Description

The test_gpu.cpp example included in the testsuite builds with a non-gpu variant of hpx, but it fails with both rocm and cuda variants. There are cuda specific api calls in the code so I'm not surprised rocm fails (and I'm not sure how the non-cuda build is able to succeed). Could we get an updated test that can either handle both accelerator types, or get a working version for cuda and a new version for rocm? I didn't spot any existing test codes for hpx+gpus floating around in the hpx repo but if they exist I could import them to the testsuite myself.

This is observed with the current (24.05) e4s release which uses HPX@1.9.1. We should be at 1.10 for the next release so it's probably fine to target that if the implementations would be mutually exclusive.

Research direction

Start by reading test_gpu.cpp and compare the CUDA-specific calls with the HPX 1.9.1 ROCm build errors. Check the intended HPX 1.10 accelerator interfaces and build the executable with both CUDA and ROCm variants. Done means the test has a working implementation for both accelerator types, or clearly separated working variants.
