STTR Phase I: Splintered Topologically Close-Packed (TCP) Offload Engine for Grid Computing and Bandwith-Delay Product (BWDP)

这一小型企业技术转移(STTR)第一阶段研究项目旨在应对具有极端带宽延迟产品的网络所面临的挑战，例如美国研究机构与瑞士类似研究机构之间的40Gbps网络链路。需要为网络中的批量数据传输提供所需的端点资源，以确保以经济高效的方式实现高性能。该研究项目适应这样的高性能网络，如数据速率从10Gbps扩展到40Gbps，并提供与当前和未来版本的GridFTP的兼容性。此外，这项研究还根据最新的出版物，通过使用一种新的卸载引擎和分离的TCP实现来解决这些挑战。与完全卸载方法不同，拆分的TCP使用部分卸载和真正的零拷贝传输来控制NPU上所需的资源。在这个项目中，将使用低成本、高性能的FPGA子系统来研究卸载引擎架构，并对其进行推导和模拟。使用NPU开发套件，将测试拆分性能，以确定哪些卸载是最优的。该研究项目的成功结果将极大地促进用于网格计算的卸载引擎的技术水平。目前的应用包括满足电子科学界对网格计算的可扩展卸载引擎的需求，这是适应具有多通道10 Gbps至40 Gbps链路的系统所必需的，同时支持GridFTP的当前和未来版本。其他应用包括利用我们的开源固件，将我们的超高速分离式TCP卸载引擎用于网格和集群计算。其他产品应用包括TeraGrid、网格集群广域网和刀片服务器。

This Small Business Technology Transfer (STTR) Phase I research project addresses the challenges of networks with extreme bandwidth delay products such as a 40Gbps network link between a US research facility and a similar research facility in Switzerland. Bulk data transfers in the networks need to be provided the endpoint resources required to ensure high performance in a cost effective manner. This research project accommodates such high performance networks, as data rates scale from 10 Gbps to 40 Gbps, and also provide compatibility with present and future versions of GridFTP. Additionally, the research addresses the challenges through the use of a novel offload engine with a splintered implementation of TCP based on the latest publications. In contrast to full offload approaches, splintered TCP uses partial offload and true zero-copy transfers to control the resources needed on the NPU. During this project, the offload engine architecture will be investigated using low-cost, high-performance FPGA subsystems that will be derived and simulated. Using an NPU development kit, the splinter performance will be tested to determine which offloads are optimal.Successful results from this research project will significantly advance the state of the art for offload engines used in grid computing. Immediate applications include accommodating the e-science community's need for scalable offload engines for grid computing, that is required to accommodate systems with multiple channel 10 Gbps links through 40 Gbps, while supporting present and future versions of GridFTP. Other applications include the use of our ultra high-speed Splintered TCP offload engines for Grid and cluster computing, utilizing our open source firmware. Additional product applications include the TeraGrid, Grid Cluster WANs, and blade servers.
