Contained herein is a collection of material (source code, scripts, examples, etc...) to be used as examples for setting up user environments, running jobs, debugging and tuning applications, and related tasks for successful use of computational resources at the Argonne Leadership Computing Facility (ALCF).
Material here is typically developed for and used during ALCF training workshops, such as the ALCF Computational Performance Workshops typically held in the Spring and the ALCF Simulation, Data, and Learning Workshops in the Fall.
If not sure where to start, then a good place may be perusing ProgrammingModels for the resource of interest to gain experience compiling simple codes and submitting jobs.
- Applications: Example Makefiles, build scripts, etc... for some applications
- DataScience: Data & Learning examples with pointers to additional Tutorials
- Debug: Simple examples using available debugging tools
- Examples: Collection of examples demonstrating common tasks (e.g. compilation & setting affinity)
- Performance: Simple examples using availble performance tools
- ProgrammingModels: Simple examples using supported programming models
