Multi-threading and multi-process debugging: GDB supports debugging programs with multiple threads and processes, making it useful for complex applications. Memory debugging: Helps identify memory leaks and other memory-related issues by enabling detailed inspection of memory usage and allocations. To use...

前置:Linux多进程和多线程的一次gdb调试实例:https://typecodes.com/cseries/multilprocessthreadgdb.html ,Linux C/C++开发中gdb进行多进程和多线程的调试一直比较麻烦,在CSDN上看到高科的一篇文章《gdb调试多进程和多线程命令》比较有启发,这里就自己重新整理并做了一个GDB多进程/线程的调试实践。
3.3.7. Multiple Debuggers In a multi-GPU environment, several debugging sessions may take place simultaneously as long as the CUDA devices are used exclusively. For instance, one instance of CUDA- GDB can debug a first application that uses the first GPU while another instance of CUDA-GDB...
Debugging is a crucial aspect of software development. It’s the process of identifying and removing errors or ‘bugs’ in a software program. This process is not just about fixing errors; it’s also about understanding the program flow and ensuring it behaves as expected. ...
