The code base for OpenMPI was completely new, but it brought in ideas and techniques from all the different teams. Currently, the two major open-source MPI implementation code-bases are OpenMPI andMPICH2. 而MPICH2是MPICH的一个版本。有的计算机厂商,也会针对旗下机型特点,自主开发基于MPICH的MPI...
Comment: I'm building a package depending on openmpi. I pinned the run dependency version to 4.1.6 (which is on conda-forge). However when installing the package it sometimes resolve to the external build. As a consequence when I install...
