# Cycle Goal

**Meaningful performance baseline for the Dycore granule**

ICON-EXCLAIM running with ICON4Py and GT4Py-DaCe `main` branches, with minimal Python overhead and meaningful performance benchmarks. This also requires finishing the combined programs and merging all the half-finished features like `concat_where`, and complete the benchmarking infrastructure to support writing more optimizations in next cycles.
