Could you build this?
No Designing a compiler and kernel language that lowers to PTX for NVIDIA GPUs and manages tile DAGs requires deep domain expertise in compiler construction, MLIR/LLVM, and GPU hardware architectures.
What it would actually take: The architecture entails an MLIR-based compiler pipeline targeting NVIDIA PTX, featuring custom memory tile scheduling, distributed DAG orchestration, and hardware-specific shared memory/register optimizations. Building this requires specialized expertise in low-level GPU programming (CUDA, PTX), compiler internals (MLIR, LLVM), and high-performance numerical computing.
Discussion
2 comments analyzed.
Concerns raised: Unvalidated at scale - only single-GPU numbers tested, Unclear how thousands of GPUs are actually coordinated and controlled, Scalability architecture not proven in practice
