OPIOM:基于Myrinet的脱机I/O

Offline I/O Based on Myrinet:OPIOM

随着硬件技术和网络技术的发展 ,在簇计算系统中出现了存储子系统和计算、网络通讯子系统性能不匹配的问题。文中提出的设计以最小代价将通讯网络和存储网络结合起来。这一设计在Myrinet上通过脱机I O实现 :在将数据传递到远端节点以前 ,先将从SCSI磁盘异步读出送入Myrinet接口的嵌入式存储器 。

As the progress of hardware and network, the performance of storage sub-system dosent match the computing and communication section. OPIOM, a new design to merge the communication network and the storage network at the best price is proposed. OPIOM with the Myrinet interconnect: OPIOM moves data asynchronously from SCSI disks to the embedded memory of a Myrinet interface in order to send it to a remote node. The experiments show its high performance and extremely low cost.
