6.7.30SHOW MPI VERSION

#Syntax

#Description

Show (i.e. get) the version of the MPI library used by HDFql. The information returned depends on the MPI library loaded by HDFql at runtime (which must be previously installed on the machine). If using an HDFql non MPI-based distribution, an error is raised. Please refer to https://www.mpich.org/static/docs/v3.4/www3/MPI_Get_library_version.html or https://www.open-mpi.org/doc/v3.1/man3/MPI_Get_library_version.3.php for additional information in case the MPI library used is MPICH or Open MPI, respectively.

#Parameter(s)

post_processing_option – optional option that transforms the result set according to the programmer’s needs, such as ordering or truncating (please refer to the section PROCESSING for additional information).

output_redirecting_option – optional option that specifies the cursor in use, an HDF5 object (i.e. dataset or attribute), a (text, binary, or Excel) file, or memory (i.e. user-defined variable) to write the result set into (please refer to the subsection INTO for additional information). If not specified, the cursor in use is populated with the result set instead (please refer to the chapter CURSOR for additional information).

#Return

The version of the MPI library used by HDFql as an HDFQL_VARCHAR.

#Example(s)

# show (i.e. get) version of the MPI library used by HDFql (e.g. if the MPI library used is Open MPI, it should return something similar to "Open MPI v3.1.6, package: Open MPI dummy@machine Distribution, ident: 3.1.6, repo rev: v3.1.6, Mar 18, 2020")
