NumPy 2.0 removed the deprecated np.trapz alias in favor of np.trapezoid. This commit updates all occurrences across the codebase: - tests/test_inputs.py - zeus21/cosmology.py - zeus21/correlations.py - zeus21/sfrd.py - zeus21/UVLFs.py - zeus21/xrays.py Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Because CLASS stores state in C globals, fork()-based multiprocessing can corrupt it. This commit adds a process-level cache keyed by cosmological parameters and os.getpid(), so each spawned worker only initializes CLASS once. Subsequent calls reuse the cached object, giving a large speedup for Monte Carlo and inference workloads. Also included: - examples/benchmark_multiprocess.py: runnable before/after benchmark - README updates with multiprocessing guidance Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
