How to change CUDA version
Perhaps cleaner: sudo update-alternatives –display cuda sudo update-alternatives –config cuda

Can I compile a cuda program without having a cuda device
The answer to your question is YES. The nvcc compiler driver is not related to the physical presence of a device, so you can compile CUDA codes even without a CUDA capable GPU. Be warned however that, as remarked by Robert Crovella, the CUDA driver library libcuda.so (cuda.lib for Windows) comes with the NVIDIA driver … Read more
Multiple CUDA versions on machine nvcc -V confusion
Solution as suggested in the comments: export PATH=/usr/local/cuda-8.0/bin:$PATH The problem was the ordering of $PATH, that my previous command had the =$PATH:/usr/local… instead of =/usr/local….:$PATH
What’s the relation between nvidia driver, cuda driver and cuda toolkit?
From cuda document http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#driver-api http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#versioning-and-compatibility It seems cuda driver is libcuda.so which is included in nvidia driver and used by cuda runtime api Nvidia driver includes driver kernel module and user libraries. Cuda toolkit is an SDK contains compiler, api, libs, docs, etc…
Are cuda kernel calls synchronous or asynchronous
Kernel calls are asynchronous from the point of view of the CPU so if you call 2 kernels in succession the second one will be called without waiting for the first one to finish. It only means that the control returns to the CPU immediately. On the GPU side, if you haven’t specified different streams … Read more
CUDA apps time out & fail after several seconds – how to work around this?
I’m not a CUDA expert, — I’ve been developing with the AMD Stream SDK, which AFAIK is roughly comparable. You can disable the Windows watchdog timer, but that is highly not recommended, for reasons that should be obvious. To disable it, you need to regedit HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Watchdog\Display\DisableBugCheck, create a REG_DWORD and set it to 1. You … Read more
Explanation of CUDA C and C++
CUDA C is a programming language with C syntax. Conceptually it is quite different from C. The problem it is trying to solve is coding multiple (similar) instruction streams for multiple processors. CUDA offers more than Single Instruction Multiple Data (SIMD) vector processing, but data streams >> instruction streams, or there is much less benefit. … Read more
What is the correct version of CUDA for my nvidia driver?
304.xx is a driver that will support CUDA 5 and previous (does not support newer CUDA versions.) If you want to reinstall ubuntu to create a clean setup, the linux getting started guide has all the instructions needed to set up CUDA if that is your intent. I believe you are picking up a 304.xx … Read more
