Title: Rob Joersz: Innovator in Cache Coherence Technology

Introduction

Rob Joersz is an accomplished inventor based in Portland, OR (US). He has made significant contributions to the field of cache coherence technology, holding a total of 2 patents. His work focuses on reducing latencies associated with cache coherence directory misses in shared distributed memory data processing systems.

Latest Patents

One of Rob Joersz's latest patents is titled "Prefetch miss indicator for cache coherence directory misses on external caches." This invention presents a system, method, and article of manufacture designed to minimize latencies linked to cache coherence directory misses. The technology evaluates a cache coherence directory for potential prefetching of a directory entry into a directory cache. If the prefetch evaluation results in a directory miss, a prefetch miss indicator is set. This indicator is then consulted during the processing of a memory block request corresponding to the directory entry. If the prefetch miss indicator is set, an accelerated snoop response action is initiated, thereby avoiding the latency of a second lookup into the cache coherence directory.
