Hi to all!
I have just completed the installation of CUDA 11.3 on a fresh-installed Ubuntu 18.04 workstation.
I have followed all steps indicated in the Installation Guide Linux page, choosing the “deb (local)” method.
All installation steps has gone without any error, up to “9.2.3.3. Running the Binaries”, to verify the correct CUDA installation.
While the deviceQuery utility runs correctly, when I execute bandwidthTest I get a cudaErrorMemoryAllocation message, and I can’t figure out what’s wrong.
Some detail:

bandwidthTest output:
[CUDA Bandwidth Test] - Starting…
Running on…Device 0: NVIDIA Quadro 410
Quick ModeCUDA error at bandwidthTest.cu:715 code=2(cudaErrorMemoryAllocation) “cudaMalloc((void **)&d_idata, memSize)”
I also tried to compile and run the add.cu example code showed in the An Even Easier Introduction to CUDA page, it is compiled correctly, but when I run the add_cuda executable I get only a Segmentation fault error message.
How to get out of this issue?
Any indication to help me solve the problem will be greatly appreciated.
Please let me know if any further information is needed.
Thanks in advance!
