# Built from the m9h/sodecl fork's opencl3-modernize branch, which brings sodecl
# up to the OpenCL 3.0 API, unbundles pybind11, and makes the installed package
# resolve its kernels + Random123 from %%{_datadir}/sodecl (upstream avramidis/sodecl
# hardcoded them relative to CWD and shipped no install rules for the Python module).

# Random123 headers (BSD-3-Clause) are shipped as OpenCL kernel include data.
%global _description %{expand:
SODECL is a library of ordinary differential equation (ODE) and stochastic
differential equation (SDE) solvers in OpenCL. It integrates many orbits of an
ODE/SDE system in parallel across the cores of a CPU or a GPU, which is useful
for example when fitting biological ODE models to data over large parameter
sweeps. The Euler, Runge-Kutta, implicit Euler/midpoint and Euler-Maruyama
schemes are implemented.}
