It can be used like the network file system (NFS) and has solved the problem of data coherency in the high-speed transmission of data in a broadband environment, which the NFS has not. Moreover, adjustment of the TCP/IP parameter in the OS to improve speed is unnecessary, and special hardware is not needed, unlike with the SAN construction by iFCP etc., so the cost of introduction can be held down. In this report, we measured the file IO performance of SRFS on Ether on the Internet (ITBL network) between JAXA (Chofu)-NIED (Tsukuba). In this test, performance reached 220-270 [Mbps] (180-200 [Mbps] with a VPN connection) in SRFS on Ether, in contrast with the limit of 10-20 [Mbps] encountered with the NFS. Thus it is possible to use the HPC system from a remote location because SRFS on Ether has demonstrated sufficiently high performance in a practical environment like the ITBL network.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
