Walk-Through Examples The chapter contains two CUDA-GDB walk-through examples: ▶ Example: bitreverse ▶ Example: autostep ▶ Example: MPI CUDA Application 13.1. Example: bitreverse This section presents a walk-through of CUDA-GDB by debugging a sample application–called bitre- verse–that...
To step through your program line by line, you can use the next or n command. $ (gdb) next $ (gdb) n Once you get to the function you want to work on, in the example above, the loopMe() function, you can step over it using the next command. This will skip function and go ...
Runs the program until next line, then pauses. If the current line is a function, it executes the entire function, then pauses. next is good for walking through your code quickly. step Runs the next instruction, not line. If the current instruction is setting a variable, it is the same...

These sections are automatically single-stepped through when the program is running, and any exception that occurs within these sections is precisely reported. Type 'help autostep' from CUDA-GDB for the syntax and usage of the command. Multiple Context Support On GPUs with compute capability of...
[Download RHEL 9 at no chargethrough the Red Hat Developer program. ] Skipping a function Yet another way to step into thebar,avoidingnum, is using theskipcommand: (gdb)b exmp.c:14 Breakpoint1at 0x401157:fileexmp.c, line14.(gdb)skip num ...
To start the program, execute the “run” command as seen in the below figure: run Once the program stops at the breakpoint, use the following commands to step through existing code: Example: Step Into a Function Call To step into a function call, use the “step” command. For example...
Solved: I'm getting this when I try to step through some of my code: I have extracted a small sample that reproduces the problem from my application.
What if the program isn't working?Basic ideaChances are if this is the case, you don't want to run the program without any stopping, breaking, etc. Otherwise, you'll just rush past the error and never find the root of the issue. So, you'll want to step through your code a bit ...
- `step`:进入函数并停在函数内的第一行代码。 - `print <variable>`:显示变量的当前值。 - `backtrace`:显示函数调用堆栈。 这些命令只是 GDB 的一部分,你还可以使用其他命令来满足你的调试需求。7. 在调试完成后,可以使用 `quit` 命令退出 GDB。希望这些步骤能够帮助你使用 GDB 调试你的程序。如有需要,...
