Materials and Life Science Facility (MLF) of Japan Proton Accelerator Research Complex (J-PARC) will provide one of the highest intensity pulsed neutron and muon beams. The MLF computing environment design group organizes the computing environments of MLF and instruments. It is important that the computing environment is provided by the facility side, because experimental and output data formats, the analysis operators and also data analysis strategy want to be shared among many instruments in MLF. The C++ class library, named Manyo-lib, is a framework software for developing data-reduction and analysis softwares. The framework is composed of the class library for data reduction and analysis operators, network distributed data processing modules and data containers. The class library is wrapped by the Python interface created by SWIG. All classes of the framework can be called from Python language, and Manyo-lib will be cooperated with the data acquisition and data-visualization components through MLF-platform which is working on Python language. Raw data in event-data format obtained by data acquisition systems will be converted into histogram format data on Manyo-lib in high performance, and data reductions and analysis is performed with user-application softvvares developed on Manyo-lib. We enforce standardization of data containers with Manyo-lib, series of fundamental data containers in Manyo-lib have been designed and developed. Experimental and analysis data in the data containers can be converted into NeXus file. Manyo-lib is the standard framework for developing analysis software in MLF, and prototypes of data-analysis softwares for each instrument are being developed by the instrument teams.

日本质子加速器研究综合体（J-PARC）的材料和生命科学设施（MLF）将提供最高强度的脉冲中子和μ子束。多边基金计算环境设计小组负责组织多边基金和仪器的计算环境。计算环境由设施方提供是很重要的，因为实验和输出数据格式、分析运算符以及数据分析策略都希望在多边基金的许多仪器之间共享。C++类库Manyo-lib是一个用于开发数据处理和分析软件的框架软件。该框架由数据约简与分析算子类库、网络分布式数据处理模块和数据容器组成。类库由SWIG创建的Python接口包装。该框架的所有类都可以从Python语言调用，Manyo-lib将通过基于Python语言的MLF平台与数据采集和数据可视化组件协作。数据采集系统获得的事件数据格式的原始数据将在Manyo-lib上以高性能转换为直方图格式的数据，并使用在Manyo-lib上开发的用户应用软件进行数据简化和分析。利用Manyo-lib对数据容器进行标准化，设计并开发了Manyo-lib中的一系列基础数据容器。数据容器中的实验和分析数据可以转换为NeXus文件。Manyo-lib是在多边基金中开发分析软件的标准框架，各仪器小组正在为每种仪器开发数据分析软件原型。
