提出了一种新的通信模型，称为PlogPT模型，用于预测计算节点使用TCP/IP通信的商用集群的通信性能。该模型对PlogP模型进行了扩展，以考虑网络交换机中瓶颈链路带来的带宽变化以及通过TCP/IP处理分组重传的延迟。网络交换机被建模为二叉树连接。为了验证PlogPT模型的建模能力，对两种全对全通信算法的执行时间进行了估计，并与实际执行时间和PlogP模型的执行时间进行了比较。PlogPT模型比现有模型更准确地预测了这两种算法的执行时间。
A new communication model, called the PlogPT model, is proposed to predict communication performance in a commodity cluster where computing nodes communicate using TCP/IP. This model extends the PlogP model in order to consider the variation of bandwidth brought about by bottleneck links in network switches and the delay of packet retransmission by TCP/IP handling. Network switches are modeled as binary tree connections. To demonstrate the PlogPT modelpsilas modeling capability, the execution time of two all-to-all communication algorithms are estimated and compared with the actual execution time and that of the PlogP model. The PlogPT model predicts the execution time of those two algorithms more precisely than the existing model.
