NVIDIA Course: CUDA and OpenACC Hands on Training

NVIDIA CUDA and OpenACC Hands on Training

This course is offered by NVIDIA by invitation. The course starts after the free NVIDIA seminar on Thursday 7th.

Dates:

• Thursday 7th June 2012 (from 2.30 pm to 5.30 pm)
• Friday 8th June 2012 (from 9.00 pm to 5.30 pm)

Agenda:

DAY ONE: (from 2.30 pm to 5.30 pm)

14:30-16:00 Introduction to CUDA programming model

• GPU architecture basics
• Simple CUDA program example
• Key principles
• Introduction to the concept of threads & blocks
• The memory hierarchy

16:00-16:15 Coffee Break

16:15-17:30 Hands-on on writing 2 simple applications with CUDA C (fill-in templates, with walkthrough in the end)

DAY TWO: (from 9.30 AM to 5.00/5.30 PM)

09:30-10:30  Porting applications for NVIDIA GPUs with OpenACC

• Introduction to CUDA and OpenACC directive approach
• OpenACC programming model, execution model, memory model
• The advantages of OpenACC in comparison with CUDA C/Fortran
• OpenACC directive syntax
• Main directives: parallel, kernels, loop, data and combinations; examples

10:30-10:45  Coffee Break

10:45-12:30  Porting applications for NVIDIA GPUs with OpenACC

• Other directives: host_data, cache, update, wait, declare; examples
• Runtime library routines
• Environment and conditional compilation
• Jacobi iterative method with OpenACC. Step-by-step optimization
• Example of using OpenACC in real applications: WRF numerical model
• Exercises with profiling and performance analysis
• Constraints
• Interoperability with CUDA libraries

12:30-13.30  Lunch Break

13:30-15:00  OpenACC hands-on

1) Compare OpenACC vs. CUDA C/Fortran:

• Implement the vector addition kernel in CUDA C or CUDA Fortran with the given template.

• Add OpenACC directives into existing serial implementation, build and execute the program (C directives).
• Compare the complexity and performance of two vector addition implementations above.
• Compare the CUDA Fortran Jacobi with OpenACC Jacobi implementation (Fortran directives).

2) OpenACC – step-by-step optimization study:

• Add proper directives
• Analyze compiler feedback
• Optimize for performance

15:00-15:15  Coffee Break

15:15-17:00  OpenACC hands-on (continued)
