possible memory leak in Kokkos::initialize() cuda implementation

12

**Describe the bug** I'm developing and testing a new feature in APEX to report memory leaks on the GPU (cuda, hip, etc.). When I tested with a Kokkos application, it...

Allow HPX counters to be requested before they are registered

## Expected Behavior The current HPX counter interface expects that all counters are registered during HPX initialization. However, in order for APEX to share counters with HPX, APEX won't register...
