Well, we're building - they're paying :). I tweeted some photos here for people who want to see our initial testbed (yes, this is completely off the shelf hardware - part of the point of the project is to see how far we can take that): https://twitter.com/KenoFischer/status/1412517017354178561. Happy to answer questions if people have them :).

Edit: The original title of this was "Julia Computing and DARPA to build ...", which is what this comment is referring to ;). Thanks for updating the title.

Since it’s not exactly clear to me… what’s the idea behind the project? Is it just being able to compile generic (linear algebra like) beam forming code for XLA/GPU backed a with self-tuning parameters? Is is more than that?

That (but with Julia rather than XLA obviously) coupled to high performance data paths between the GPU and SDR.
