RDMA中QP共享方法的整理


下面总结了一下已有论文中给出的qp共享的方法。

OSDI16- FaSST: Fast, Scalable and Simple Distributed Transactions with Two-sided (RDMA) Datagram RPCs

FaSST [24] shares QPs among threads, which subsequently lowers the CPU efficiency and performance due to the lock contention of QPs between threads.

An alternative heuristic is the inclusion of a dedicated proxy thread that manages all receive and send requests [41]. However, switching to/from a dedicated proxy thread increases latency. Furthermore, it is difficult to saturate the full network bandwidth with a single thread. Moreover, the proxy solution is not transparent to the underlying RDMA libraries.

之前我的准则是绝对不在虚拟世界上花钱,所以游戏从来不充钱,软件全部用破解版,科学上网找各种免费的途径。但是渐渐地我觉得我们应该尊重作者的创造成果,支持作者开发出更好的软件,同时付费能够节省大量的时间精力,免去找破解软件或服务的繁琐。因此我开
