In the implementation, the most computationally intensive processes\u2014the calculation of the pair energies and the construction of the correlation function\u2014have been optimized for GPUs. ERmod\u2010OpenACC also supports single precision to maximize performance on RTX series GPUs, which are commonly used in molecular dynamics simulations. A common problem with OpenACC is data transfer between the CPU and GPU. By minimizing data transfer, the package's performance has been significantly improved. Compared to a single Xeon core (3.1 GHz), ERmod\u2010OpenACC achieves a speedup of up to approximately  when running on RTX 4080 SUPER. The package also supports multiple GPUs via MPI, achieving a speedup of  with 2 GPUs and approximately  with 16 GPUs. The only external library required to compile ERmod\u2010ACC is NVIDIA HPC SDK.
