With the acceleration of computing speed of supercomputers,our demand of network telecommunication performance is increasing as well.Once the network telecommunication performance is not compatible of computer computing speed,the computing speed of supercomputers will shrink enormously.Thus,the research of network card is of great importance recently.In order to shorten the development cycle of supercomputer network card and test the performance more conveniently,establish HPC(High performance computing)inter-communication simulation environment has attracted huge attention.Within HPC inter-communication simulation environment,available network interface virtualization technique cannot accomplish the network pattern simulation of next-generation supercomputers.At the same time,there is short of related research of performance improvement testing and simulation of network interface virtualization technique.Consequently,we mainly focus on the research of network interface virtualization technique,then design and implement suitable technical approach.This paper introduces the design and implementation of the HPC(High performance computing)inter-communication simulation environment firstly.Then we come up with a new SRDMA virtualization technique of network interface that can build network communications for virtual machine with RDMA pattern on the NIC adapter which cannot use RDMA pattern by itself.This technique meets the supercomputer needs of adapter development with network pattern simulation.At the same time,we construct a system with test and analyze function for virtualization technique of network interface.The test and analyze system includes different kinds of distributed computation algorithm and controls different parameter of distributed computation.And we use test and analyze system to test and analyze different kinds of network interface virtualization technique.In the test and analyze platform,we come up with a data sifting algorithm based on confidence interval which can keep effective test data precisely to ensure its accuracy and reliability.The experiment results show that SRDMA virtualization technique of network interface can satisfy the supercomputer needs of adapter development with network pattern simulation.At the same time,after implementing selection algorithm on data,the results illustrate more precisely the network performance of HPC inter-communication simulation environment.Moreover,by analyzing data of the network performance,we can obtain the matching relationship of network virtualization technique performance and computing ability of simulation environment.
