Re: [petsc-users] BuildSystem looks for libOpenCL.a

I spotted the problem. There is no libOpenCL.so in /usr/lib/x86_64-linux-gnu, only .so.1 and .so.1.0.0. That’s why OpenCL is not found. I have

Re: [petsc-users] BuildSystem looks for libOpenCL.a

Did you have a problem with the install? Are you concerned with self.liblist = [['libOpenCL.a'], ['-framework opencl'], ['libOpenCL.lib']] ? Even though only the .a library is listed that should be a stand-in for both the static and shared library and it should automatical

Hello! Is there a reason why the PETSc build system looks for libOpenCL.a, but not for libOpenCL.so on linux platforms? I have a machine with

Best to get latest petsc and build petsc4py along with petsc: For example: balay@ petsc-gpu-02: /scratch/balay$ wget -q https: //urldefense. us/v3/__https: //web. cels. anl. gov/projects/petsc/download/release-snapshots/petsc-3. 21. 2. tar. gz__;!!G_uCfscf7eWS!cU65HojMoX4qnDw9h2E_i8frWwq0jfbCE

Re: [petsc-users] Trying to develop my own Krylov solver

Make sure that you are using the latest PETSc if at all possible Also copy over a makefile from the cg directory (you do not need to edit any makefiles) You also need to add it to KSPRegisterAll() You will need to do make clean before running make all to compiler your new code.

[petsc-users] Trying to develop my own Krylov solver

Hi, Based on 'cg.c', I'm trying to develop my own Krylov solver (a projected conjugate gradient). I want to integrate this into my C++ code, where I already have an interface for PETSC which works well. However, I have the following questions : - Where am I sensed to put my 'cg_projected.c'

Re: [petsc-users] Modelica + PETSc?

Thank you, Matt. To clarify, I myself have no idea about the Modelica implementation/interface to solver, so I was looking for if any such efforts have been done so I could leverage them. -Ling From: Matthew Knepley Date: Monday, June 24, 2024 at 10:39 AM To: Zou, Ling Cc: petsc-users@mcs.anl.

Re: [petsc-users] DMPlexBuildFromCellList node ordering for tetrahedral elements

In my workflow, I was trying to use multiple mesh sources, and to achieve that, I converted them to an HDF5 file along with all other complementary information regarding my PDE. This approach seemed beneficial at first, but it's hard to manage now. (Also, I didn't know about DMPlexGenerate() :)
