Abstract: A technique for adjusting a prefetching rate. More particularly, embodiments of the invention relate to a technique to adjust prefetching as a function of the usefulness of the prefetched data.

Abstract: A technique for using memory attributes to relay information to a program or other agent. More particularly, embodiments of the invention relate to using memory attribute bits to check various memory properties in an efficient manner.

Abstract: A method and apparatus for hardware-based dynamic escape detection in managed run-time environments are described. In one embodiment, the method includes the detection of a pointer update of a first object having a global scope. In one embodiment, a single instruction is issued to assert that a scope attribute associated with a target object of the pointer update identifies a global scope. The single instruction may return failure if the scope attribute that is associated with the second object identifies the scope of the second object as local. Verification may include the reading of an object descriptor for the second object to determine whether a scope attribute of the object descriptor indicates that the scope of the second object is local. Once verified, in one embodiment, the second object, and each object reachable from the second object, are converted into global objects. Other embodiments are described and claimed.
