pub fn host(ordinal: usize) -> Result<Arc<CudaHost>>Expand description
Get (or create) the process CUDA host on ordinal.
The ordinal is fixed by the first call — a process serves one GPU, and a
later call asking for a different one is a bug worth reporting rather than
silently ignoring, which is exactly what the old get_or_init did with its
kernel_blobs argument.
