FIESTA 2：可并行化的多循环数值计算
FIESTA 2: parallelizeable multiloop numerical calculations
摘要：
FIESTA程序已完全重写。现在它不仅可以作为数值计算Feynman积分的工具，而且可以利用扇形分解和Mellin-Barnes表示在动量和质量的限制下自动展开Feynman积分。其他重要的改进代码是完全并行化（甚至多台计算机），高精度的算术（允许计算积分，这是以前无法做到的），新的积分器和斯佩尔部门作为一种策略，评估更一般的参数积分的可能性。
英文摘要：
The program FIESTA has been completely rewritten. Now it can be used not only as a tool to evaluate Feynman integrals numerically, but also to expand Feynman integrals automatically in limits of momenta and masses with the use of sector decompositions and Mellin-Barnes representations. Other important improvements to the code are complete parallelization (even to multiple computers), high-precision arithmetics (allowing to calculate integrals which were undoable before), new integrators and Speer sectors as a strategy, the possibility to evaluate more general parametric integrals.
