Code restructuring or reordering based on profiling information and memory hierarchy is provided by constructing a Program Execution Graph (PEG) corresponding to a level of the memory hierarchy, partitioning this PEG to reduce estimated memory overhead costs below an upper bound, and constructing a PEG for a next level of the memory hierarchy from the partitioned PEG. The PEG is constructed from control flow and frequency information from a profile of the program to be restructured. The PEG is a weighted undirected graph comprising nodes representing basic blocks and edges representing transfer of control between pairs of basic blocks. The weight of a node is the size of the basic block it represents and the weight of an edge is the frequency of transition between the pair of basic blocs it connects.

The communicated code can be reconstructed by the system into an identical gem image, enabling remote discussion and evaluation of the same target gem, including matching and pairing of gems. A practical embodiment of the grading system and method is described, including application modes specifically aimed at gems and diamonds.

RFID systems, devices, software and methods are adapted for receiving from an RFID tag at least waves that communicate at least a first version of its code. An output tag code is output that is the same as the first version, if a fidelity criterion is met regarding the first version. If not met, the output tag code is instead a final version that is reconstructed from the first version, and also from any additionally optionally subsequently received versions. In some embodiments, an error recovery block includes a subcomponent fidelity criterion checking block that can determine whether the fidelity criterion is met, and a code reconstruction block that can derive the final version.

Automated refactorings as implemented in modern IDEs for Java usually make no special provisions for concurrent code. Thus, refactored programs may exhibit unexpected new concurrent behaviors. We analyze the types of such behavioral changes caused by current refactoring engines and develop techniques to make them behavior-preserving, ranging from simple techniques to deal with concurrency-related language constructs to a framework that computes and tracks synchronization dependencies. By basing our development directly on the Java Memory Model we can state and prove precise correctness results about refactoring concurrent programs. We show that a broad range of refactorings are not influenced by concurrency at all, whereas other important refactorings can be made behavior-preserving for correctly synchronized programs by using our framework. Experience with a prototype implementation shows that our techniques are easy to implement and require only minimal changes to existing refactoring engines.
