"""Charm4py (Charm++ for Python) is a distributed computing and parallel
programming framework for Python, for the productive development of fast,
parallel and scalable applications. It is built on top of Charm++, a C++
adaptive runtime system that has seen extensive use in the scientific and
high-performance computing (HPC) communities across many disciplines, and
has been used to develop applications that run on a wide range of devices:
from small multi-core devices up to the largest supercomputers."""

# setup.py builds its own charm++, but libcharm.so

# when setup.py tries to load it to get version. We need to explicitly
# link libcudart when building the charm++ library.
# To do this, the following patch:
# 1) hacks setup.py to apply a patch to the charm++ Makefile
# causing the Makefile to include libcudart when building libcharm.so
# 2) inserts the patchfile needed to do so.
# This is convoluted, but best way I see since setup.py untars the
# charm++ sources and we need to patch a file that is in the tarball.
#
# The patch to the Makefile adds SPACK_CHARM4PY_EXTRALIBS to the link
# arguments. This needs to be set in the environment to be effective.
