pympistandard 0.2.0

Python API to the MPI Standard.

pympistandard

This library provides programmatic access to the extracted data from the MPI Standard build process. The library comes packaged with the dataset for the latest MPI Standard version. It is possible to override the database loaded with either an environment variable or passing of a path:

export "MPISTANDARD"="/my/path/to/my/apis.json"

import pympistandard as std
std.use_api_version(1, given_path="this_is_definitely_a_path")

import pympistandard as std
std.use_api_version(1, force_bundled=True)

---

Usage example:

import pympistandard as std
std.use_api_version(1)

if "mpi_send" in std.PROCEDURES:
    mpi_send = std.PROCEDURES.mpi_send 
    mpi_send = std.PROCEDURES["mpi_send"]

print(mpi_send.express.iso_c)
# int MPI_Send(const void* buf, int count, MPI_Datatype datatype, int dest, int tag, MPI_Comm comm)

embiggened = [proc.name for proc in std.PROCEDURES.values() if proc.has_embiggenment()]
print(f"Embiggened procedures in 4.1: {len(embiggened)}")
# 154

This module will run with core Python 3.7. If you are using an older version of Python, you can install additional PyPi packages to support the requirements of this module. This has been tested with Python 3.6:

virtualenv -m venv
source venv/bin/activate
pip install dataclasses importlib_resources
