We develop a visual tool for parallel computing monitor and evaluation,using lm-sensors for hardware information,advantage proc file system for node load(information) and recording the program running process s file by MPE,which is capable of showing all this informationin graph mode.

And then the LM method and specific steps of evaluation for the system availability and storage period are given.

Application of LM arithmetic in groundwater regime forecast;

Accordingly, this paper comes up with acoustic porosity for predicting reservoir by LM arithmetic based on neutral network, whose main procedures comprise: selection and pre-transaction of samples, design of network structure, network training of LM arithmetic based on Matlab neutral network toolbox programming and prediction of acoustic porosity.
