This is a workaround for a well known. # limitation of Docker that you cannot cleanup after an ADD operation. # This reduces the container size by around 80MB as the /src folder no. # longer exists in the final image. WebNote to Python Programmers: To program with PETSc in Python you need to install the PETSc4py package developed by Lisandro Dalcin. This can be done by configuring PETSc with the option --download-petsc4py. See the PETSc installation guide for more details.

WebFeb 27, 2024 · Package petsc4py. This package is an interface to PETSc libraries. PETSc (the Portable, Extensible Toolkit for Scientific Computation) is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. It employs the MPI standard for all message-passing communication. WebPETSc provides a variety of matrix implementations because no single matrix format is appropriate for all problems. Currently, we support dense storage and compressed sparse row storage (both sequential and parallel versions), as well as several specialized formats. Additional formats can be added.
WebOct 22, 2024 · Then each of "import petsc4py_real", "import petsc4py_complex", "import petsc4py" would run in python. But then the internals of the module still refer to petsc4py. So while "import petsc4py_complex" will present get_config(), get_include() and init(), and petsc4py_complex.init() will run without error, at the same time it does not load up ... WebWe show below how to solve this problem with FEniCS using the VI solvers provided by PETSc To define the problem we need to specify the The functional to be minimized F, and its first and second directional derivatives The lower u L and upper u U bounds, here given by 0 and 1 respectively.
WebThis repository contains the scripts for building various Docker images for FEniCS. The built images are available at quay.io . These images are built with Python 3, using fenicsproject's official dev-env image For fenicsproject's official stable and dev images, which are built with Python 2, visit quay.io. Introduction WebPETSc for Fortran Users provides a discussion of the differences between using PETSc from Fortran and C, as well as several complete Fortran examples. Note to Python Programmers: To program with PETSc in Python you need to install the PETSc4py package developed by Lisandro Dalcin.
WebFeb 27, 2024 · Returns an instance :class:`Vec`, a PETSc vector from a DLPack object sharing the same memory. This operation does not modify the storage of the original tensor and should be used with contiguous tensors only. If the tensor is stored in row-major order (e.g. PyTorch tensors), the resulting vector will look like an unrolled tensor using row ...
