摘要
针对流媒体数据 ,结合网络磁盘阵列的工作特点 ,提出了一种并行流水生产者消费者模型 .该模型采用并行技术 ,通过截断 SCSI命令的 I/ O周期来流水重叠系统中多个数据请求的磁盘 I/ O操作和 CPU计算 ,最大限度地提高了系统的并行性 .测试结果表明 。
Proposed a parallel pipeline schedule algorithm for the streaming media system based on the character of Net RAID and producer consumer model. This algorithm adopts parallel technology, overlaps the disk I/O and CPU computation, and improves system parallelism to the maximum. Theoretical analysis and test results show that the performance of Net RAID system is upgraded greatly with this algorithm in place.
