Compiler and Debugger

The Compiler and Debugger allows you to deploy Kunpeng compilers in one click and debug GPU-based applications in a single-node system. It leverages CUDA-GDB debugging to debug GPU-based applications on a unified page. It also supports parallel debugging of applications on multiple nodes in HPC scenarios and remote compilation and debugging on the Kunpeng platform. It can debug code written in C, C++, or Fortran. The Compiler and Debugger performs the following functions:

One-click deployment of Kunpeng compilers (GCC for openEuler, BiSheng Compiler, and BiSheng JDK)
Visualized configuration of compilation and debugging parameters and one-click code compilation, execution, and debugging
Remote, single-step debugging of C/C++ code
Real-time interaction of the compilation and debugging information
Source and assembly code debugging of CUDA applications
Source and assembly code debugging of HPC applications, display of historical communication group details, and stack switchover

General Application Debugging

General application debugging offers remote debugging capabilities on the Kunpeng platform, featuring a graphical user interface (GUI) that significantly improves debugging efficiency.

Set parameters of general application debugging. See Figure 2.
Figure 2 Parameters of general application debugging
Debug a general application. See Figure 3. You can set breakpoints, perform single-step debugging, and view variables and registers.

Parallel HPC Application Debugging

The Compiler and Debugger supports parallel debugging on multiple nodes in HPC scenarios. MPI applications can only be debugged in launch mode.

Set parameters of parallel HPC application debugging. See Figure 4.
