Verification of dynamic logical partitioning

摘要

Embodiments of the present invention disclose a method, computer program product, and system for verifying transitions between logical partition configurations. A computer system divides the physical resources of a processing core into logical partitions, each of which has at least one processing subcore. The computer system loads the contexts of the logical partitions and assigns test cases to each processing subcore. The processing subcore executes the test case, verifying the context of the logical partition. The computer system reassigns the test cases to different processing cores in anticipation of reconfiguring the number of logical partitions on the processing core. The computing system reconfigures the number of logical partitions on the processing core and executes the test cases as assigned on the reconfigured logical partitions. (124 words)

主权项

1. A non-transitory computer readable storage medium for verifying transitions between logical partition configurations, the computer program product comprising:
one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising: program instructions to divide physical resources of a processing core into a number of logical partitions, wherein each logical partition has associated context comprising at least one processing subcore; program instructions to assign a test case to each processing subcore, wherein each assigned test case contains instructions for verifying the associated context of the respective logical partition to which the processing subcore belongs, and execute the assigned test cases; program instructions to reassign at least some of the test cases to different processing subcores prior to reconfiguring the physical resources of the processing core into a different number of logical partitions; program instructions to reconfigure the physical resources into the different number of logical partitions; and program instructions to execute the test cases as assigned within the different number of logical partitions.
