[question] about DeviceRuntime::get_arch

[fishautumn]

why arch 10.x is specially converted to 100x instead of compile with original device arch?

    std::string get_arch(const bool& number_only = false,
                         const bool& support_arch_family = false) {
        const auto [major, minor] = get_arch_pair();
        if (major == 10 and minor != 1) {
            if (number_only)
                return "100";
            return support_arch_family ? "100f" : "100a";
        }
        return std::to_string(major * 10 + minor) + (number_only ? "" : "a");
    }
