multi-core/GPU acceleration support in atchem2

[harryPKU]

Dear atchem2 developers,

First, thank you for your work on this valuable atmospheric chemistry model. I would like to inquire about its computational performance capabilities.

Specifically:

1. Multi-core support:Does atchem2 have built-in parallelization to utilize multiple CPU cores?
2. GPU acceleration:Is there support for GPU-accelerated computations (e.g., via CUDA or OpenCL)?

If these features are available:

• Could you provide guidance on how to enable them？
• Are there example configurations demonstrating optimal usage?

If not currently supported:

• Are there plans to implement such optimizations in future releases?

Thank you for your time and expertise.

Hi @harryPKU at the momen, parallelization is not implemented. I can see the potential benefits, and it may be implemented in the future, but I cannot give a timeline for this because my resources are currently limited.
If somebody is willing to help with the implementation I am happy to support it, of course :)
