v0.11.1

Changing GPU runtime behavior to allow for code profiling for M&C 2025 papers

What's Changed

• Merge pull request #248 from CEMeNT-PSAAP/dev (Making dev up to date to main) by @ilhamv in #249
• GPU Sub-batching + Opt-in caching by @braxtoncuneo in #250
• pyproject.toml for v0.11.1 by @jpmorgan98 in #251
• v0.11.1 by @jpmorgan98 in #252

Full Changelog: v0.11.0...v0.11.1

v.0.11.0

• AMD and NVIDIA GPU functionalities #241 by @braxtoncuneo.
• Improved CSG geometry modeling #222 by @ilhamv: intersection, union, complement
  • Reverse Polish Notation algorithm is used
  • Cell input changes. Cell region is now defined with boolean operations of regions or surface halfspaces. Previously, it was defined as a list of surface halfspaces that were limited to intersection operation.
• Improved geometry tracking #238 by @ilhamv: replace particle shifting with direction checking to treat spatial coincidences, refactor geometry-related source code to submodules, better coincident event treatment, better unit testing, non-stopping tally mesh
• Improved tally: refactor tally structure into long 1D array #227 and density score #245 by @ilhamv, mesh tally decomposition #227 by @alexandermote,
• Improved universe modeling #238 by @ilhamv : universe rotation and translation, universe-filled cell
• Add and set splitting roulette as default population control (#242) for complete reproducibility on GPU runs due to concurrent tracking of the secondaries by @braxtoncuneo and @ilhamv.
• iQMC update #223 by @spasmann: batching algorithm, improved readability and maintanibility
• Visualizer update
  • A 2D lightweight visualizer is introduced #240 by @ilhamv .
  • The 3D Ngsolve visualizer is removed #245. It is and will be replaced with alternatives that have fewer dependencies.
• Pre-commit hook for automatic black-styling
• The moving surface capability is temporarily removed (#238). It will be better reimplemented in the next version.
• Verification test is moved (#238) to https://github.com/CEMeNT-PSAAP/MCDC-VVP
• Having portability on CPUs, NVIDIA GPUs, and AMD GPUs, this version will be the first named version whose performance test results are recorded in https://github.com/CEMeNT-PSAAP/MCDC-VVP
