Abstract: Provided are a method, system and article of manufacture, wherein a first application executes at least two threads corresponding to a simultaneous multi-threaded processor whose resources have been acquired by the first application. The at least two threads are synchronized before releasing the simultaneous multi-threaded processor to a second application.

Abstract: An apparatus for debugging source code includes a source code debugger configured to display state information and one or more initialization routines corresponding to a particular software function. The initialization routines initialize a target environment to a particular system state and facilitate replication, isolation, and analysis of software coding errors. In one embodiment, a function selector facilitates selection of the target function by a user and generates an execution request. In turn, a task dispatcher dispatches the initialization routines and associated software function in response to the execution request. The present invention greatly simplifies interactive debugging of source code.
