Rompio is a software that evaluates the performance of MPI collective, independent, asynchonous, and POSIX file I/O operations.
Users can choose between two file layouts, namely N processors to N files and N processors to one file, which ensures the flexibility that users need when conducting performance measurements. The write access patterns available in Rompio include both non-strided and strided options, further adding to the tool's versatility.
In addition, Rompio also enables users to obtain measures of pure network performance for related MPI collective calls. With a comprehensive README file available, users can quickly gain insights into how to use Rompio, as well as an in-depth understanding of the output data produced by the application.
Overall, users can rest assured that they will receive accurate and helpful data when using Rompio to measure MPI collective, independent, asynchronous, and POSIX file I/O performance. With its many features and options, this software is ideal for individuals seeking to gain deeper insight into file system utilization within the LANL ASC computing environment.
