The field of Computational Relativistic Astrophysics has arrived at the verge of predictive modeling of many observed and expected sources of radiation. As the community strives to increase the realism in the employed physics models, progress is severely hindered by the complexity and difficulties in using computational methods at large scales. As hardware architectures evolve, many formerly highly efficient algorithms can exploit only a fraction of the power of newer hardware, and novel algorithms need to be developed and refined.

计算相对论天体物理学领域已经到达了对许多观测到的和预期的辐射源进行预测建模的边缘。随着社区努力提高所采用的物理模型的真实性，进展受到大规模使用计算方法的复杂性和困难的严重阻碍。随着硬件架构的发展，许多以前高效的算法只能利用新硬件的一小部分功能，需要开发和改进新的算法。
