  • Patent number: 11989078
    Abstract: A vehicle control device and a method thereof are provided. A master processor and a slave processor simultaneously receive, monitor or process signals of a vehicle, a power management module monitors the master processor via a first watchdog signal, and the master processor monitors the slave processor via a second watchdog signal. When the power management module sends the first watchdog signal to the master processor and no response message is received, the power management module sends a first reset signal to reset the master processor, and when the master processor sends the second watchdog signal to the slave processor and no response message is received, the master processor sends a second reset signal to reset the slave processor. When the master processor and the slave processor are abnormal, a forced wake-up module outputs a high level signal to forcibly wake up the master processor and the slave processor.

  • Publication number: 20130275801
    Abstract: A computer program product for performing error recovery is configured to perform a method that includes creating, by a processor, a recovery checkpoint. The processor is dynamically switched into a non-recoverable processing mode of operation based on creating the software recovery checkpoint. The non-recoverable processing mode of operation is a mode in which a subset of hardware error recovery resources are powered-down or re-purposed for instruction processing. It is determined, during the non-recoverable processing mode of operation, that a new software recovery checkpoint is required. Based on the determining that a new software recovery checkpoint is required, the processor is dynamically switched into a recoverable processing mode of operation. The recoverable processing mode of operation is a mode in which hardware error recovery resources, including at least one of the hardware error recovery resources in the subset, are purposed for hardware error recovery operations.

  • Publication number: 20130091335
    Abstract: A computer-implemented method, computer program product and data processing system provide checkpoint high-available for an application in a virtualized environment with reduced network demands. An application executes on a primary host machine comprising a first virtual machine. A virtualization module receives a designation from the application of a portion of the memory of the first virtual machine as purgeable memory, wherein the purgeable memory can be reconstructed by the application when the purgeable memory is unavailable. Changes are tracked to a processor state and to a remaining portion that is not purgeable memory and the changes are periodically forwarded at checkpoints to a secondary host machine. In response to an occurrence of a failure condition on the first virtual machine, the secondary host machine is signaled to continue execution of the application by using the forwarded changes to the remaining portion of the memory and by reconstructing the purgeable memory.

  • Publication number: 20120297236
    Abstract: In one embodiment, a method attempts, by a computing device, to determine a placement of a set of virtual machines on available hosts upon failure of a host. The placement considers the set of virtual machines as being not powered on any of the available hosts. The method further determines, by the computing device, a placed list of virtual machines in the set of virtual machines as a recommendation to power on to the available hosts. The determination of the placed list of virtual machines is used to determine a power off list of virtual machines in the set of virtual machines to power off, wherein virtual machines in the power off list of virtual machines are currently powered on available hosts but were considered to be powered off to determine the placement.

  • Patent number: 8271754
    Abstract: A system, method and computer-usable medium are disclosed for recovering data from a memory storage device. The operating system (OS) of an IPS comprising a source memory storage device, further comprising stored data, is monitored to detect a defective operating state. If a defective operating state of the OS is detected, then operation of the IPS is terminated, followed by the initiation of IPS boot operations to recover data from the source memory storage device. The OS is bypassed, and initial boot operations are performed from a management controller or from the BIOS of the IPS. Additional boot operations are performed, and once the IPS has been brought to an operative state, a data recovery module is used to transfer data from the source memory storage device to a target storage device.

  • Publication number: 20120144259
    Abstract: By utilizing Reed-Solomon erasure decoding algorithms and techniques, the system is able to perform error detection for the case where the number of bytes received in error exceeds a correcting capability of a decoder. The error detection can be used, for example, to determine whether a codeword is decodable, and whether the retransmission of data is necessary. The retransmission can be accomplished by assembling a message that is sent to another modem requesting retransmission of one or more portions of data, such as one or more codewords.

  • Publication number: 20100017643
    Abstract: Provided is a failover method for a cluster system for realizing smooth failover of the guest OS's, even when there are many guest OS's, while reducing consumption of computer resources of a server. Smooth failover is realized by preventing competition during failover even when the number of guest OS's is increased. In a cluster configuration in which a slave/master cluster program is operated in a guest OS/host OS, the master cluster program (510) collects and transmits heartbeats of the slave cluster program, thereby realizing failure monitoring through the certain amount of heartbeats without depending on the number of guest OS's. Further, when the master cluster program monitors failures of the slave cluster program of its own computer to find a normal operation of the guest OS, the amount of communication through heartbeats is reduced by eliminating the necessity of communication to a standby system slave cluster program.

  • Publication number: 20090024820
    Abstract: A method and module for performing a crash dump in a data processing apparatus in which memory for running the crash dump routine is allocated at the time of the crash. The method comprises running a first routine to identify memory locations of data for use by a second routine; allocating memory for performing the second routine from a memory range that does not contain the identified memory locations; and running the second routine using the allocated memory, wherein the first routine comprises a dummy crash dump routine and the second routine comprises a crash dump routine. The dummy crash dump may use smaller data sizes and does not perform any input or output to non-volatile storage of the data to be dumped. When a memory range that is safe to be reused has been identified, the data stored therein can be dumped and then memory for performing the actual crash dump routine can be allocated from the memory range and be reused for performing the actual crash dump routine.
