BMI: a network abstraction layer for parallel I/O

摘要: As high-performance computing increases in popularity and performance, the demand for similarly capable input output systems rises. Parallel I/O takes advantage of many data server machines to provide linearly scaling performance parallel applications that access storage over system area network. The demands placed on network by a are considerably different than those imposed message-passing algorithms or data-center operations; and, there popular varied networks use modern machines. These considerations lead us develop abstraction layer which is efficient thread-safe, provides operations specifically required processing, supports multiple networks. buffered message interface (BMI) has low processor overhead, minimal impact latency, can improve throughput file workloads as much 40% compared other more generic abstractions.
