setup() [1/2]

void syten::Cuda::setup

(

)

Sets up CUDA to allow all existing devices and generates the associated cuBLAS handles for the calling thread.

Remarks

Subsequently-created OpenMP threads will have to create their own handles once required at some runtime cost. Take this into account when benchmarking. Unfortunately cuBLAS is (despite the documentation stating otherwise) not thread-safe.
