Aufspürung von heissen Stellen in einer Maschine mit nichtuniformen Speicherzugriffen

摘要

The machine has a non-uniform access memory and an ante-memory coherence, and consists of several modules, each consisting of a monitor (6) for ensuring a coherence of data with the other modules of the machine. The monitor has one register (101) to hold a physical address in the memory, and another register (102) containing a second physical address in the memory. A further monitor (111,121,108) monitors the amount of activity relative to the addresses lying between the first and second physical addresses. A third register (109) contains a threshold value for measuring the quantity of activity. A comparator (122) for detecting when the quantity of activity measured passes through the given threshold.
