The MPI This lets you quickly deliver maximum application performance even if you change or upgrade to new interconnects without requiring major modifications to the software or operating systems. The library provides an accelerated, universal, multifabric layer for fast interconnects via OFI, including for these configurations:. It accomplishes this by dynamically establishing the connection only when needed, which reduces the memory footprint.

It also automatically chooses the fastest transport available. An application binary interface ABI is the low-level nexus between two program modules. It determines how functions are called and also the size, layout, and alignment of data types.

With ABI compatibility, applications conform to the same set of runtime naming conventions. So even if you and not ready to move to the new 3. Run all of the supported benchmarks or specify a single executable file in the command line to get results for a particular subset. User Guide. The library has a robust set of default parameters that you can use as is, or refine them to ensure the highest performance.

If you want to tune parameters beyond the defaults, use mpitune to adjust your cluster or application parameters, and then iteratively adjust and fine-tune the parameters until you achieve the best performance. View All Documentation. Runtime Version.
