Abstract

Official abstract text for this publication.

Cache miss rates for threads operating in a simultaneous multi-threading computer processing environment can be estimated. The single thread rates can be estimated by monitoring a shared directory for cache misses for a first thread. Memory access requests can be routed to metering cache directories associated with the particular thread. Single thread misses to the shared directory and single thread misses to the associated metering cache directory are monitored and a performance indication is determined by comparing the cache misses with the thread misses. The directory in the associated metering cache is rotated, and a second sharing performance indication is determined.

First claim

Opening claim text (preview).

1 - 7 . (canceled) 8 . A system for assessing cache miss rates for a plurality of threads operating in a simultaneous multi-threading computer processor system, the system comprising: at least one shared cache and shared cache directory with a set of rows that are shared by the plurality of threads; and, at least one processor configured to: monitor, based upon use of the shared cache directory by the plurality of threads, first shared cache misses indicated by memory a…
