随着集群系统中节点数量的不断增长，在此类系统的各个方面利用可扩展算法成为维持性能的关键。虽然可扩展算法已成功应用于并行 I/O 的某些领域，但许多操作仍然以不协调的方式执行。在这项工作中，我们考虑在三种文件系统场景中将可扩展算法应用于构成 MPI-IO 接口的许多操作的可能性。从这次评估中，我们提取了一组文件系统特征，有助于开发可扩展的 MPI-IO 实现。
As the number of nodes in cluster systems continues to grow, leveraging scalable algorithms in all aspects of such systems becomes key to maintaining performance. While scalable algorithms have been applied successfully in some areas of parallel I/O, many operations are still performed in an uncoordinated manner. In this work we consider, in three file system scenarios, the possibilities for applying scalable algorithms to the many operations that make up the MPI-IO interface. From this evaluation we extract a set of file system characteristics that aid in developing scalable MPI-IO implementations.
