myrinet軟件簡介
Myri-10G Myri-10G 是 10 千兆位以太網與 HPC HPC 技術的集成體。 將 NIC 端口連接至 10 千兆位以太網交換機,即可實現高達每秒 9.8 千兆位的數據傳輸速度。 將 NIC 連接至一個 10G Myrinet 交換機,並提供一種網絡功能,支持相同的軟件接口,如以太網,以及用於套接字、MPI 和 DAPI 的低時延、內核旁路 API。 Myri-10G 能與 10 千兆位的以太網合用,以連接 IP 網絡(柵格)和內存。
myrinet組件及軟件
Myrinet提供兩個系列的組件:Myrinet2000和Myrinet10G。 對於集羣系統來説,Myrinet2000是萬兆網絡很好的替代品,但同時,Myrinet10G在性能和價格上相對於10G以太網來説有很大的優勢。
