Abstract: A hard input low density parity check decoder is provided that shares logic between a bit-flipping decoder and a syndrome calculator. The hard-decision decoder decodes one or more error-correcting (EC) codewords and comprises a bit-flipping decoder that flips one or more bit nodes connected to one or more unsatisfied parity checks; and a syndrome calculator that performs a parity check to determine whether the bit-flipping decoder has converged on a valid codeword, wherein the bit-flipping decoder and the syndrome calculator share one or more logic elements. The decoder optionally includes means for updating a parity check equation of each flipped bit. Error-correcting (EC) codewords are decoded by flipping one or more bit nodes connected to one or more unsatisfied parity checks; and updating one or more parity check equations associated with the one or more bit nodes each time the one or more bit nodes are flipped. The parity check equations are updated whenever a bit is updated.

Abstract: A novel RDMA connection failover technique that minimizes disruption to upper subsystem modules (executed on a computer node), which create requests for data transfer. A new failover virtual layer performs failover of an RDMA connection in error so that the upper subsystem that created a request does not have knowledge of an error (which is recoverable in software and hardware), or of a failure on the RDMA connection due to the error. Since the upper subsystem does not have knowledge of a failure on the RDMA connection or of a performed failover of the RDMA connection, the upper subsystem continues providing requests to the failover virtual layer without interruption, thereby minimizing downtime of the data transfer activity.

Abstract: A method and apparatus for providing redundancy in an Automatic Teller Machine (ATM) is provided. Application software may be run on top of a virtual environment such as a virtual machine and/or a virtual disk environment. Should a software component fail, the virtual environment will “crash” but the ATM hardware and operating system will remain intact. If the software is fatally flawed—e.g., due to a faulty “upgrade” the older version may be “rolled back” from a previously stored virtual environment.

Abstract: An approach is provided for migrating a live instance of a virtual machine from a source computer system to a target computer system. The approach operates by creating a consistent snap shot image of an operating system environment that is running the live instance of the virtual machine on the source computer system. A test virtual machine container is created based on an actual virtual machine container that corresponds to the live instance of the virtual machine. Based on the snap shot image of the operating system environment, a test virtual machine is created in the test virtual machine container. The generated test virtual machine is tested with a migration of the live instance of the virtual machine being performed in response to a successful test of the test virtual machine. The migration is aborted in response to an unsuccessful test of the test virtual machine.
