Contribution
The paper presents a new version of ZMCintegral supporting simultaneous multi-function integrations on GPUs, maintaining a user-friendly Python API.
Findings
Supports over 1000 functions on GPUs
Evaluation time less than 10 minutes for 1000 integrals in <5D
Performance scales linearly with GPU count
Abstract
In this new version of ZMCintegral, we have added the functionality of multi-function integrations, i.e. the ability to integrate more than different functions on GPUs. The Python API remains the similar as the previous versions. For integrands less than 5 dimensions, it usually takes less than 10 minutes to finish the evaluation of integrations on one Tesla v100 card. The performance scales linearly with the increasing of the GPUs.
