Cbc (Coin-orbranch andcut) is an open-source mixed integer linear programming solver written in C++. It can be used as a callable library or using a stand-alone executable. It can be used in a wide variety of ways through various modeling systems, packages, etc. ...
However, cudaMallocAsync has a minimum version requirement for cuda, which requires>=11.2. Please refer to:https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#id65 Thus, has Paddle discontinued support for compiling based on the develop branch with CUDA versions lower than 11.2?
