Abstract: A method for initializing a chip includes turning on a direct current power supply of the chip and transmitting an acknowledge signal after turning on the direct current power supply of the chip. Whether the acknowledge signal is received by a control device during a predetermined time interval is determined. If the acknowledge signal is not received by the control device, the acknowledge signal is regarded as an abnormal signal. If the acknowledge signal is abnormal, turn off the direct current power supply of the chip. After turning off the direct current power supply, change a voltage of a reset pin of the chip. After changing the voltage of the reset pin of the chip, turn on the direct current power supply of the chip again.

Abstract: Techniques are described for managing access of executing programs to non-local block data storage. In some situations, a block data storage service uses multiple server storage systems to reliably store copies of network-accessible block data storage volumes that may be used by programs executing on other physical computing systems, and snapshot copies of some volumes may also be stored (e.g., on remote archival storage systems). A group of multiple server block data storage systems that store block data volumes may in some situations be co-located at a data center, and programs that use volumes stored there may execute on other computing systems at that data center, while the archival storage systems may be located outside the data center. The snapshot copies of volumes may be used in various ways, including to allow users to obtain their own copies of other users' volumes (e.g., for a fee).

In response to a request to restore the data processing system, the identified files on the sorted index list are restored in magnetic tape identification and magnetic tape location sort order. Operation of the restored data processing system is then begun in accordance with the restored files.

Abstract: A host swap hypervisor provides a high availability hypervisor for virtual machines on a physical host computer during a failure of a primary hypervisor on the physical host computer. The host swap hypervisor resides on the physical host computer that runs the primary hypervisor, and monitors failure indicators of the primary hypervisor. When the failure indicators exceed a threshold, the host swap hypervisor is then autonomically swapped to become the primary hypervisor on the physical host computer. The original primary hypervisor may then be re-initialized as the new host swap hypervisor.

Abstract: A system and method of using a baseboard management controller (BMC) to detect a fault on a communication bus. The BMC is connected to and monitors the operation of the communication bus. The BMC automatically detects a communication bus hang and reports bus hang to the host. The BMC attempts to access the communication bus. If the BMC can access the communication bus, the BMC then resets all of the devices connected to the communication bus. The BMC then attempts to contact components connected to the devices. If a component is not accessible via its communication device, the BMC blocks the channel used by the component and reports that information. Once the BMC detects that the component has been removed, the BMC attempts to recover the channel via the I2C/SM bus for use by the computer network.

Abstract: A hardware-assisted mechanism may improve the performance of memory reclamation operations that employ hazard pointers. The mechanism includes hazard lookaside buffers (HLBs), each implemented in hardware and locally accessible to one or more processor cores, and two new instructions. A special store instruction may write entries to local HLBs for pointers that have been or will be dereferenced but were not yet written to a shared hazard table (which requires memory barriers). Each entry may include a hazard pointer and a table address. A special test instruction may signal each HLB to determine whether it contains a particular pointer and, if so, to return a response. If the pointer does not reside in any HLB, the memory reclamation operation may search the hazard table for the pointer. If the pointer is found in an HLB or in the hazard table, the pointed-to memory location or memory block is not reclaimed.
