Inter-application I/O contention and performance interference have been recognized as severe problems. In this work, we demonstrate, through measurement from Titan (world's No. 3 supercomputer), that high I/O variance co-exists with the fact that individual storage units remain under-utilized for the majority of the time. This motivates us to propose AID, a system that performs automatic application...
In our case, an original television (TV) broadcasting monitoring system is proposed and then implemented in order to meet the urgent requirements for rapid development of radio and television industry. The monitoring system involves four primary sub-modules, the functions of which are respectively described as image extraction, network transmission and storage, dispatching and configuration, data...
Offering better performance for random access compared to conventional hard disks and providing larger capacity and lower cost than DRAM, NAND flash based SSDsare integrated in server storage hierarchy as a second tier of disk cache between DRAM and disks for caching more data from disks to meet the increasingly intensive I/O demands. Unfortunately, available hybrid storage architectures cannot fully...
Formative assessment is an important method to control the quality of the learning process. In this paper, a framework for the formative assessment management system is presented. This three-layer system framework is based on the J2EE technologies. The principles of data structure design were discussed. We discuss formative assessment based on fuzzy evaluation in details which included establish the...
