NSIGHT Debug CUDA grid launch failed

Hello every one,

I have installed CUDA and started working with it (successfully launched several .cu files, tested nvcc and nvprof).

I am now at the step where I would like to debug my work in CUDA (access to kernels).

I have tried several attempts, but with always the same output:CUDA grid launch failed.

Let me detail this on one example, the MatrixMul CUDA sample, which is detailed in the Nsight VIsual Studio User Guide :

My system (as detailed in the Nsight ->Windows->System Info) is:

Name Intel(R) Core™ i7-4700MQ CPU @ 2.40GHz
Architecture x64
Frequency 2 394 MHz
Number of Cores 8
Page Size 4 096
Total Physical Memory 7 993.00 MB
Available Physical Memory 2 091.00 MB

deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 10.1, CUDA Runtime Version = 10.1, NumDevs = 1
Result = PASS

I have followed all the instructions on the Nsight User Guide in the CUDA Debugger Walkthrough : Debugging a CUDA application, and when I launch the Nvidia CUDA Debugger (Legacy) the Nsight Output is:

CUDA context created : 1e9fa5a26e0
CUDA module loaded: 1e9fd0c20d0 matrixMul.cu
CUDA grid launch failed: CUcontext: 2104439219936 CUmodule: 2104484438224 Function: _Z13MatrixMulCUDAILi32EEvPfS0_S0_ii

I have tried to increase the TDR Delay to 10 in the Nsight monitor option, without any success. I give you below my setting:

I am stuck on this, and any help or suggestion would be greatly appreciated.
