Initialization and configuration

HYPRE.Init — Function
Init(; finalize_atexit=true)

Wrapper around HYPRE_Init. If finalize_atexit is true a Julia exit hook is added, which calls HYPRE_Finalize. This method will also call MPI.Init unless MPI is already initialized.

Note: This function must be called before using HYPRE functions.

-HYPRE.start_assemble!(A::HYPREMatrix, b::HYPREVector) -> HYPREAssembler
Initialize a new assembly for matrix A, vector b, or for both. This zeroes out any previous data in the arrays. Return a HYPREAssembler with allocated data buffers needed to perform the assembly efficiently.

 HYPRE.assemble!(A::HYPREAssembler,       ij,   a::Matrix, b::Vector)
Assemble (by adding) matrix contribution a, vector contribution b, into the underlying array(s) of the assembler at global row indices i and column indices j.
This is roughly equivalent to:
# A.A::HYPREMatrix
 A.A[i, j] += a
 
 # A.b::HYPREVector
-A.b[i] += b

solve!(solver::HYPRESolver, x::HYPREVector, A::HYPREMatrix, b::HYPREVector)
Solve the linear system A x = b using solver with x as the initial guess. The approximate solution is stored in x.

solve(solver::HYPRESolver, A::HYPREMatrix, b::HYPREVector) -> HYPREVector
Solve the linear system A x = b using solver and return the approximate solution.
This method allocates an initial guess/output vector x, initialized to 0.

HYPRE.jl

HYPRE.jl is a Julia wrapper for the HYPRE library, which provide parallel solvers for sparse linear systems.

High level interface

HYPRE.jl provide a high level interface to the HYPRE library. The goal of this interface is that the style and API should feel natural to most Julia programmers (it is "Julian"). In particular, you can use standard sparse matrices together with HYPRE's solvers through this interface.

The high level interface does not (currently) provide access to all of HYPREs functionality, but it can easily be combined with the low level interface when necessary.

Low level interface

HYPRE.jl also provide a low level interface for interacting with HYPRE. The goal of this interface is to stay close to the HYPRE C API. In fact, this interface is automatically generated based on HYPRE's header files, so this API maps one-to-one with the C API, see LibHYPRE C API for more details.

LibHYPRE C API

The submodule HYPRE.LibHYPRE contains auto-generated bindings to the HYPRE library and give access to the HYPRE C API directly[1]. The module exports all HYPRE_* symbols. Function names and arguments are identical to the C-library – refer to the HYPRE manual for details.

The example program examples/ex5.jl is an (almost) line-to-line translation of the corresponding example program examples/ex5.c written in C, and showcases how HYPRE.jl can be used to interact with the HYPRE library directly.

Functions from the LibHYPRE submodule can be used together with the high level interface. This is useful when you need some functionality from the library which isn't exposed in the high level interface. Many functions require passing a reference to a matrix/vector or a solver. HYPRE.jl defines the appropriate conversion methods used by ccall such that

  • A::HYPREMatrix can be passed to HYPRE_* functions with HYPRE_IJMatrix or HYPRE_ParCSRMatrix in the signature
  • b::HYPREVector can be passed to HYPRE_* functions with HYPRE_IJVector or HYPRE_ParVector in the signature
  • s::HYPRESolver can be passed to HYPRE_* functions with HYPRE_Solver in the signature
