Out Of Memory error with HIP

[gzagaris]

When using camp with RAJA, I am getting the following out-of-memory error from camp:

terminate called after throwing an instance of 'std::runtime_error'
  what():  campHipErrchk(hipStreamCreate(&s)) out of memory .../camp/include/camp/resource/hip.hpp:154

The relevant code is the following:

     static Hip get_default()
      {
        static Hip h([] {
          hipStream_t s;
#if CAMP_USE_PLATFORM_DEFAULT_STREAM
          s = 0;
#else
          campHipErrchk(hipStreamCreate(&s));
#endif
          return s;
        }());
        return h;
      }

• Is camp inadvertently creating streams and never deleting them?
• If I pass the -DCAMP_USE_PLATFORM_DEFAULT_STREAM=1, I get passed this error (and kick the pesky core dump a bit further down). Is passing -DCAMP_USE_PLATFORM_DEFAULT_STREAM=1 what the recommendation is for AMD GPUs?

Thank you for all your help.
