Description

Sundials has a few "massively parallel" solvers that can solve many independent models in parallel on a GPU (SUNLinSol_OneMklDense and SUNLinSol_MagmaDense for dense systesm, SUNLinSol_cuSolverSp_batchQR for sparse). These could be used for parameter sweeps, data generation or inference.

See also #2217

Motivation

enable the use of GPUs to solver a large number of PyBaMM models in parallel

Possible Implementation
