We will be designing concurrent data structures in both Java and C/++. Each student/group will be taking a concurrent data structure (most will be from the book "The art of multiprocessor programming" and related papers") and will create C/++ and Java versions, then test them on a new Sun 128 way multiprocessor machine we have just received using a set of benchmarks we will provide. The results will then be published in a specific web form that we will supply and will be part of a library that we will most likely make available to other programmers.
