• Debugging: slides used for an info session on debugging tools and techniques, as well as sample code.
• Fortran: sample Fortran code intended to illustrate Fortran 95, 2003, and 2008 features. This material is developed in preparation of a tutorial on modern Fortran features.
• HDF5: sample code showing how to read/write HDF5 files from C and Python. HDF5 can be used for parallel I/O, C sample code is provided. This material is part of a tutorial on HDF5.
• Java: sample code mostly for demonstration purposes.
• LinuxTools: some illustrations of using Linux tools such as the M4 macro processor, make files and autotools, as well as slides on version control using svn and git.
• Mpi: illustration of distributed programming using the Message Passing Interface API.
• NetCDF: sample code showing how to read/write NetCDF files for C, Fortran and Python. This material is prepared in preparation of extending the HDF5 tutorial to other data formats using in scientific computing.
• Optimization: illustrations of performance optimization opportunities.
• PBS: sample PBS torque batch scripts to illustrate features.
• Python: sample code to explore various Python features, standard library packages and third party libraries. Most of this material is used in a tutorial on using Python for scientific data processing.
• R: some very simple illustrations of how to run R scripts from the command line, and to submit as (PBS) jobs
• Sql: sample SQL that covers the basics of querying relational databases
• Visualization: data files, XDMF files and ParaView state files to use during a demo of scientific visualization with ParaView.
