US 8,788,871 B2 · Unified, workload-optimized, adaptive RAS for hybrid systems

Abstract

A method, system, and computer program product for maintaining reliability in a computer system. In an example embodiment, the method includes performing a first data computation by a first set of processors, the first set of processors having a first computer processor architecture. The method continues by performing a second data computation by a second processor coupled to the first set of processors, the second processor having a second computer processor architecture, the first computer processor architecture being different than the second computer processor architecture. Finally, the method includes dynamically allocating computational resources of the first set of processors and the second processor based on at least one metric while the first set of processors and the second processor are in operation such that the accuracy and processing speed of the first data computation and the second data computation are optimized.

Dependent claims

A system for maintaining reliability, the 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, the second processor having at different processor architecture than the first processor;
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 a computation for redundancy checking in the first memory, the redundancy checking comparing a redundant computation by the first processor and the second processor;
and
