  In this updated vesion of ZMCintegral, we have added the functionality of
integrations with parameter scan on distributed Graphics Processing
Units(GPUs). Given a large parameter grid (up to 10^{10} parameter points to be
scanned), the code will evaluate integrations for each parameter grid value. To
ensure the evaluation speed, this new functionality employs a direct Monte
Carlo method for the integraion. The Python API is kept the same as the
previous ones and users have a full flexibility to define their own integrands.
The performance of this new functionality is tested for both one node and
multi-nodes conditions.
