scoped_range does not work with domain::global

[zygfrydw]

I am trying to use NVTX3_FUNC_RANGE(), nvtx3::scoped_range or nvtx3::scoped_range_in<nvtx3::domain::global> but neither is working - the range does not show in nvperf / nvvp.

I have tested nvtxRangePush and nvtx3::scoped_range_in<my_domain> and these ranges show in profiling tools correctly.

Configuration

• GPU CARD: GeForce GTX 1650 Mobile
• driver version: 520.61.05
• CUDA version: 11.8
• OS version: Ubuntu 22.04

Reproduction docker

I have prepared a simple reproduction docker here.

Reproduction code:

struct my_domain{ static constexpr char const* name{"my_domain"}; };

void function_my_domain(){
    // this range does show in profiling tools as expected
    nvtx3::scoped_range_in<my_domain> r(__FUNCTION__);
    std::this_thread::sleep_for(1s);
}

void function_global(){
    // this range does not show in profiling tools
    nvtx3::scoped_range r(__FUNCTION__);
    std::this_thread::sleep_for(1s);
}

I have done some experiments with NVTX source code and the following changes seams to fix the issue:

I have changed

// NVTX/include/nvtx3/nvtx3.hpp line 940
template <>
inline domain const& domain::get<domain::global>() noexcept
{
  static domain const d{};
  return d;
}

to:

template <>
inline domain const& domain::get<domain::global>() noexcept
{
  static domain const d{"global"};
  return d;
}

Can you verify if the modification makes sense to other NVIDIA tools?
