Fault detection

A system comprising:

• a memory;
• and
• a processing device comprising one or more processors, the one or more processors configured to perform operations comprising:
• receiving a request to initiate a testing process for each of a plurality of processing units, a first processing unit of the plurality of processing units including a first virtual processor executing a first set of operations and a second processing unit of the plurality of processing units including a second virtual processor executing a second set of operations;
• causing execution of the first set of operations to be transferred from the first virtual processor to the second virtual processor by updating a first operation queue of the second virtual processor to include execution state data associated with at least one operation of the first set of operations that was executed by the first virtual processor;
• initiating execution of the testing process at the first processing unit while the second virtual processor running on the second processing unit executes;
• 'the first set of operations in accordance with the execution state data, and
• the second set of operations;
• responsive to detecting that the execution of the testing process is completed at the first processing unit, causing execution of the first set of operations and the second set of operations to be transferred from the second virtual processor to the first virtual processor by updating a second operation queue of the first virtual processor to include execution state data associated with at least one of an operation of the first set of operations or an operation of the second set of operations that was executed by the second virtual processor;
• and
• initiating execution of the testing process at the second processing unit while the first virtual processor running on the first processing unit executes the first set of operations and the second set of operations.

A processor comprising:

• a plurality of processing units;
• and
• a controller to:
• receive a request to initiate a testing process for each of a plurality of processing units, a first processing unit of the plurality of processing units including a first virtual processor executing a first set of operations and a second processing unit of the plurality of processing units including a second virtual processor executing a second set of operations;
• cause execution of the first set of operations to be transferred from the first virtual processor to the second virtual processor by updating a first operation queue of the second virtual processor to include execution state data associated with at least one operation of the first set of operations that was executed by the first virtual processor;
• initiate execution of the testing process at the first processing unit while the second virtual processor running on the second processing unit executes:
• the first set of operations in accordance with the execution state data, and
• the second set of operations;
• responsive to detecting that the execution of the testing process is completed at the first processing unit, cause execution of the first set of operations and the second set of operations to be transferred from the second virtual processor to the first virtual processor by updating a second operation queue of the first virtual processor to include execution state data associated with at least one of an operation of the first set of operations or an operation of the second set of operations that was executed by the second virtual processor;
• and
• initiate execution of the testing process at the second processing unit while the first virtual processor running on the first processing unit executes the first set of operations and the second set of operations.
