Shared rapid file system on Ethernet for HPC: central file server demonstration

We are going to demonstrate two functionalities about the shared rapid file system on Ethernet. One is throughput and the other is "user ID mapping ". Shared rapid file system was originally implemented on our HPC system named numerical simulator 111 that has crossbar interconnection network. During this demonstration, we would like to discuss about a file server allocation concept, namely what is the difference between "central file system " and "distributed file system", and what kind of application and HPC system fit these file systems and so on.
