Researchers at McGill University have developed a novel Finite Element Method (FEM) technology referred to as Finite Element Gaussian Belief Propagation (FGaBP). FGaBP recasts the FEM as a probabilistic inference problem, substantially increasing the speed and robustness of FEM software. FGaBP breaks the FEM into distributed computations that can be efficiently executed in parallel on multicore and manycore CPUs. Initial implementations of FGaBP for static electromagnetic applications have shown near-linear scalability with the number of parallel cores and significant speedup compared to widely used open-source FEM libraries.

麦吉尔大学的研究人员开发了一种新的有限元技术，称为有限元高斯信念传播(FGaBP)。FGaBP将有限元问题重塑为概率推理问题，大大提高了有限元软件的速度和健壮性。FGaBP将有限元分解为分布式计算，可以在多核和多核CPU上高效地并行执行。与广泛使用的开源有限元库相比，FGaBP在静态电磁应用中的初步实现已经显示出随着并行核心数量的近线性可伸缩性和显著的加速比。
