MatCreateDenseHIP#

Creates a matrix in MATDENSEHIP format using HIP.

Synopsis#

PetscErrorCode MatCreateDenseHIP(MPI_Comm comm, PetscInt m, PetscInt n, PetscInt M, PetscInt N, PetscScalar *data, Mat *A)

Collective

Input Parameters#

  • comm - MPI communicator

  • m - number of local rows (or PETSC_DECIDE to have calculated if M is given)

  • n - number of local columns (or PETSC_DECIDE to have calculated if N is given)

  • M - number of global rows (or PETSC_DECIDE to have calculated if m is given)

  • N - number of global columns (or PETSC_DECIDE to have calculated if n is given)

  • data - optional location of GPU matrix data. PassNULL to have PETSc to control matrix memory allocation.
