Generating and executing test cases for core performance verification

A computer system for generating and executing a test case for performance verification of a computing system comprising:

• one or more memories;
• and
• at least one processor coupled to the one or more memories and configured to:
• receive a trace collected during flow of instructions through an execution pipeline of one or more processors, wherein the trace includes contents of registers and memory;
• determine from the trace one or more memory locations to be reset based on behavior of the instructions indicated within the trace;
• generate the test case including indications of the one or more memory locations to be reset and corresponding contents for resetting the one or more memory locations;
• and
• execute the test case on one or more platforms a plurality of times to determine a performance measurement and reset the one or more memory locations with the corresponding contents between executions of the test case on the one or more platforms.

A computer program product for generating and executing a test case for performance verification of a computing system, the computer program product comprising one or more computer readable storage media having program instructions collectively stored on the one or more computer readable storage media, the program instructions executable by at least one processor to cause the at least one processor to:

• receive a trace collected during flow of instructions through an execution pipeline of one or more processors, wherein the trace includes contents of registers and memory;
• determine from the trace one or more memory locations to be reset based on behavior of the instructions indicated within the trace;
• generate the test case including indications of the one or more memory locations to be reset and corresponding contents for resetting the one or more memory locations;
• and
• execute the test case on one or more platforms a plurality of times to determine a performance measurement and reset the one or more memory locations with the corresponding contents between executions of the test case on the one or more platforms.
