The choice of compiler can have a significant impact on both the performance and portability of scientific software. Modern HPC systems provide several compiler toolchains, each with different strengths, optimization capabilities, and supported libraries. This session introduces the main compilers available on CÉCI clusters and teaches how to build, optimize, and benchmark software...

26. Make/Cmake

Building scientific software often involves much more than invoking a compiler. As projects grow, managing dependencies, libraries, compilation options, and multiple source files can quickly become complex and error-prone. This session introduces modern build systems and teaches how to automate the compilation process using Make and CMake, from small personal projects to larger research...

27. Debuggin and profiling

Bernard Van Renterghem (UCL CISM)

Debugging and profiling are essential skills for developing reliable and efficient scientific software. While debugging helps identify and fix incorrect behavior, profiling helps understand where execution time and resources are spent. This session introduces practical tools and methodologies to diagnose problems, improve performance, and optimize applications running on HPC systems.
