论文摘要
作为跨越边缘，云和HPC系统工作流程的一部分，将混合环境合并的需求越来越大。在这样的云和HPC的融合环境中，容器开始发挥更为突出的作用，并将其网络基础架构随身携带。但是，目前的工作体系表明，通常用于在物理主机上连接容器的容器覆盖网络不适合HPC环境。他们倾向于施加明显的开销和噪音，从而导致对同一主机上的共同处理的性能和干扰降解。本文着重利用新颖的硬件类别，数据处理单元，将覆盖网络的网络堆栈从主机转移到DPU上。我们打算表明，这种辅助卸载是可能的，它将导致主机节点上的开销减少，从而改善运行过程的性能。
There is an increasing demand to incorporate hybrid environments as part of workflows across edge, cloud, and HPC systems. In a such converging environment of cloud and HPC, containers are starting to play a more prominent role, bringing their networking infrastructure along with them. However, the current body of work shows that container overlay networks, which are often used to connect containers across physical hosts, are ill-suited for the HPC environment. They tend to impose significant overhead and noise, resulting in degraded performance and disturbance to co-processes on the same host. This paper focuses on utilizing a novel class of hardware, Data Processing Unit, to offload the networking stack of overlay networks away from the host onto the DPU. We intend to show that such ancillary offload is possible and that it will result in decreased overhead on host nodes which in turn will improve the performance of running processes.
