Abstract

Computer-implemented methods for workload management and related computer program products are disclosed. One method comprises receiving corrosion rate signals from a first sensor associated with a first compute node, determining a first corrosion level for the first compute node as a function of the corrosion rate signal received from the first sensor, and automatically removing a first workload from the first compute node in response to determining that the first compute node has a first corrosion level that is greater than a setpoint level of corrosion.
