Abstract: A method and computer program product for error monitoring partitions in a computer system. A partition status buffer (PSB) denotes a status (GOOD, BAD, NOCARE) of each partition of at least two partitions. The BAD status denotes that the partition has encountered at least one error that is currently unrepaired. A global supervisor mapping (GSM) associates each partition (designated as a supervised partition) with a supervisor partition in a one-to-one mapping. The supervisor partition determines its supervised partition from the GSM and ascertains the status of its supervised partition from the PSB. If the status of the supervised partition is BAD then the supervisor partition performs a recovery procedure. The recovery procedure: obtains a grant of access to physical and logical resources of the supervised partition which contains error data of the supervised partition; gathers the error data; sets the status of the supervised partition to the NOCARE status.

Abstract: In a non-volatile memory unit such as a flash memory unit, the degradation of charge can result in an error during a read operation. By using the error checking and correction techniques, a determination can be made whether a detected error can be corrected and, if correctable, is the consistent with charge degradation at that bit position displaying the error. When a correctable error is detected, the signal group address and the correction pattern are stored and an interrupt request flag applied to the central processing unit. When the interrupt flag is processed, the central processing unit, using the signal group address and the correction pattern, restores the charge of the bit position in the memory unit. In this manner, further read operations involving the restored bit position will not repeat the corrected error.

Abstract: A mechanism is provided for accessing, by an application running on a first processor, operating system services from an operating system running on a second processor by performing an assisted call. A data plane processor first constructs a parameter area based on the input and output parameters for the function that requires control processor assistance. The current values for the input parameters are copied into the parameter area. An assisted call message is generated based on a combination of a pointer to the parameter area and a specific library function opcode for the library function that is being called. The assisted call message is placed into the processor's stack immediately following a stop-and-signal instruction. The control plane processor is signaled to perform the library function corresponding to the opcode on behalf of the data plane processor by executing a stop and signal instruction.

A data collating part collates the data sent from the sending part with a data generated by the first device, and determines that it is abnormal when a mismatch between these data occurs. Thus, a data generated by the first device is collated with a data generated by the second device and when a mismatch between these data occurs, it is determined that it is abnormal, so that abnormality can be detected surely.

Abstract: An electronic control system mounted on an automobile, such as a motor-assisted power steering system, includes a commanding unit for calculating a command value and a driving unit for driving an actuator according to the command value. The commanding unit and the driving unit are communicably connected to each other through a communication bus. The command value is calculated in response to an order to calculate sent from the driving unit and is transmitted to the driving unit. The driving unit detects abnormality or malfunction in the commanding unit by comparing the transmitted command value with data pre-stored in the driving unit. If a command value sent from one of the commanding units is found to be incorrect, the actuator is driven without using the incorrect command value.

Abstract: Data in a storage medium is scanned while a storage device is in an idle state. A proportion of scanned data in entire data in the storage medium is compared with a threshold value. If the proportion of the scanned data is less than the threshold value, an unscanned data in the storage medium is scanned during a time interval between commands received by the storage device from outside. The process is repeated until the proportion of the scanned data is equal to or more than the threshold value.

Abstract: In a pipelined processor where instructions are pre-decoded prior to being stored in a cache, an incorrectly pre-decoded instruction is detected during execution in the pipeline. The corresponding instruction is invalidated in the cache, and the instruction is forced to evaluate as a branch instruction. In particular, the branch instruction is evaluated as “mispredicted not taken” with a branch target address of the incorrectly pre-decoded instruction's address. This, with the invalidated cache line, causes the incorrectly pre-decoded instruction to be re-fetched from memory with a precise address. The re-fetched instruction is then correctly pre-decoded, written to the cache, and executed.

Abstract: A program managing method in a web service system for providing a web service for testing a message which has been changed in response to a change made in interface definition information comprises steps for judging as to whether or not an error occurs when an access request made by a message is transmitted, which is caused by the change of the interface definition information indicative of an interface of a destination of the access request; changing the message in correspondence with a content of the changed interface definition information in the case that the error occurs which is caused by the change of the interface definition information; and transmitting an access request made by the changed message in a test mode. It then becomes possible to correct and test the program in a dynamic manner for preventing recurrence of this error.

After recovery from the error condition, the sequencer is reprogrammed to operate normally.

Abstract: Mechanisms for efficiently restoring one or more memory blocks of a primary computing system. In order to restore a backup memory block, the primary system accesses transformed data that represents a result of a deterministic many-to-one mapping function, such as a hash function, applied to the backup memory block. The primary computing system also accesses transformed data that represents a result of the deterministic many-to-one mapping function applied to a corresponding primary memory block as the memory block exists on the primary system. The primary transformed data and the backup transformed data are then compared. If the primary and backup transformed data are different, the corresponding primary and backup memory blocks are also different. Accordingly, the primary computing system requests the full memory block from the backup computing system.

Operator logs can be used to label each upset with a characteristic cause and/or recovery technique.

Abstract: Briefly, according to the invention in an information processing system including a plurality of information processing nodes, a request for checkpointing by an application includes node health criteria (or parameters). The system has the authority to grant or deny the checkpointing request depending on the system health or availability. This scheme significantly improves not only the system performance, but also the application running time as the system. By skipping a checkpoint the application can use the same time to run the application instead of spending extra time for checkpointing.

Abstract: Methods and apparatus are described for evaluating a binary classification system operable to classify each of a plurality of events as a first event type or a second event type. At least some of the events of the first event type are independently verifiable with reference to verification data. The binary classification system is susceptible to a first error type in which events of the first event type are classified as the second event type, and a second error type in which events of the second event type are classified as the first event type. Operation of a first configuration of the binary classification system is evaluated with reference to an objective function. The objective function is derived by expressing a number of errors of the second error type in terms of a number of errors of the first error type with reference to the verification data, and by assuming relative proportions of the first and second event types within the plurality of events.
