# Koji has two types of builders:
# 16Gb + 6 cores
# 128Gb + 48 cores
# There's no way to choose either, so we rely on luck
# This needs about 15 gigs per thread, otherwise OOMs. So, we calculate the number of threads we can afford to use for make:
# meminfo gives output in kB (1000 bytes)
%global numthreads %(echo $(( $(cat /proc/meminfo | grep MemTotal | awk '{print $2}') / 15000000 )) )
# But make sure it is > 0
%if 0%{numthreads} == 0
%global numthreads 1

# If _smp_build_ncpus is not defined (on older rpms)
# assume there's only one
%if 0%{?_smp_build_ncpus} == 0
%global _smp_build_ncpus 1

# Use the smaller number of threads
%if 0%{numthreads} > 0%{?_smp_build_ncpus}
%global numthreads %{?_smp_build_ncpus}

%global _description %{expand:
Graph-tool is an efficient Python module for manipulation and statistical
analysis of graphs (a.k.a. networks). Contrary to most other python modules
with similar functionality, the core data structures and algorithms are
implemented in C++, making extensive use of template metaprogramming, based
heavily on the Boost Graph Library. This confers it a level of performance that
is comparable (both in memory usage and computation time) to that of a pure
C/C++ library.
