Unified, workload-optimized, adaptive RAS for hybrid systems

摘要

A method, system, and computer program product for maintaining reliability in a computer system. In an example embodiment, the method includes managing workloads on a first processor with a first processor architecture by an agent process executing on a second processor with a second processor architecture. The method proceeds by activating redundant computation on the second processor by the agent process. The method continues by performing a same computation from a workload of the workloads at least twice. Finally, the method includes comparing results of the same computation. In this embodiment the first processor is coupled the second processor by a network, and the first processor architecture and second processor architecture are different architectures.

主权项

1. A system comprising:
a first processor; a first memory coupled to the first processor; a network link coupled to the first processor; a second processor coupled to the first processor through the network link; a second memory coupled to the second processor, the second memory having computer readable program code embodied therewith, the computer readable program code configured to:
set a flag for redundancy checking of a computation in the second memory, where the redundancy checking performs the computation at least twice and compares results of each computation; andcommand an agent process executing on the first processor to perform redundancy checking when running the computation on the first processor based on a state of the flag.
