Short(ish) lesson description
| 1. Introduction to Parallelism |
What is parallelisation and parallel programming?
How do MPI and OpenMP differ? Which parts of a program are amenable to parallelisation? How do we characterise the classes of problems to which parallelism can be applied? How should I approach parallelising my program? |
| 2. Introduction to the Message Passing Interface |
What is MPI?
How to run a code with MPI? |
| 3. Communicating Data in MPI | How do I exchange data between MPI ranks? |
| 4. Point-to-Point Communication | How do I send data between processes? |
| 5. Collective Communication | How do I get data to more than one rank? |
| 6. Non-blocking Communication |
What are the advantages of non-blocking communication?
How do I use non-blocking communication? |
| 7. Derived Data Types |
How do I use complex data structures in MPI?
What is contiguous memory, and why does it matter? |
| 8. Porting Serial Code to MPI |
What is the best way to write a parallel code?
How do I parallelise my existing serial code? |
| 9. Optimising MPI Applications | How can we understand how well our code performs as resources increase? |
| 10. Common Communication Patterns [Optional] | What are some common data communication patterns in MPI? |
| 11. Advanced Data Communication [Optional] |
How do I communicate structures?
How do I communicate non-contiguous data which isn’t easy to express as a derived data type? |
| 12. Survey | |
