Scheduling workloads based on detected hardware errors

A data processing system for scheduling workloads based on detected hardware errors, the data processing system comprising:

• a bus system;
• a storage device connected to bus system, wherein the storage device stores computer usable program code;
• and
• a processor device connected to the bus system, wherein the processor device executes the computer usable program code to determine whether a hardware error is a cache error in response to determining that the hardware error is detected in hardware of the data processing system;
• determine whether execution of a workload on a processor is changing contents of a cache associated with the cache error more than a cache usage threshold value in response to determining that the hardware error is a cache error;
• determine whether the cache associated with the cache error is private to a particular core in the processor in response to determining that the execution of the workload on the processor is changing the contents of the cache associated with the cache error more than the cache usage threshold value;
• and schedule the execution of the workload on a different core of the processor so that the cache associated with the cache error that is private to the particular core is not used in response to determining that the cache associated with the cache error is private to the particular core in the processor.

A computer program product stored on a computer readable storage device having computer usable program code embodied thereon that is executable by a data processing system for scheduling workloads based on detected hardware errors, the computer program product comprising:

• computer usable program code for determining whether a hardware error is a cache error in response to determining that the hardware error is detected in hardware of the data processing system;
• computer usable program code for determining whether execution of a workload on a processor is changing contents of a cache associated with the cache error more than a cache usage threshold value in response to determining that the hardware error is a cache error;
• computer usable program code for determining whether the cache associated with the cache error is private to a particular core in the processor in response to determining that the execution of the workload on the processor is changing the contents of the cache associated with the cache error more than the cache usage threshold value;
• and
• computer usable program code for scheduling the execution of the workload on a different core of the processor so that the cache associated with the cache error that is private to the particular core is not used in response to determining that the cache associated with the cache error is private to the particular core in the processor.
