OpenCL

Detailed Description

Stan's OpenCL backend allows for computation to be executed in parallel on a GPU or in multithreaded CPUs.

It is meant to easily conform with Eigen such that you can create and read from a matrix_cl by doing

Eigen::MatrixXd A_eig = Eigen::MatrixXd::Random(10, 10);
matrix_cl<double> A(A_eig);
matrix_cl<double> B = to_matrix_cl(A_eig);
matrix_cl<double> C = cholesky_decompose(A * B);
// Read back to eigen matrix.
Eigen::MatrixXd C_eig = from_matrix_cl(C);
 
// Also for vectors and raw pointers of pointers
std::vector<var> A_vec(10, 0);
matrix_cl<var> B_var(A_vec, 10, 1);
 
vari** A_vari= // fill
matrix_cl<var> B_vari(A_vari, 10, 1);

Execution is performed in async and Kernel operations are compounded and compiled Just In Time. This allows for a low amount of overhead when passing data to and from the device and executing computations.
