OpenMP Fortran and C programs for solving the time-dependent Gross-Pitaevskii equation in an anisotropic trap

We present new version of previously published Fortran and C programs for solving the Gross-Pitaevskii equation for a Bose-Einstein condensate with contact interaction in one, two and three spatial dimensions in imaginary and real time, yielding both stationary and non-stationary solutions. To reduce the execution time on multicore processors, new versions of parallelized programs are developed using Open Multi-Processing (OpenMP) interface. The input in the previous versions of programs was the mathematical quantity nonlinearity for dimensionless form of Gross-Pitaevskii equation, whereas in the present programs the inputs are quantities of experimental interest, such as, number of atoms, scattering length, oscillator length for the trap, etc. New output files for some integrated one- and two-dimensional densities of experimental interest are given. We also present speedup test results for the new programs. Previous versions of this program (AEDU_v1_0, AEDU_v2_0 and AEDU_v3_0) may be found at dx.doi.org/10.1016/j.cpc.2009.04.015, dx.doi.org/10.1016/j.cpc.2012.03.022 and dx.doi.org/10.1016/j.cpc.2015.12.006 respectively.我们发布了此前已发表的Fortran与C语言程序的新版本，用于求解接触相互作用下玻色-爱因斯坦凝聚态（Bose-Einstein condensate）的格罗斯-皮塔耶夫斯基方程（Gross-Pitaevskii equation），支持一维、二维与三维空间维度下的虚时与实时间求解，可得到定态与非定态两类解。为降低多核处理器上的运行耗时，我们基于开放式多处理（Open Multi-Processing, OpenMP）接口开发了并行化程序的新版本。此前版本的程序输入为格罗斯-皮塔耶夫斯基方程无量纲形式的非线性数学参数，而本版本程序的输入则为实验中关注的物理量，例如原子数、散射长度、囚禁势的振荡长度等。同时提供了若干实验关注的积分形式一维与二维密度的新输出文件。我们还给出了新版本程序的加速测试结果。该程序的此前版本（AEDU_v1_0、AEDU_v2_0与AEDU_v3_0）可分别在以下链接获取：dx.doi.org/10.1016/j.cpc.2009.04.015、dx.doi.org/10.1016/j.cpc.2012.03.022及dx.doi.org/10.1016/j.cpc.2015.12.006。
