IMB-IO Blocking Benchmarks
This section describes blocking I/O benchmarks. The benchmarks can run with varying transfer sizes X, in bytes. The timings are averaged over multiple samples. The basic MPI data type for all data buffers is MPI_BYTE. In the definitions below, a single sample with a fixed I/O size X is used.
Every benchmark contains an elementary I/O action, denoting a pure read or write. Thus, all benchmark flavors have a Write and a Read component. The [ACTION] placeholder denotes a Read or a Write alternatively.
The Write flavors of benchmarks include a file synchronization with different placements for aggregate and non-aggregate modes.
