Unfortunately, because not all of the problem can be parallelized and there's overhead in managing the processors, the speedup is quite a bit less. 不幸的是,并非所有的问题都可以并行化,而且还有管理处理器的开销,所以速度的提高并没有这么大。
We proposed a fast slide mark compact algorithm, which reduces the overhead by mark bit table, live block pool and offset table. 本文提出一种快速的滑动标记缩并算法,它通过位图、活块池和块内偏移表来简化算法,大大的降低了开销。
In this application model, the protocol has comparative performance with unicast routing protocols in packet delivery rate, less transmission overhead than the unicast and other multicast routing protocol and less control bit overhead. 在该应用模型下,协议的分组递交率性能与单播路由协议相当,发送开销比单播和其他组播路由协议大大减少,控制比特开销也较低。
The simulation results show that this algorithm can reduce the amount of computation greatly; meanwhile, the overhead to transfer the bit allocation vector is less. 该算法可以使自适应分配算法的计算量大大降低,同时也减小了传送比特分配向量所需的开销。
