This repository aims to guide user through using the CLAW Language directive as well as the CLAW Compiler to transform their Fortran code.

Original code is here

1. Merge all the 4 loops together to form only a single loop. [solution] [transformed]
2. Merge the two first loops together and the two last ones together. [solution] [transformed]

clawfc -o transformed_code.f90 code.f90

Original code is here

1. Reorder loop i with j [solution] [transformed]

clawfc -o transformed_code.f90 code.f90

If you are still willing to learn about the CLAW Compiler and you want to implement your own transformation then you should keep going with this exercise section.
