FAQ: Tuning the run-time characteristics of MPI TCP communications
This FAQ is for Open MPI v4.x and earlier. If you are looking for documentation for Open MPI v5.x and later, please visit docs.open-mpi.org. Table of contents: How do I specify to use the IP network for MPI messages? But wait — I'm using a high-speed network. Do I have to disable the TCP BTL? How do I know what MCA parameters are available for tuning MPI performance? Does Open MPI use the IP loopb
Portable Hardware Locality (hwloc)
The Portable Hardware Locality (hwloc) software package provides a portable abstraction (across OS, versions, architectures, ...) of the hierarchical topology of modern architectures, including NUMA memory nodes (DRAM, HBM, non-volatile memory, CXL, etc.), sockets, shared caches, cores and simultaneous multithreading. It also gathers various system attributes such as cache and memory information a
