摘要：Constructing a system with traditional resources, based on the concept of high-performance computations (HPC) and data processing in the cloud, fully reveals new addressing problems. In the course of processing the data, it discovers many other unexplored scientific problems. One of these problems is to reduce the network expenditures on a virtual cluster in the cloud with HPC. In order to solve this problem, the work presented proposes a mechanism of simplified communication (SCM) to optimize the intra-cluster network performance, which intercepts packets at the level below that of network, and verifies whether it is meant for a coresident virtual machine. Compared with TCP, the introduced protocol of simplified communication (SCP) makes it possible to avoid the slow start phase, and to use a smaller header for a data packet, which improves the intra-domain and extra-domain throughput. To implement SCM inside the system, we also integrated XenLoop. A dispatched packet is sent through the FIFO channel, which is opened by XenLoop. This realization supports binary compatibility for the applications that use a standard socket interface. Throughput of the intra-domain communication in the system with SCM improves by about one and a half, while relative time of a reference test with a set of NAS-tags is lower. Experimental comparison of indicators for SCP and a protocol of remote memory access (RMAP) shows that SCP is 7.8–7.9 % faster than RMAP.
