choosing GPU_DEVICE from gpu.config doesn't work about npb-gpu HOT 2 OPEN

Hello, @odiakun.

First of all, thank you for using the NPB-GPU.

Second, are you recompiling the benchmark after modifying the gpu.config file? After making changes to the gpu.config file, it's essential to recompile the benchmark for the modifications to be applied and take effect.

Third, have you downloaded the latest version of NPB-GPU? We updated NPB-GPU a few days ago to automatically collect the compute capability according to the GPU_DEVICE in the gpu.config file.

In the latest version of NPB-GPU, when you compile a benchmark, the terminal will show a message if a GPU device is not valid. For example:

The GPU id 5 is not valid. Using GPU 0 as default.
Updated COMPUTE_CAPABILITY (GPU of id 0) in ../config/make.def to -gencode arch=compute_89,code=sm_89

I have a few questions for you:

1. Is the GPU device being correctly selected in the other benchmarks CG, EP, FT, IS, and MG?
2. When we compile a benchmark, it generates a file named npbparams.hpp in the directory of the benchmark you are compiling. Can you share the npbparams.hpp file generated?
3. Can you share the output of the compilation and execution?
4. What are your GPUs and CUDA versions?
5. If the GPU_DEVICE occurs several times in the gpu.config file, NPB-GPU collects only the first occurrence. You provided the GPU device info in the first lines of the gpu.config file, right?

from npb-gpu.

Could you modify the gpu.config file and recompile the benchmark?
