摘要： A deadlock detection method and computer system for parallel programs. A determination is made that a lock of the parallel programs is no longer used in a running procedure of the parallel programs. A node corresponding to the lock that is no longer used, and edges relating to the lock that is no longer used, are deleted from a lock graph corresponding to the running procedure of the parallel programs in order to acquire an updated lock graph. The lock graph is constructed according to a lock operation of the parallel programs. Deadlock detection is then performed on the updated lock graph.

摘要： A method and system for invoking Just-In-Time debugger is described, which can provide more efficient JIT debugging for complex code mixed applications. A method for invoking a Just-In-Time (JIT) debugger according to one embodiment includes checking a code type of a code address where a JIT debugging request is triggered from a process of a code-mixed application in response to the JIT debugging request from the process; acquiring corresponding JIT debugging information for different code types of the code-mixed application; and invoking a JIT debugger corresponding to the code type in response to the checked code type of the code address in the process and the acquired corresponding JIT debugging information.

摘要： A method and system for debugging a program in multithread environment which interrupts the running of a debuggee program begins by replacing the instruction at the position at which a breakpoint for debugging is desired to be set with a breakpoint instruction. When the breakpoint instruction is replaced back with the instruction at the position at which the breakpoint for debugging is set, an instruction is set in front of the breakpoint for debugging as a fence breakpoint; and when the instruction at the position at which the breakpoint for debugging is set, is replaced again with the breakpoint instruction. On completion, the fence breakpoint is replaced with the original instruction of the debuggee program at that position.

摘要： A method, computer program product and apparatus for indicating program modifications affecting program performance in an Integrated Development Environment (IDE). The modifications that a developer makes to a program is detected and the code location where these modifications occur is determined. The previous profiling data of the program is acquired. The effect of the modifications on the program performance according to the previous profiling data and the code location where the modifications occur is evaluated. The evaluation results may then be provided to the developer. As a result of the above process, the developer can be aware of the performance problem while he/she is editing the source code so as to make corrections without waiting after the profiling phase, thus greatly shortening the development period.
