 The ELPA method need more parameter setting, but it doesn't seem to be affected by the CUDA toolkits version, and it is no need to manually install and package. 
 
+Note: ELPA-2025.01.001 may have problem in nvidia-GPU compilation on some V100-GPU with AMD-CPU machine, error message:

+And you may need to change ELPA version to 2024.05.001, edit `toolchain/scripts/stage3/install_elpa.sh` to do it.

 2. For the cusolvermp method, toolchain_*.sh does not need to be changed, just follow it directly install dependencies using `./toolchain_*.sh`, and then add
 ```shell
 -DUSE_CUDA=ON \
