Many users make many kinds of experiments and produce enormous data in MLF, J-PARC. Through these two years, we have developed the several items in the MLF computing environment. The developments of the remote access in MLF are the monitoring method of the currently-executing experiment status in each instrument via Web and the web-based data reduction and visualization with the database. The automatic measurements with the Experiment Scheduler automatically manage the measurement conditions and raw data on the database. By using them, we can analyze the data multi-dimensionally as well as reuse in the new automatic measurements. We have introduced the universal signal event recording board for transient phenomenon measurement. We can make the experiments which dynamically changes the measurement conditions. The MLF standard data acquisition software has been updated from 32-bit architecture to 64-bit and the data analysis library is an increase in I/O speed more than 10 times.
