Dear All, I sincerely apologize for the late notification. Last week, we have studied about 'another layer' for non-POSIX APIs, benchmarks (YSCB, IOR), some papers supporting application level mapping scheme for the servers based on key/value store, and papers related with PFS (PVFS,PLFS). Also we are still concerned about the client FS design for supporting non POSIX.

Dear All, In the last week, we analyzed all experimental results of our load balancing algorithms and comparison algorithms. In this week, we plan to think a new strategy dynamically choose data replicas to send requests to, in order to guarantee a low response latency. Best Regards!
