The approaches of vector graphic library are OpenVG [1], AndroidVG
[2] and not-used GPU, and the approaches of Hadoop scheduler include
a first-come-first-serve manner, a fair scheduler [25] and our localityaware
scheduler. The results of the experiments show that the
CloudBook system can increase the performance of the OpenVG library
by 73%, reduce the execution time of file conversion by 50%–75%, and
improve the data hit ratio in cloud platform by 10%.
