System and method for synchronizing execution of a batch of threads

A method for creating a computer program to be executed by a plurality of threads, in which the method utilizes a technique for execution synchronization referred to herein as a batch synchronization section. According to this technique, a plurality of threads may be associated with one another as a “batch” of threads. Each thread in the plurality (batch) of threads may execute the computer program simultaneously. The batch synchronization section may specify a portion of the computer program for which the execution of the portion by the plurality of threads is to be synchronized. In one embodiment different types of batch synchronization sections may be specified, wherein each type of batch synchronization section performs a different type of execution synchronization. In one embodiment the method may enable execution synchronization behavior for multiple concurrent executions of a test executive test sequence to be specified. The test sequence may include one or more batch synchronization sections. Multiple threads may each execute an instance of the test sequence to concurrently to test a group of units under test, and the batch synchronization sections may coordinate the execution of the multiple threads where necessary.

Positive electrode for nonaqueous electrolyte secondary battery, and production method thereof

A positive electrode for a nonaqueous electrolyte secondary battery using a positive electrode active material mixture according to an embodiment of the invention includes a positive electrode active material capable of intercalating and deintercalating a lithium ion, a conductive agent and a binder, in which the positive electrode active material is produced by coating cobalt-based lithium composite oxide represented by a general formula: LiaCo1-sM1sO2 with lithium nickel cobalt manganese oxide represented by a general formula: LibNitCouMnvO2, the ratio r1 / r2 of the average particle diameter r1 of the cobalt-based lithium composite oxide and the average particle diameter r2 of the lithium nickel cobalt manganese oxide is 2≦r1 / r2≦50, and the average particle diameter r2 of the lithium nickel cobalt manganese oxide is 0.5 μm≦r2≦20 μm. By containing such a constitution, a positive electrode for a nonaqueous electrolyte secondary battery in which even when the charging discharging is repeated at a high potential of 4.5 V based on lithium, not only is the retention characteristics in a charged state excellent, but also the enhancing the capacity and the energy density of the battery can be achieved; and a production method thereof, can be provided.
