Abstract: The present disclosure relates to a system and a process for producing biofuel. The system comprises at least one feed tank; a low pressure pump; a high pressure pump; a first heat exchanger; a second heat exchanger; a reaction vessel; a precipitation vessel; a first pressure let-down station; a third heat exchanger; a second pressure let-down station; a gas-liquid separator; and a biofuel separator. The process comprises pressurizing and heating a feed, followed by reforming the pressurized and heated feed to obtain a slurry. The solids are separated from the slurry by precipitation to obtain a mixture comprising biofuel and the non-reformed feed. The mixture is then cooled and de-pressurized, followed by separation of gases and the non-reformed feed to obtain the biofuel. The system and process of the present disclosure can be used to produce biofuel from diverse, easily available and inexpensive starting material.

Abstract: One embodiment of the present invention provides a switch. The switch includes a management mechanism and a configuration mechanism. During operation, the management mechanism is configured to operate the switch in conjunction with the partner switch as a single logical switch. The configuration mechanism is configured to assign a virtual switch identifier to the logical switch.

Abstract: A network device monitors the traffic of individual flows through one of its ingress ports and, if the traffic volume exceeds a predetermined threshold, signals for a reduction in data traffic volume transmitted to that ingress port from one or more source devices. Example signals may include without limitation a unicast congestion message sent to the source of a flow, an Explicit Congestion Notification to one or more source devices, and the dropping of packets by the receiving device. In response to such signals, one or more of the source devices decrease the transmission rate of data traffic to the receiving device.

Abstract: A technique for interrupt moderation allows coalescing interrupts from a device into groups to be processed as a batch by a host processor. Receive and send completions may be processed differently. When the host is interrupted for receive completions, it may check for send completions, reducing the need for interrupts related to send completions. Timers and a counter allow coalescing interrupts into a single interrupt that can be used to signal the host to process multiple completions. The technique is suitable for both dedicated interrupt line and message-signaled interrupts.

Abstract: Computer-implemented systems, methods, and computer-readable media electronic for financial transfers include: receiving a request for a set of at least one Icheck tokens; generating the set of Icheck tokens, each Icheck token including a unique identifier, a set of payer data, and a set of signature data, wherein each Icheck token is configured to be transferable over plural media; transmitting the set of Icheck tokens to a payer device; receiving from a payee device an Icheck token from the set of Icheck tokens; authenticating the Icheck token by analyzing at least one of the unique identifier, the set of payer data, and the set of signature data; transmitting a non-payment notice if the authenticating step reveals the Icheck token is not authentic; and transmitting payment according to the set of signature data if the Icheck token is authentic.

Abstract: A quality of service (QoS) notification module can provide detection and notification of violation of allocated QoS to a transmission queue. The QoS notification module can be located on a network adapter and send notifications to a host computer coupled to the network adapter. QoS notifications can indicate that one or more host transmission queues are being underserved, i.e., the bandwidth guaranteed to the one or more host queues is not being met despite the queues not being empty. Notification module can send notification to the host by writing to a memory location or a notification register in the memory of the host. Alternatively, the notification module can send an interrupt to the host processor, the interrupt including QoS notification information. The notification module can also be located in a switch for generating notifications of QoS violations of bandwidth guarantees for transmission queues associated with transmission ports of the switch.

Abstract: A new transport protocol between the IP layer and the DDP layer for use with RDMA operations. The embodiments all operate on a CEE-compliant layer 2 Ethernet network to allow the new transport protocol to be simplified, providing higher performance and simpler implementation. The new protocol allows a CEE-compliant layer 2 Ethernet network to provide data networking using IP, storage using FCoE, and RDMA using IP and the new transport protocol, without suffering the previous performance penalties in any of these aspects.
