Those long lines could use some wrapping. It may be a good idea to just clang-format the sources.

Nit: I'd just use some kind of map here. Else/ifs with explicit conversion to string just clutter things up. Not that it matters much here, but...
std::string demangle(const char *name) {
static std::pair<std::string, std::string> map[] = {{"f", "float"}, {"i", "int"}};
for (auto p : map) {
if (p.first == name)
return p.second;
}
return name;
}

I do not know what would be the correct answer here, unless the user explicitly tells me that they do want to compare a negative signed value as an unsigned one.

this assumes CUDA compatibility, which assumes the result of x<y?x:y with the implicit signed-to-unsigned conversion is correct. I can put a comment for clarification.
