Abstract: A checking system is described for determining whether a component is thread safe in the course of interacting with two or threads in a client environment. The checking system uses a manual, automatic, or semi-automatic technique to generate a test. The checking system then defines a set of coarse-grained observations for the test, in which the component is assumed to exhibit linearizability when interacting with threads. The set of coarse-grained observations may include both complete and “stuck” histories. The checking system then generates a set of fine-grained observations for the tests; here, the checking system makes no assumptions as to the linearizability of the component. The checking system identifies potential linearizability errors as those entries in the set of fine-grained observations that have no counterpart entries in the set of coarse-grained observations. The checking system may rely on a stateless model checking module to perform its functions.

Abstract: The present invention provides for a system and method of discovering whether a medical device is connected to a network, establishing secure communications between and a server and the medical device, and communicating with the medical device. Also disclosed is a method of encryption to ensure secure communications within the network between a server and medical devices connected to the network. The invention also includes a system and method for determining the location of medical devices within an institution.

Abstract: A software transactional memory (STM) test generator is provided that converts existing test code into test code that tests the functionality of an STM system. To generate the STM test code, the generator inserts transactional semantics into the existing test code and replaces any methods of the test code that are not supported by an STM system. The STM test code is compiled and executed to generate an STM test output, and the STM test output is compared to the output of the existing test code to produce STM test results.
