structure, i.e., one fabricated by a trusted foundry, separate from another integrated circuit structure which contains the various operational logic circuits of the design and is fabricated by an untrusted foundry. The Boolean function is encoded based on a look-up table implemented as a cascaded multiplexer circuit. Multiple obfuscation functions can be so encoded. The obfuscation functions may be reprogrammed using a protocol that relies on symmetric keys, one of which is stored in the tamper-resistant nonvolatile memory.
