Abstract
A system and method for optimizing redundant output verification, are provided. A hardware-based store fingerprint buffer receives multiple instances of output from multiple instances of computation. The store fingerprint buffer generates a signature from the content included in the multiple instances of output. When a barrier is reached, the store fingerprint buffer uses the signature to verify the content is error-free.
Claims22
A system, comprising:
- a hardware-based store fingerprint buffer installed in an electronic circuit that processes data in parallel and configured to perform operations comprising:
- receiving a first instance of output associated with a first instance of computation;
- receiving a second instance of output associated with a second instance of computation, wherein the first and second instances of the computation are part of a workgroup adapted for parallel execution;
- generating a signature from content included in the first instance of output and the second instance of output;
- and
- verifying, using the signature, that the content is error-free.
