As the number of nodes in high-performance computing environments keeps increasing, faults are becoming common place. Reactive fault tolerance (FT) often does not scale due to massive I/O requirements and relies on manual job resubmission. This work complements reactive with proactive FT at the process level. Through health monitoring, a subset of node failures can be anticipated when one's health...
In view of many issues from the present coal gas detection systems on operation parameters, data point table-based a kind of remote multi-stage monitoring & management system frame for the coal mine gas is designed. Structure of data point table, file format of data gathering, data format of data transmission and producing and uploading basic data for remote monitoring system are integrated in...
In-field calibration of sensor devices is known to be a challenging problem because there is often no access to a controlled signal field and/or a pre-calibrated device to provide the ground truth. Nonlinear characteristics of sensor devices make the calibration problem even harder. In this paper, we describe two blind calibration schemes for nonlinear mobile sensor nodes: nullspace based calibration...
