That is correct (and we appreciate the citation). The tensor compiler (taco) has focused on compiling expressions that contain one or more sparse tensors so far and, even though it…

The story for sparse matrices is more complicated. Because of the dependencies imposes by sparse data structures (you don’t have random access and often have to traverse them) you …

We’ve tried to engineer it to emit clean code, but seems we left in some unused variables. The C compilers dead code elimination should remove those though.

We currently compile to C code and use the system Compiler to compile it further. For dense loop nests it does a good job of auto-vectorizing, but we believe there’s good opportuni…

That is a good idea, but we are only so many. One student in the Julia group is developing Julia bindings though, and we hope to make C/python bindings. The inner workings are publ…

Thanks, that is really nice of you :)

For sure, as you point out, many such kernels have been written, going at least as far back as 1967. We believe our contribution is being able to generate kernels for all the expre…

I don't know of an explicit list like this, but some areas that we are particularly interested in are: data analytics (tensor factorization), machine learning (anything sparse incl…

Thanks! I really like that conference!

Hi, that sounds very interesting and I hope someone works on it. We're only so many people though, and we have several things we want to do that will at least occupy us until next …

Larry chose to focus on the big data part, because it is intuitive. But I think you're absolutely correct, that it has applications in physics/chemistry (and machine learning too).…

Hi Hacker News! I’m one of the developers. This project was also featured in MIT News yesterday: http://news.mit.edu/2017/faster-big-data-analysis-tensor-alg... The code is availab…

Thanks! Yes, we have an `apps` directory in the source tree that we will add programs to. These programs are tested by our test suites, and will later be our performance regression…

Very valid concerns. If you use C++ it's easy to interoperate with Simit, since Simit is a C++ library with an online compiler that compile the time steppers. You build the graph u…

We needed new language constructs (the matrix assembly) and a new type system for matrices that ties back to the graph to make it simple and fast. It is also not limited to FEM cod…

It actually shares two authors (Jon and Saman). Their work on Halide was amazing!
