  4. Functions of Data Processor • Estimation of an attribute value and deviation (predictability) for load-related attributes: number of free job slots, queue length, job waiting time. • Detection of a resource failure/recovery periodicity. • Calculation of reliability-related parameters: time between failures, recovery time. • Estimation of a next resource failure time based on mean TBF and TBF deviation. • Estimation of a next resource failure period based on mean TOF and TOF deviation. • Determination of a “failure-safe” resources for a specified job.

  6. Final Results • Complete software suite is developed • Installed and working at PNPI • 5.7 Gb of statistical data collected up to now • Open to future improvements (integration with new MW and so on)
