摘要： The present invention extends to methods, systems, and computer program products for reconstructing program control flow. Embodiments include implementing or morphing a control flow graph (“CFG”) into an arbitrary loop structure to reconstruct (preserve) control flow from original source code. Loop structures can be optimized and can adhere to target platform constraints. In some embodiments, C++ source code (a first higher level format) is translated into a CFG (a lower level format). The CFG is then translated into HLSL source code (a second different higher level format) for subsequent compilation into SLSL bytecode (that can then be executed at a Graphical Processing Unit (“GPU”)). The control flow from the C++ source code is preserved in the HLSL source code.

摘要： The present invention extends to methods, systems, and computer program products for emulating pointers. Pointers can be emulated by replacing the pointers with a pair and replacing each dereference site with a switch on the tag and a switch body that executes the emulated pointer access on the corresponding variable the pointer points to. Data flow optimizations can be used to reduce the number of switches and/or reduce the number of cases which need be considered at each emulated pointer access sites.

摘要： A computer-implemented method, computer-readable media, and a computerized system to track and detect data hazards are provided. The computerized system includes processors configured to execute instructions associated with a multithreaded program. The computerized system allocates memory for the multithreaded program and creates threads for execution on the processors. The memory may include a reserved area for tracking information. The threads access the allocated memory in accordance with the multithreaded program and the memory including the tracking information is updated based on the threads' memory access. In turn, the processors generate notifications of data hazard based on the tracking information stored in the allocated memory.

摘要： The debugging of a program in a data parallel environment. A connection is established between a debugging module and a process of the data parallel environment. The connection causes the data parallel environment to notify the debugging module of certain events as they occur in the execution of the process. Upon notification of such an event, the process execution is paused, and the debugging module may query the data parallel environment for information regarding the process at the device independent virtual machine layer. Upon completion of this querying, the process may then resume execution. This may occur repeatedly if multiple events are encountered.
