問題文
A data center team has just racked its first accelerated servers. The application developers report that their framework code cannot see any accelerator at all, even though the hardware is installed and powered. The team needs to understand which layer of the software stack has to be in place before anything above it can work. Which layer is that?
選択肢
- The kernel-mode driver, because every higher layer reaches the hardware through it.
- The container runtime, because accelerators are only visible to processes that run inside a container image.
- The numerical libraries, which enumerate the devices and hand the list to the framework above them.
- The inference serving layer, which registers the devices at start-up and hands them upward.
