llvm dev - May 2018 - Thank you from the Glow Developers

Hello LLVM community,

We have been working hard on a new domain specific optimizing compiler, and
we
are pleased to announce that we have recently open sourced the project!  We
would like to introduce you to Glow, an optimizing compiler for neural
networks!

This new compiler is built on the hard work of this community and we would
like
to thank all of the contributors to the LLVM project.  We hope that the
project
will be beneficial to others as well, which would not have been possible
without
your work.

You can find the sources to it at http://github.com/pytorch/glow and read
up on
the work in the associated paper we have released at
https://arxiv.org/pdf/1805.00907.

Thank you all!

The Glow Developers

Very cool! The first thing that jumps out to me is how tidy and modular the
code structure is. The code feels very familiar (stylistically,
organizationally, etc.) to me as an LLVM developer.

One thing that wasn't at all clear to me is how this is different/similar
to TensorFlow XLA (previously mentioned on this list). Can you briefly
compare and contrast this with TensorFlow XLA?

Hi Sean,

Sorry for the delay.

Thanks!  We absolutely took inspiration from the wonderful work in LLVM :).
I’m glad that you found it familiar and tidy.

That is a very keen observation.  There are many similarities between the
two projects.  However, there are some differences too.

Both are interested in performing cross-node optimizations to address
memory usage and execution time.  In order to accomplish their goals, both
have their own IR and optimization passes.

At the same time, there seem to be some differences as well.  In the case
of glow we have focused on the use of Caffe2 models and have support for
the ONNX format as well.  We have been trying to focus on providing a more
target independent model and have been considering some heterogeneous
execution models as well.  XLA is definitely a more mature compiler
compared to glow.

I think that there are sufficient similarities and differences that there
are ample opportunities for collaboration as these projects grow further.
