They claim they are writing the actual kernel code (as in the implementation of a matmul) with it, and it was presented as a "system programming language": this goes far beyond "high-level tasks" it seems.

It depends what you mean by "new subsystem" and "transitioning to": what seems like a given is that the notion of "one size fits all" of LLVM IR is behind us and the need to multi-level IR is embraced. LLVM IR

TensorFlow is also a runtime, yet we model its dataflow graph (the input to the runtime) as a dialect, same for ONNX. TensorRT isn't that different actually.

All of Google TPU is powered by the XLA compiler, so any MLPerf benchmark result from Google comes powered by XLA. Anything JAX is also built on top of XLA, so you can take JAX performance as a point of comparison as well if you'd like

But these are options, it's not a big deal to me that compiler offers special options for special use cases. It's not clear to me if you are saying that the *default* for clang and GCC differs, aren't they both using `fno-wra

Can you elaborate on the signed integer overflow and the implicit initialization differences you're referring to?
12.
by Joky 5y ago
I don't think compiler implementations are responsible for the standard to refuse to endorse 2-complement (which is the root cause of signed overflow being UB originally if I understand correctly).

Python isn't really driving the compute intensive part of ML actually, whether it's JAX, PyTorch, or TensorFlow the code is really mostly native. Convolution are implemented by hand in highly optimized libraries (Intel MKL-DNN, Nv

I would double-check that it builds the exact same thing (there are lot of options when building LLVM, and CMake may auto-detect and enable support for things like Go bindings for example). Choice of compiler and compiler flags can make a d

You may not know, but: 1) LLVM does not use pull-request and code-review isn't mandatory for the main contributors. 2) until a few months ago LLVM didn't even have any testing system before the code is pushed to the master branch:
