pub const cudaErrorDevicesUnavailable: cudaError = 46;Expand description
This indicates that all CUDA devices are busy or unavailable at the current time. Devices are often busy/unavailable due to use of ::cudaComputeModeProhibited, ::cudaComputeModeExclusiveProcess, or when long running CUDA kernels have filled up the GPU and are blocking new work from starting. They can also be unavailable due to memory constraints on a device that already has active CUDA work being performed.
