摘要： A method for selective duplication of subtasks in a high-performance computing system includes: monitoring a health status of one or more nodes in a high-performance computing system, where one or more subtasks of a parallel task execute on the one or more nodes; identifying one or more nodes as having a likelihood of failure which exceeds a first prescribed threshold; selectively duplicating the one or more subtasks that execute on the one or more nodes having a likelihood of failure which exceeds the first prescribed threshold; and notifying a messaging library that one or more subtasks were duplicated.

摘要： A method for providing selective memory error protection responsive to a predictable failure notification associated with at least one portion of a memory in a computing system includes: obtaining an active error correcting code (ECC) configuration corresponding to the portion of the memory; determining whether the active ECC configuration is sufficient to correct at least one error in the portion of the memory affected by the predictable failure notification; when the active ECC configuration is insufficient to correct the error, determining whether data corruption can be tolerated by an application running on the computing system; when data corruption cannot be tolerated by the application, determining whether a stronger ECC level is available and, if a stronger ECC level is available, increasing a strength of the active ECC configuration; and when data corruption can be tolerated, performing page reassignment and aggregation of non-critical data.

摘要： According to one embodiment, a method for thread consolidation is provided for a system that includes an operating system and a multi-core processing chip in communication with an accelerator chip. The method includes running an application having software threads on the operating system, mapping the software threads to physical cores in the multi-core processing chip, identifying one or more idle hardware threads in the multi-core processing chip and identifying one or more idle accelerator units in the accelerator chip. The method also includes executing the software threads on the physical cores and the accelerator unit. The method also includes the controller module consolidating the software threads executing on the physical cores, resulting in one or more idle physical cores and a consolidated physical core. The method also includes the controller module activating a power savings mode for the one or more idle physical cores.
