Materials and Life science Facility (MLF) of Japan Proton Accelerator Research Complex (J-PARC) will provide world's highest intensity pulsed beams of neutron and muon. The construction will finish at the end of 2007. Because it is expected that generate gigabyte order time-of-flight data will be produced per one experiment, system developments and engineerings of computers are crucial as well as instrument hardware designs to make really good use of all the data. At first, we defined very simple components that should work correctively to realize the computing environment for MLF; experiment, analysis, simulation, database, user interface (we call this as working desktop), graphic, network (collaboratory), and security components. The working desktop will interconnect between each component. This environment will provide common functionalities between instruments. Instrument specific functions expected to be developed and connected through the working desktop component. The development of the analysis component is progressing with C++ and it was named as Manyo-lib. The working desktop component were realized with Python because of Python's scientific abilities such as wrapping C, C++, and Fortran, graphic packages, scientific packages like Scipy and so on. We haven't completed whole the development but the analysis component and working desktop components are consistently working now. In this presentation, we will present our conceptual designs of each components as well as the details of the analysis component.
