A comment on Huawei Seeks Independence from the US with RISC-V and Ascend Chips. Parent comment
- GPUs don't handle I/O other than writing to video RAM.
- GPUs don't handle interrupts.
- GPUs don't handle branching well.
For the first two, a lot of infrastructure that is part of the chipset and platform would have to be extended to each compute unit of the GPU.
Imagine a database on a GPU. It's not like 1.5K-2k+ cores that are super good at math can read and write your disk or disk array at once.
