I have a few questions.

How do I view html outputs. I ran the 'sierpinski' example but I just got a reproduction of the source code and "html output" at the end.
Most of the examples I run just reproduce the code. Is this deliberate? How do I see results or better still, what am I misunderstanding about the whole process.
How do I select between the cuda backend and cpu and is there a multithreaded backend?

You can use dex web to open up the script in our notebook interface and dex script --outfmt html to convert a script into an HTML file that embeds the outputs. If you run dex script then any :html pragma will print <html output> since it can't be displayed in a terminal.
Yes, dex script reproduces the whole script and prints the result of evaluating every top-level expression right after it. You can use dex script --outfmt result-only to change this behavior.
All commands accept a --backend flag. llvm-cuda is the GPU backend while llvm-mc is the multicore CPU backend. But both can be flaky at times because we don't have full CI for them. Please open an issue if they don't work for you.

Thank you.
(1) and (2) work fine but not the GPU or multicore backend. I will open an issue now.
