Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Random Grid Engine tips and tricks

The following work with Son of Grid Engine (SGE) 8.1.9 as configured on the University of Sheffield's ShARC and Iceberg clusters.

Jobs with dependancies

You can use the -hold_jid <<job-name or job-name>> option to make jobs run only when other jobs have finished, rather than having jobs start and sit waiting for other tasks to complete.

In this article, I will share some of my experience on installing NVIDIA driver and CUDA on Linux OS. Here I mainly use Ubuntu as example. Comments for CentOS/Fedora are also provided as much as I can.

	# Build a Python extension module using pybind11
	# pybindings_add_module(<module>)
	# Here <module> should be the fully qualified name for the module,
	# e.g. pybindings_add_module(foo.bar._baz)
	# <module> becomes the target name in case you wish to do something to it later
	# The source for the binding must be placed in src/pybindings/{relpath}/py{name}.cc

	function(pybindings_add_module module)
	set(target_name ${module})
	string(REPLACE "." "/" modpath ${module})
