Opm::WellContributionsCuda::setCudaStream
void setCudaStream(cudaStream_t stream)
Set a cudaStream to be used.
Opm::WellContributionsCuda::apply
void apply(Scalar *d_x, Scalar *d_y)
Apply all Wells in this object performs y -= (C^T * (D^-1 * (B*x))) for all Wells.
Opm::WellContributionsCuda::APIalloc
void APIalloc() override
Allocate memory for the StandardWells.
Opm::WellContributionsCuda::APIaddMatrix
void APIaddMatrix(MatrixType type, int *colIndices, Scalar *values, unsigned int val_size) override
Store a matrix in this object, in blocked csr format, can only be called after alloc() is called.
