| On Caviness and DARWIN we would likely choose the Intel Python distribution selection a Python 3 version over Anaconda (e.g. ''vpkg_versions intel-python'') since it automatically enables Intel's distribution channel. That channel includes Numpy built against the Intel MKL library, for example, and other highly-optimized variants of computationally-intensive Python components. | On Caviness and DARWIN we would likely choose the Intel distribution selecting a Python 3 version over Anaconda (e.g. ''vpkg_versions intel-oneapi'' or ''intel-python'') since it automatically enables Intel's distribution channel.

| As of November 2020, the majority of packages populating the Intel channel require baseline operating system libraries (like ''glibc'') newer than what Farber provides: a clear example of the binary compatibility issues that are present in conda software distribution. | As of November 2020, the majority of packages populating the Intel channel require baseline operating system libraries (like ''glibc'') newer than what Farber provides: a clear example of the binary compatibility issues that are present in conda software distribution. |

| The ''--no-binary :all:'' flag prohibits the installation of any packages that include binary components, effectively forcing a rebuild of mpi4py from source. The ''--compile'' flag pre-processes all Python scripts in the mpi4py package (versus allowing them to be processed and cached later). The environment now includes support for mpi4py linked against the ''openmpi/4.0.2'' library on Caviness: | The ''--no-binary :all:'' flag prohibits the installation of any packages that include binary components, effectively forcing a rebuild of mpi4py from source.
