This is a case where the abstractions of the C programming language start to break down. 0 is indeed a null pointer constant in C, but the hardware sees 0 as a memory address like any other. Some systems have nothing valid there, but some other systems (like this one) put exception vectors at this location. When certain types of hardware interrupts or exceptions happen, the CPU jumps to certain fixed addresses around address 0 (the specific types of exceptions and the specific addresses are a property of the CPU architecture).

Platforms support. This code currently requires that you have a single NVIDIA GPU. In principle it is quite possible to support CPU, MPS and other platforms but this would also bloat the code. I'm not 100% sure that I want to take this on personally right now. The code is just a demonstration and I don't know how much I'll support it going forward. People can reference (or have their agents reference) the full/parent nanochat repository that has wider platform support and shows the various solutions (e.g. a Flash Attention 3 kernels fallback implementation, generic device support, autodetection, etc.), feel free to create forks or discussions for other platforms and I'm happy to link to them here in the README in some new notable forks section or etc.，更多细节参见PDF资料
Крупное красное пятно было заметно на правой стороне шеи полтика. Камеры большинства СМИ, как и официальные операторы Белого дома, стояли с противоположной стороны.
Both of these come with downsides. The former forces developers remember to perform certain checks before calling a method. The latter may require a whole bunch of dependencies to verify the parameters, in addition to the actual functionality the function is supposed to perform.，推荐阅读新收录的资料获取更多信息
