HP2SIM meeting 2024-11-22

Topics discussed:

• The hand-written Poisson implementation, we should:

  • [x] Understand each of these functions and document them
  • [x] Check performance and run profiler ProfileView
  • [x] Read Julia Performance tips

• Technology plan (possible inclusion of PartitionedArrays.jl)

• Move PartitionedArrays.jl to a new organization

• Track performance of tests (BenckmarkTools) - high priority

[Cmurilochem]

HP2SIM meeting 2024-11-29

• [x] Implementation of benckmark tests, e.g.:

  • https://github.com/aviatesk/JET.jl/blob/master/.github/workflows/benchmark.yml
  • https://github.com/benchmark-action/github-action-benchmark

• [x] Implement caches and type-instability.

HP2SIM meeting 2024-12-06

• Merged https://github.com/GalerkinToolkit/GalerkinToolkit.jl/pull/147
• Merged https://github.com/GalerkinToolkit/GalerkinToolkit.jl/pull/149
• Merged https://github.com/GalerkinToolkit/GalerkinToolkit.jl/pull/155
• Look at https://github.com/JuliaDebug/Cthulhu.jl for tracking type-instability
• Split hand written into small pieces, e.g, https://github.com/GalerkinToolkit/GalerkinToolkit.jl/blob/example003_on_gpu/extensions/GalerkinToolkitExamples/src/example001.jl
• CI using GPUs; as an example, look at https://github.com/Ferrite-FEM/Ferrite.jl/blob/master/.buildkite/pipeline.yml

HP2SIM meeting 2025-01-24

• Want to have a workshop at which we invite anyone using Julia in the FEM space to come and give presentations. The last 2 slides of the presentation should be "Where can we collaborate?". It doesn't make sense for everyone to work on everything, we can probably reuse each other's packages where possible (e.g. ParitionedArrays is already used by Gridap etc.)
  • Ask at escience if there is any help we can get with workshop logistics
  • Do we have a workshop budget in the call? Sounds like probably not (Edit: We do - see the award letter))
• Start work on integrating GPU-optimized solvers to PartionedArrays.jl
• Add benchmarking, zenodo integration etc. to PartitionedArrays
  • wrap a GPU solver
  • direct method, solver wrapper, (CUSPARSE.jl) (see cuDSS?) -> CUDA.jl?
  • motivates infra for GPU testing
  • continuous integration for GPUs - look into DAS option - ask GPU team about it
• Work more on documentation of GalerkinToolkit
  • Ask Johann about making makie plots look better
  • Add a paraview example
• Goodbye @Cmurilochem 😢

HP2SIM meeting 2025-03-14

Priorities:

• Focus on infrastructure for GPUs
  • Continuous Integration for GPUs
  • Wrap a solver (to have something to test)
• Improve Makie plotting quality (especially shadows) - Speak to Johan
• Workshop (date not yet agreed)
  • Probably at the VU
• Added (fverdugo): Simplify type signatures in GalerkinToolkit.
• Benchmark tracking in PartionedArrays (start with Sparse Matrix product)
• Documentation (in GalerkinToolkit and PartionedArrays/Solvers)
• Developer documentation (especially for GPU solver wrapper)

Note: Look at other projects (e.g. CUDA.jl) to see how the GPU testing happens Consider getting a logo designed for GalerkinToolkit. Then print some stickers (also for PartionedArrays) to hand out at workshop and other promotion events.
