介紹
Myri-10G Myri-10G 是 10 千兆位乙太網與 HPC HPC 技術的集成體。 將 NIC 連線埠連線至 10 千兆位乙太網交換機,即可實現高達每秒 9.8 千兆位的數據傳輸速度。 將 NIC 連線至一個 10G Myrinet 交換機,並提供一種網路功能,支持相同的軟體接口,如乙太網,以及用於套接字、MPI 和 DAPI 的低時延、核心旁路 API。 Myri-10G 能與 10 千兆位的乙太網合用,以連線 IP 網路(柵格)和記憶體。
Myrinet2000 網路接口卡 (NIC) 可以使固件從運行中的主機上卸載協定。 固件直接與主機進程作用(OS 旁路),實現低時延通信功能,直接與網路作用,可傳送、接收並緩衝數據包。
組件及軟體
Myrinet提供兩個系列的組件:Myrinet2000和Myrinet10G。 對於集群系統來說,Myrinet2000是萬兆網路很好的替代品,但同時,Myrinet10G在性能和價格上相對於10G乙太網來說有很大的優勢。
