Bamboo: A Domain-Specific Language for PDE Solvers on Structured Grids

Introduction

from bamboo import Grid, Stencil

grid = Grid(shape=(100, 100))
@Stencil
def laplace(u):
    return 0.25 * (u[1, 0] + u[-1, 0] + u[0, 1] + u[0, -1])

Bamboo is a high-level domain-specific language (DSL) designed to simplify PDE solver development on structured grids. It abstracts away parallelization and optimization, allowing domain scientists to focus on physical algorithms rather than low-level performance tuning.

Embedded in Python, Bamboo provides an intuitive syntax for defining computations in terms of grids, discretization, and time integration. The back-end generates optimized code for CPUs (including Huawei Kunpeng), GPUs/DCUs, and next-generation Sunway architectures, ensuring performance portability across platforms.
