Abstract: Methods and systems that provide ways to detect the hydrocarbon flow while eliminating the hydrogen darkening effect in the downhole environment by separated strain and temperature measurement. The methods and systems use fiber optic sensing cables for real-time detection of hydrocarbon fluids (oil, gas, condensate or combination) in oil and gas wells, for example in cemented annuli between either a rock formation and a casing string, or between a larger diameter casing string and a smaller diameter casing string, or in a cement plug left in the well upon abandonment. Hydrogen darkening-resistant temperature and strain sensing fiber optic cables can be used in conjunction with hydrocarbon sensitive polymers to monitor hydrocarbon migration in the oil and gas well and/or to identify the zone(s) from which the hydrocarbons are flowing.

Abstract: A method of synchronizing thread execution of a host and one or more coprocessors includes writing by the host of an event command and at least one coprocessor instruction to a FIFO and comparing of the event command with a current event register of the coprocessor until they match, whereupon the FIFO entries are popped and the instructions are forwarded to the coprocessor for execution. A plurality of entry groups can be written to the FIFO, each beginning with an event command. The instructions can direct the coprocessor to exchange data with shared memory and apply its thread to the received data. The processors and shared memory can be linked by a ring-type bus having a controller that performs the comparison, popping, and instruction forwarding. The coprocessor clears the current event register during thread execution, and then writes an event command to the register when processing is complete.

Abstract: Techniques provide for specifying priorities and thresholds used for cache promotion and flushing on a per pool basis. The thresholds may include a promotion threshold and a flushing threshold. The promotion threshold is used to determine whether data portions of the pool are promoted to a secondary cache. The flushing threshold is used to determine whether any data portions of the pool currently stored in the secondary cache are flushed to non-volatile physical storage. Each of the promotion threshold and the flushing threshold for the pool may be determined in accordance with the priority specified for the pool. For remaining data portions that are included in a pool for which a pool specific priority is not specified, a default technique may be used, for example, which uses the same promotion threshold and the same flushing threshold for all pools for which a pool specific priority is not specified.
