Why scripting ?

• Sourcery VSIPL++ is designed with productivity in mind:

• Compact and intuitive syntax

• Yet:

• Algorithms developed in a High Productivity

Environment (Matlab, Python)

• Rewritten in C++

• How can this workflow be improved ?

Development Workflow

Algorithms are written (and tested !) twice, using different languages, different tools,in differing environments.

Integrated Workflow

Hybrid programmingScripting (Matlab, Python, etc.)

C++

• Seamless integration of prototyping and optimization• Code generation• Profiling• Validation

• Support data-flow in both directions• Simpler workflow -> Higher Productivity

We would like your feedback !
