Methods and systems for testing components of parallel computing devices

A method of testing a first computer device of a vehicle, the method comprising:

• selecting an operational component of the first computer device, wherein the operational component is one of a memory component, a register, and an Arithmetic Logic Unit (ALU);
• selecting a test operation that is configured to utilize an entire capacity of the operational component, wherein selecting the test operation includes:
• selecting a write operation and a read operation as the test operation in response to the operational component being the memory component,
• selecting a bit shift operation as the test operation in response to the operational component being the register,
• selecting one of a vector addition operation, a vector multiplication operation, or a logic operation in response to the operational component being the ALU;
• instructing the first computer device to perform the test operation and to generate a first result;
• instructing a second computer device of the vehicle to perform the test operation and generate a second result;
• comparing the first result of the test operation from the first computer device with the second result based on a functional correctness of the first computer device;
• and
• indicating that the first computer device is faulty based at least in part on a difference between the first result and the second result.

A system for testing a computer device of a vehicle, the system comprising:

• at least one processor configured for:
• selecting an operational component of the first computer device;
• selecting a test operation that is configured to utilize an entire capacity of the operational component;
• instructing the first computer device to perform the test operation and to generate a first result;
• retrieving a second result of the test operation;
• comparing the first result of the test operation from the first computer device with the second result;
• and
• indicating that the first computer device is faulty based at least in part on a difference between the first result and the second result.
