发明实施例
本发明的实施方式
[0031] 结合实施例说明本发明的具体技术方案。
[0032] 如图 1所示, 分子力场参数生成的计算任务管理分析系统, 包括计算结果分析 模块和计算任务管理模块, 计算结果分析模块与计算任务管理模块连接, 计算 任务管理模块通过云计算接口与力场构建计算服务器连接。 所述的计算结果分 析模块包括交互式分析、 自定义分析、 自动化分析; 计算任务管理模块包括计 算任务提交、 图数据结构视图、 计算任务模板设置、 计算任务结果回收、 计算 路径设置; 计算任务结果回收与计算结果分析模块连接, 计算任务提交与云计 算接口连接。
[0033] 针对不同的使用场景, 本系统可以应用手动分析和自动化分析两种模式, 其中 手动分析又分为交互式分析和自定义分析; 通常在需要进行大批量计算时应用 自动化分析; 在系统自带分析模板可以满足分析需要时使用交互式分析; 需要 个性化分析时使用自定义分析, 如图 2所示。
[0034] 应用于手动分析的具体使用流程如图 3所示;
[0035] 应用于自动分析的具体使用流程如图 4所示;
[0036] 下面对图中的功能模块和流程进行说明。
[0037] 通常一次完成的分子力场的构建过程是需要多次分步计算, 手动分析的使用流 程以其中一次典型的分子力场构建计算任务的提交到分析为例。
[0038] 一般情况下会选择一批同类分子作为力场构建拟合过程的输入, 输入后, 要完 成以下步骤:
[0039] ( 1) 选择分子力场构建计算模板
[0040] 对于不同类型的分子, 提交分子力场构建计算任务时会需要调整不同的参数, 本系统能够根据输入的分子类型通过机器学习的算法自动推荐计算参数, 同时 使用者也可以根据需要对参数进行调整, 以适应自身需求。
[0041] (2) 选择计算任务提交平台并提交计算
[0042] 本系统支持将计算任务提交到本地计算服务器或集群、 超算中心、 云服务。 通 常力场构建工作者都是通过本地计算服务器或超算中心来计算, 而随着云服务 的发展, 云服务显然可以提供更大的算力, 以提升构建速度。 但一般的科研机 构不具备对云服务的开放接口开发能力, 通过本系统可以克服该障碍。
[0043] (3) 回收计算结果
[0044] 本系统支持在计算任务完成后, 回收计算结果数据至本地, 同时处于安全考虑 , 支持清除服务器或者云端的计算数据, 同时备份重要过程数据至本地。
[0045] 计算任务回收后, 会按照力场参数的图数据结构并以力场参数为索引展示, 如 图 5
[0046] (4) 结果分析
[0047] (a) 交互式分析
[0048] 根据不同的计算模板, 系统会使用对应计算模板的交互式分析组件来构建计算 结果的分析报告。 以常规的分子力场构建结果分析模式为例, 会包括分子力学 方法与量子力学方法计算出的能量、 力、 结构参数 (键长、 键角、 二面角、 反 常二面角等) 的比对。 利用交互式分析功能, 可以很快读取出离群异常点的所 有数据, 并快速定位到异常数据的分析图, 以某散点图的效果为例, 见图 6; 另 夕卜, 还可以通过一些计算函数来批量筛出离群异常点。
[0049] (b) 自定义分析
[0050] 通常使用交互式分析自带的分析功能就足以满足常规分析需求, 但也存在使用 者会需要分析其他数据的情况, 这时可以使用自定义分析功能来导入需要的数 据来进行分析。 由于计算任务提交的分子数据也是基于分子构象的编号为主索 引的, 因此可以按照构象拿到每个构象的属性或者计算结果。 自定义分析支持 多种图表类型, 除常见的散点图、 折线图、 柱状图、 饼图外, 还支持箱线图、 小提琴图等对偏差和分布敏感的图表, 帮助使用者更清晰地发现数据的问题。
[0051] 如果使用自动分析功能, 如图 4所示, 则可以通过计算路径和分析标准的设定 来连续自动执行, 具体步骤和相关的功能模块介绍如下:
[0052] A设置分子集合的计算路径
[0053] 本系统支持多任务并行提交, 需要提前设置好分子计算的路径。
[0054] 例如一批分子可能有 x个烷烃、 y个醇醛酮类、 z个含氮化合物。 需要先对 x个烷 烃进行三次拟合计算, 完成再同时对 y个醇醛酮类和 z个含氮化合物并行做三次拟 合计算。 这时的路径如图 7所示。
[0055] 需要在每一个路径上设置需要计算的分子、 计算任务的模板、 自动化分析的标
准。 其中自动化分析的标准用于判断当前任务的拟合过程是否达到要求, 如果 达到要求则进行下一步计算; 如果未达到则中断进程并通知使用者重新设定计 算条件。
[0056] B选择计算任务提交平台并提交计算
[0057] 同交互式分析。
[0058] C回收计算结果
[0059] 同交互式分析。
[0060] D自动化分析
[0061] 本系统在计算结果回收后, 由于之前设置了自动分析标准, 可以对任务计算结 果进行自动化分析, 并留存分析结果, 符合要求的则会继续计算直至完成。
[0062] 以一次完整的分子力场构建过程的情况为例来说明效益。
[0063] 某机构科研人员计划用 10000个分子来构建一套新的分子力场。 其中计划分 100 次任务, 每次 100个分子进行力场拟合来构建力场。
[0064] 通过使用本系统, 该人员可以将 100次任务提前进行计算路径规划, 并利用系 统的自动匹配模板的功能快速设置计算模板, 然后提交到云上计算, 而如果使 用传统方式则需要分次提交 100次。 由于采用了自动化分析, 任务完成后可以直 接继续下一任务, 充分利用了空隙的时间; 另外云上算力更强大, 计算速度要 更快, 因此大大提升了分子力场的构建效率。
[0065] 当计算完成后, 可以在计算任务管理界面清晰地查看分子力场的构建路径、 数 据结构和计算任务的分布以及总量, 能全景地了解此次分子力场构建的全局信 息。
[0066] 对于计算结果的交互式分析, 如图 6中, 可以直接查看任一点的相关信息和分 子构象, 还能帮助使用者计算使用了同类参数的其他构象, 用于观察是否都有 异常; 还可以利用一些计算函数通过对某些值的计算, 快速筛出一批异常分子 , 大大提高了使用者的效率。
[0067] 另外, 如有特殊的需要, 还可以使用自定义分析功能, 满足了使用者的个性化 需求。
