The Ctrl-C signal will freeze the GPU and report back the source code location.

0123 Debug with cuda-gdb aout Usual gdb commands available NVIDIA Corporation 2009 52. This example shows how to enable CUDA-MEMCHECK from within CUDA-GDB and how to detect errors within the debugger so you can access the line number information and check the state of the variables In this example the unaligned kernel has a misaligned memory access in block 1 lane 1 which gets trapped as an illegal lane address at line 6 from. For larger applications in the case where you may just want to attach to a few of the processes you can conditionalize the spin loop based on the rank.
Single step executes only one warp except on sync threads. Using CUDA one can utilize the power of Nvidia GPUs to perform general computing tasks such as multiplying matrices and performing other linear algebra operations instead of just doing graphical calculations. The goal of its design is to present the user with an all-in-one debugging environment that is capable of debugging native host code as well as CUDA code.
You need to use a gpu-aware debugger such as cuda-gdb or NSight Visual Studio Edition or Eclipse Edition. CUDA 30 provides expanded capabilities. Sets Compiler ags Retains source code Disables compiler cache Andreas Kl ockner PyCUDA.

For the purpose of this tutorial we use a sample application called Matrix Multiply but you can follow the same procedures using your own source. CUDA CC Language Overview with simple examples The nvcc compiler Integration of CUDA code into existing projects Debugging return codes printf cuda-memcheck cuda-gdb Intermediate Example. The program below performs simple vector addition on the GPU and then prints the final contents of the result array c ie.
In the following tutorial we look at how to use some of the basic features of the CUDA Debugger. The debugger included with the CUDA toolkit is called cuda-gdb. Most MPIs set an environment variable that is the rank of the process.

CUDA-GDB provides support for debugging kernels that appear to be hanging or looping indefinitely. At this point the program can be modified and then resumed or terminated at the users discretion. For the purpose of this tutorial we use a sample application called Matrix Multiply but you can follow the same procedures using your own source.
