gdbsupports debugging programs with multiple threads (seeDebugging Programs with Multiple Threads). There are two modes of controlling execution of your program within the debugger. In the default mode, referred to asall-stop mode,when any thread in your program stops (for example, at a breakpoi...

Set a breakpoint at line 45, or at myfunction. The program will pause when it reaches the breakpoint. watch x == 3 Set a watchpoint, which pauses the program when a condition changes (when x == 3 changes). Watchpoints are great for certain inputs (myPtr != NULL) without having t...
Watchpoints:GDB can watch a variable and stop execution whenever it changes. This feature is useful when debugging programs where a variable is being modified unexpectedly. Backtracing:When a program crashes, GDB can show the function calls that led to the crash, known as a backtrace. This fea...
Using the Debugger 19 CUDA-GDB, Release 12.2 set cuda software_preemption on ▶ Export the following environment variable: CUDA_DEBUGGER_SOFTWARE_PREEMPTION=1 Either of the options above will activate software preemption. These options must be set prior to running the application. When the GPU ...

Those commands will be processed in order when CUDA-GDB is launched. 4.4. GUI Integration Emacs CUDA-GDB works with GUD in Emacs and XEmacs. No extra step is required other than pointing to the right binary. To use CUDA-GDB, the gud-gdb-command-name variable must be set to cuda-...
The program will pause when it reaches the breakpoint. watch x == 3 Sets a watchpoint, which pauses the program when a condition changes (when x == 3 changes). Watchpoints are great for certain inputs (myPtr != NULL) without having to break on every function call. continue Resumes ...
Running Valgrind from inside GDB has many advantages. GDB is an interactive program, but Valgrind is not. When debugging a program under GDB, you can stop a program, step through it, inspect the program state, and so on. When running a program under Valgrind, however, you get the diagnost...
