  • Experimental design and statistical modeling tool for workload characterization
    Patent number: 7103517
    Abstract: A method for a cache architecture simulation includes obtaining a first sample set for the cache architecture using a non-stationary Gaussian field model, performing a cache architecture simulation using the first sample set to produce a first set of simulation data, and fitting a first multivariate model to the first set of simulation data.
    Type: Grant
    Filed: July 3, 2002
    Date of Patent: September 5, 2006
    Assignee: Sun Microsystems, Inc.
    Inventors: Ilya Gluhovsky, Brian W. O'Krafka
  • Modeling overlapping of memory references in a queueing system model
    Patent number: 7054874
    Abstract: One embodiment of the present invention provides a system that facilitates modeling the effects of overlapping of memory references in a queueing system model. The system receives a memory reference during execution of a queueing system model. Upon receiving the memory reference, the system determines if the memory reference generates a cache miss. If so, the system models the cache miss in a manner that accounts for possible overlapping of the cache miss with other memory references and other processor operations.
