Abstract: A system processes streaming data and includes at least one processor. The system may write streaming data received from a data source as messages in queues at a queuing cluster. The queuing cluster includes a coordinator node to direct the messages to non-coordinator nodes of the queuing cluster. The system may retrieve the data from the queues based on subscription of topics and store the retrieved data in a consumable repository.

Abstract: It is detected that an error has occurred on an FPGA while the FPGA is operating in a first mode, wherein the error is not correctable by the FPGA itself. The FPGA is configurable to operate in the first mode in which a set of processing steps is to be performed by a first set of logic cells within the FPGA, or in a second mode in which at least a portion of the set of processing steps is to be performed outside the FPGA enabled by a second set of logic cells within the FPGA. An error location associated with the error is identified. In the event that the error location is deemed to have occurred in a critical subset of the first set of logic cells: the FPGA is switched to operate in the second mode; at least one of the first set of logic cells is reconfigured; and upon successful reconfiguration, the FPGA is switched to operate in the first mode.

Abstract: A computer-implemented method for shipping I/O operations to prevent replication failure may include 1) attempting to perform an I/O operation in a system configured to replicate data from a data cluster to another data cluster, 2) detecting a failure in at least part of the attempt to perform the I/O operation that threatens to fail the system's replication of data from the data cluster to the other data cluster, and, in response to detecting the failure, 3) shipping the I/O operation from a node originally responsible for servicing the I/O operation to another node to complete the I/O operation without failing the system's replication of data from the data cluster to the other data cluster. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A node includes: an arithmetic processing device; and a first memory, wherein the arithmetic processing device includes: a processor core; a storing circuit to store a first failure node list in which first information indicating that a failure has occurred or second information indicating that no failure has occurred is set for each of nodes; a request issuing circuit to issue a first request to a second memory provided at a first node among the nodes; a setting circuit to set the first information for the first node in the first failure node list when the first request has timed out; and an issuance inhibition circuit to inhibit, based on a second request to the second memory from the processor core, the second request from being issued by the request issuing circuit when the first information is set for the first node in the first failure node list.

Abstract: Method and apparatus for switching between a first server and a second server, each located within a virtual private cloud and the first server being located within a first zone and the second server being located within a second zone that is physically separate from the first zone. The method and apparatus further configured to determine that the first server has experienced a failure to send or receive data. The method and apparatus further configured to enable a second port on the second server. The method and apparatus further configured to create a new route table at the second server and flush the previous route table. The method and apparatus further configured to transmit, via the second port, a request to a virtual private cloud controller to update an elastic internet protocol address with the second port information and receive data from the virtual private cloud controller.

Abstract: Provided are a computer program product, system, and method for generating a health condition message on a health condition detected at a first server to send to a host system accessing the first server. A determination is made of a health condition with respect to access to a first storage. A determination is made of an estimated Input/Output (I/O) delay to access the first storage resulting from the determined health condition. A health condition message is generated indicating the estimated I/O delay. The health condition message is transmitted to the host system, wherein the host system uses the estimated I/O delay to determine whether to perform a swap operation to redirect host I/O requests to data from the first server to a second server.

Abstract: An immediate failover from a primary order book to a secondary order book is provided. The primary order book represents a current state of one or more orders according to a first node computing entity and the secondary order book represents a current state of all orders according to a second node computing entity. An input stream of order information is processed by the first node computing entity to generate (a) a primary order book and (b) an output stream of order information. A secondary stream of order information is provided to a second node computing entity. The second stream of order information is processed to generate a secondary order book. In the event of the first node computing entity experiencing a fault, the secondary order book can take over as the primary order book immediately and without any signification processing delays.
