System Status Aware Hadoop Scheduling Methods for Job Performance Improvement

A Review on HADOOP MAPREDUCE-A Job Aware Scheduling Technology

Proposed Pilot Pattern Methods for Improvement DVB-T System Performance

Recently, orthogonal frequency division multiplexing (OFDM) has been extensively used in communications systems to resist channel impairments in frequency selective channels. OFDM is a multicarrier transmission technology in wireless environment that use a large number of orthogonal subcarriers to transmit information. OFDM is one of the most important blocks in digital video broadcast-terrestr...

Job Attentive Scheduling Algorithm in Hadoop

In recent years cloud services have gained much attention as a result of their availability, scalability, and low cost. One use of these services has been for the execution of scientific workflows as part of Big Data Analytics, which are employed in a diverse range of fields including astronomy, physics, seismology, and bioinformatics. There has been much research on heuristic scheduling algori...

Research on Job Scheduling Algorithm in Hadoop

On the basis of researching Fair Scheduling Strategy deeply in Hadoop cluster,the Node Health Degree is defined by constructing the relationship function between node load and job fail rate, and a job scheduling algorithm based on Node Health Degree is proposed in this paper. Nodes are grouped, according to Node Health Degree, into three categories in order to assign corresponding job in accord...

Power-Aware Parallel Job Scheduling

Recent increase in performance of High Performance Computing (HPC) centers has been followed by even higher increase in power consumption. Power draw of modern supercomputers is not only an economic problem but it has negative consequences on environment. Roughly speaking, CPU power presents 50% of total system power. Dynamic Voltage Frequency Scaling(DVFS) is a technique widely used to manage ...
