Hardware Exerciser Having Variable-Length Runtime

A computer system, comprising:

• a processor set;
• one or more computer-readable storage media;
• and
• program instructions stored on the one or more storage media to cause the processor set to perform operations comprising:
• initiating, by a hardware exerciser, a microprocessor to iteratively perform a plurality of runs of a first test case;
• for each of the plurality of runs of the first test case, determining at least a first performance metric indicating a respective performance of the microprocessor for the respective run of the first test case;
• responsive to completion of each of the plurality of respective runs of the first test case subsequent to a first run of the first test case, determining a difference between the at least the first performance metric determined for a most recent run of the first test case and the at least the first performance metric determined for a previous run of the first test case;
• and
• for a first most recent run of the first test case, responsive to the difference, between the at least the first performance metric determined for the first most recent run of the first test case and the at least the first performance metric determined for a first previous run of the first test case, being greater than a first threshold value, continuing running the first test case on the microprocessor.

A computer program product for variable-length runtime for a hardware exerciser, the computer program product comprising:

• one or more computer-readable storage media;
• and
• program instructions stored on the one or more storage media to perform operations comprising:
• initiating, by the hardware exerciser, a microprocessor to iteratively perform a plurality of runs of a first test case;
• for each of the plurality of runs of the first test case, determining at least a first performance metric indicating a respective performance of the microprocessor for the respective run of the first test case;
• responsive to completion of each of the plurality of respective runs of the first test case subsequent to a first run of the first test case, determining a difference between the at least the first performance metric determined for a most recent run of the first test case and the at least the first performance metric determined for a previous run of the first test case;
• and
• for a first most recent run of the first test case, responsive to the difference, between the at least the first performance metric determined for the first most recent run of the first test case and the at least the first performance metric determined for a first previous run of the first test case, being greater than a first threshold value, continuing running the first test case on the microprocessor.
