Title A Cloud System Based on RDMA and FPGA
Abstract
In recent years, more and more computing systems are deploying some kind of accelerators. FPGA, as a programmable hardware accelerator, has significantly boosted the overall performance of the cloud system. At the meantime, RDMA (Remote Direct Memory Access)，a high performance network, provide service to users with high throughput and low latency . Based on basic RDMA measurement study on multiple tenants, we describe a mechanism for virtualizing remote FPGA resources in the cloud using RDMA network, enabling the transfer of data between heterogeneous computing nodes in the cloud with high throughput and low latency. The prototype system has been implemented in IBM CRL OpenStack-based cloud system. Preliminary experimental results demonstrate not only the feasibility of deployment of FPGA and RDMA in the cloud system， but also the effectiveness and potential usefulness of the services to users.
Keywords： Remote Direct Memory Access (RDMA), Field Programmable Gate Arrays (FPGA), Cloud System, Accelerator and Virtualization.
