Now it is demonstrated how we can compute this efficiently, even when it requires the user to write a routine for this. The (slow) but automatic method is also available (useful in case you solve new equations) --- examples/DMSTAG_porwave_2D.jl | 140 +++++++++++++++++++++++++++------- 1 file changed, 114 insertions(+), 26 deletions(-) diff --git a/examples/DMSTAG_porwave_2D.jl b/examples/DMSTAG_porwave_2D.jl index d2e8561a..6fec91d3 100644 --- a/examples/DMSTAG_porwave_2D.jl +++ b/examples/DMSTAG_porwave_2D.jl @@ -74,37 +74,34 @@ function FormJacobian!(cx_g, J, P, user_ctx) PETSc.DMGlobalToLocal(user_ctx.dm, cx_g, PETSc.INSERT_VALUES, user_ctx.x_l) x = PETSc.unsafe_localarray(Float64, user_ctx.x_l.ptr; write=false, read=true) - if isnothing(user_ctx.jac) - # Compute sparsity pattern of jacobian.

In a default build of the package, all types can be used -simultaneously, using multiple dispatch to determine which version of PETSc -to use. +This package provides a low level interface for [PETSc](https://www.mcs.anl.gov/petsc/) and allows combining julia features (such as automatic differentiation) with the PETSc infrastructure and nonlinear solvers. -This package requires the [MPI.jl package](https://github.com/JuliaParallel/MPI.jl) be installed. Once it is installed you should be able to run both Julia and Petsc in parallel using MPI for all communication. The testing verifies that PETSc can be used both serially and in parallel. - -To use the package, simply put `using PETSc` at the top of your Julia source file. The module exports the names of all the functions, as well as the PETSc data type aliases and constants such as `PETSC_DECIDE`. - -In general, it is possible to run PETSc in parallel. To do so with 4 processors, do: +## Installation +This package can be added with the julia command: +```julia +]add https://github.com/JuliaParallel/PETSc.jl ``` -mpirun -np 4 julia ./name_of_file +The installation can be tested with +```julia +]test PETSc ``` -Note that this launches 4 independent Julia processes. They are not aware of each other using Julia's built-in parallelism, and MPI is used for all communications. - -To run in serial, do: -``` -julia ./name_of_file -``` - -Even when running serially, the [MPI.jl package](https://github.com/JuliaParallel/MPI.jl) must be installed. - - -An example of using a Krylov subspace method to solve a linear system is in `test/test_ksp.jl`, which solves a simple system with a Krylov subspace method and compares the result with a direct solve using Julia's backslash operator. This works in serial and in parallel. It requires some variables declared at the top of `runtests.jl` to work. - - - -## To do: - * Make the script for building PETSc more flexible, e.g. allowing more configuration options like building BLAS or LAPCK, while ensure it remains completely autonomous (needed for Travis testing) - * Wrap more KSP functions - -## Status -### Vector - The `AbstractArray` for `PetscVec` is implemented. Some additional PETSc - BLAS functions are wrapped as well. -### Matrix - The AbstractArray interface for `PetscMat` is implemented. Preallocation - is supported through optional keyword arguments to the matrix constructor or - the `setpreallocation` function. It possible to set multiple values in the - matrix without intermediate assembly using the `assemble` function or by - setting the `Mat` object field `assembling` to `false` and calling `setindex` - repeatedly. - -### KSP - Just enough KSP functions are implimented to do a GMRES solve. Adding more -functionality is the current priority. - -## Directory Structure - `/src` : source files. PETSc.jl is the main file containing initialization, with the functions for each type of Petsc object in its own file. All constants are declared in `petsc_constants.jl`. - - `/src/generated`: auto generated wrappers from Clang.jl. Not directly useful, but easy to modify to make useful - - `/test` : contains `runtest.jl`, which does some setup and runs all tests on all three version of Petsc currently supported. Tests for each type of Petsc object (mirroring the files in `/src`) are contained in separate files. - - `/deps` : builds Petsc if needed. See description below - - -## Building PETSc -By default, building the package will build 3 versions of PETSc in the `/deps` - directory, and writes the file `lib_locations.jl` to the `/deps` - directory to tell the package the location of the libraries. Note that -this builds the debug versions of PETSc, which are recommended to use for all -development. If you wish to do high performance computations, you should -build the optimized versions of the library. See the PETSc website for -details. - -If you wish to build fewer than 3 version of PETSc or to use your own build -of PETSc rather than having the package build it for you, there a several -environmental variables that control what the build system will do. -For all the variables listed below, `name` is one of `RealDouble`, `RealSingle`, -or `ComplexDouble`, and specifies which version of the library the variable -describes. - -### What to build -If the varibles `JULIA_PETSC_name_DIR` and `JULIA_PETSC_name_ARCH` are set to -the `PETSC_DIR` and `PETSC_ARCH` of an existing PETSc installation, the build -system will use that PETSc installation for the version of PETSc specified by -`name`. - -If the variable `JULIA_PETSC_name_NOBUILD` exists (the value does not matter), -then the package will not build a version the `name`d version of PETSc. - -### How to build it -If the variable `JULIA_PETSC_OPT` exists (the value does not matter), then -a set of default optimization flags are passed to the PETSc `configure` -script. - -If the variable `JULIA_PETSC_FLAGS` exists and `JULIA_PETSC_OPT` does not, -its value is used passed to the -PETSc configure script (for all builds). The user should *never* specify `--with-64-bit-indices`, `--with-scalar-type` or `--with-precision`, because this -would break the build process for the different version of PETSc. - -If neither of the above variables exist, a standard build is performed. - +## Caveats -## Auto Generation Notes -PETSc uses preprocessor variables to decide what code to include when compiling -the library. Clang does not know what preprocessor variables were defined at -compile time, so it does not correctly detect the typealiases `PetscScalar`, `PetscReal`, etc. To correctly autogenerate wrappers, the proper variables must be passed to Clang with the -D switch. Note that users will not need to generate their own wrappers because they have already been generated and commit to the repo. +The package uses a pre-build binary of [`PETSc`](https://github.com/JuliaBinaryWrappers/PETSc_jll.jl) that is automatically installed, along with a default installation of `MPI.jl`; use of system install MPI and PETSc is not currently supported. Also note that `PETSc_jll.jl` is currently not working on Windows for julia > 1.3. diff --git a/examples/DMSTAG_Stokes_2D.jl b/examples/DMSTAG_Stokes_2D.jl index 4e482803..20d04bfa 100644 --- a/examples/DMSTAG_Stokes_2D.jl +++ b/examples/DMSTAG_Stokes_2D.jl @@ -14,16 +14,13 @@ # | Tzz | = | 0 2*eta 0 | | Ezz | | Linear viscous (isotropic) rheology # | Txz | | 0 0 eta | | Exz | # -# This exemple also uses the Automatic differenciation package ForwardDiff +# This example also uses the Automatic differentiation package ForwardDiff using PETSc, MPI -using Plots using ForwardDiff, SparseArrays, SparseDiffTools PETSc.initialize() - - function FormRes!(f_g, x_g, user_ctx) # Copy global to local vectors @@ -125,12 +122,11 @@ function FormJacobian!(cx_g, J, P, user_ctx) user_ctx.jac = jac; user_ctx.colors = colors; - return jac, ind end # Define a struct that holds data we need in the local SNES routines below -mutable struct Data +mutable struct Data_Stokes2D # DMs and vectors dm dmCoeff @@ -154,7 +150,7 @@ mutable struct Data jac_cache colors end -user_ctx = Data(nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing); # holds data we need in the local +user_ctx = Data_Stokes2D(nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing, nothing); # holds data we need in the local function ComputeLocalResidual(dm, ArrayLocal_x, ArrayLocal_f, user_ctx) @@ -446,9 +442,20 @@ xc_1D = XCoord_c[:,1]; zc_1D = ZCoord_c[1,:]; # Plot -p1 = heatmap(xe_1D,ze_1D, P', xlabel="Width", ylabel="Depth", title="Pressure",aspect_ratio = 1) -p2 = heatmap(xe_1D,zc_1D, Vz', xlabel="Width", ylabel="Depth", title="Vz",aspect_ratio = 1) -p3 = heatmap(xc_1D,ze_1D, Vx', xlabel="Width", ylabel="Depth", title="Vx",aspect_ratio = 1) -#quiver!(XCoord_e[:],ZCoord_e[:],quiver=(Vx_cen[:]*0.02,Vz_cen[:]*0.02), color=:white,aspect_ratio = 1) -p4 = heatmap(xe_1D,ze_1D, Eta', xlabel="Width", ylabel="Depth", title="Eta",aspect_ratio = 1) -plot(p1, p2, p3, p4, layout = (2, 2), legend = false) \ No newline at end of file +CreatePlots = false; # set to false by default such that testing does not require Plots +if CreatePlots + using Plots + + p1 = heatmap(xe_1D,ze_1D, P', xlabel="Width", ylabel="Depth", title="Pressure",aspect_ratio = 1) + p2 = heatmap(xe_1D,zc_1D, Vz', xlabel="Width", ylabel="Depth", title="Vz",aspect_ratio = 1) + p3 = heatmap(xc_1D,ze_1D, Vx', xlabel="Width", ylabel="Depth", title="Vx",aspect_ratio = 1) + #quiver!(XCoord_e[:],ZCoord_e[:],quiver=(Vx_cen[:]*0.02,Vz_cen[:]*0.02), color=:white,aspect_ratio = 1) + p4 = heatmap(xe_1D,ze_1D, Eta', xlabel="Width", ylabel="Depth", title="Eta",aspect_ratio = 1) + plot(p1, p2, p3, p4, layout = (2, 2), legend = false) + +end + +# check if the solution makes sense +using LinearAlgebra, Test +check = norm(user_ctx.x_l) +@test check ≈ 31.54688642064483 \ No newline at end of file diff --git a/examples/DMSTAG_porwave_1D.jl b/examples/DMSTAG_porwave_1D.jl index 02adc13d..4f297998 100644 --- a/examples/DMSTAG_porwave_1D.jl +++ b/examples/DMSTAG_porwave_1D.jl @@ -1,6 +1,7 @@ # This is an example of a 1D viscoelastic porosity wave as described in # Vasyliev et al.

I'm not sure it makes sense to do that @ this time as @jkozdon has done much of that already in the branch that generates Clang bindings. Therefore I have deactivated testing of most of the DMSTAG examples for now. --- examples/DMSTAG_Stokes_2D.jl | 4 + examples/DMSTAG_porwave_1D.jl | 11 +- examples/DMSTAG_porwave_2D.jl | 3 + examples/Diffusion_2d.jl | 3 + examples/ex1.jl | 5 + src/dmstag.jl | 53 ++++---- test/dmda.jl | 2 +- test/test_dmstag.jl | 237 +++++++++++++++++----------------- 8 files changed, 173 insertions(+), 145 deletions(-) diff --git a/examples/DMSTAG_Stokes_2D.jl b/examples/DMSTAG_Stokes_2D.jl index 7149753d..6c787d15 100644 --- a/examples/DMSTAG_Stokes_2D.jl +++ b/examples/DMSTAG_Stokes_2D.jl @@ -1,3 +1,7 @@ +# EXCLUDE FROM TESTING +# NOTE: This is temporarily not working until we merge the DMSTAG routines with the new Clang branch +# +# # This shows how to solve the 2D incompressible Stokes equations using SNES solvers, # using a staggered grid discretization and a Velocity-Pressure formulation # diff --git a/examples/DMSTAG_porwave_1D.jl b/examples/DMSTAG_porwave_1D.jl index 3bf3e61b..518f8c4e 100644 --- a/examples/DMSTAG_porwave_1D.jl +++ b/examples/DMSTAG_porwave_1D.jl @@ -1,3 +1,7 @@ +# EXCLUDE FROM TESTING +# NOTE: This is temporarily not working until we merge the DMSTAG routines with the new Clang branch +# +# # This is an example of a 1D viscoelastic porosity wave as described in # Vasyliev et al.
