BdaBridge acts as interface between opm-simulators with the BdaSolvers.
◆ BdaBridge()
Construct a BdaBridge.
- Parameters
-
[in] | accelerator_mode | to select if an accelerated solver is used, is passed via command-line: '–accelerator-mode=[none|cusparse|opencl|amgcl|rocalution|rocsparse]' |
[in] | linear_solver_verbosity | verbosity of BdaSolver |
[in] | maxit | maximum number of iterations for BdaSolver |
[in] | tolerance | required relative tolerance for BdaSolver |
[in] | platformID | the OpenCL platform ID to be used |
[in] | deviceID | the device ID to be used by the cusparse- and openclSolvers, too high values could cause runtime errors |
[in] | opencl_ilu_parallel | whether to parallelize the ILU decomposition and application in OpenCL with level_scheduling |
[in] | linsolver | indicating the preconditioner, equal to the –linear-solver cmdline argument |
◆ copySparsityPatternFromISTL()
Store sparsity pattern into vectors.
- Parameters
-
[in] | mat | input matrix, probably BCRSMatrix |
[out] | h_rows | rowpointers |
[out] | h_cols | columnindices |
◆ get_result()
Get the resulting x vector.
- Parameters
-
[in,out] | x | vector x, should be of type Dune::BlockVector |
◆ initWellContributions()
Initialize the WellContributions object with opencl context and queue those must be set before calling BlackOilWellModel::getWellContributions() in ISTL.
- Parameters
-
[in] | wellContribs | container to hold all WellContributions |
[in] | N | number of rows in scalar vector that wellContribs will be applied on |
◆ solve_system()
Solve linear system, A*x = b.
- Warning
- Values of A might get overwritten!
- Parameters
-
[in] | bridgeMat | matrix A, should be of type Dune::BCRSMatrix |
[in] | jacMat | matrix A, but modified for the preconditioner, should be of type Dune::BCRSMatrix |
[in] | numJacobiBlocks | number of jacobi blocks in jacMat |
[in] | b | vector b, should be of type Dune::BlockVector |
[in] | wellContribs | contains all WellContributions, to apply them separately, instead of adding them to matrix A |
[in,out] | result | summary of solver result |
