Numerical libraries

In this page will be stored exercises about the most used numerical libraries for HPC, such as FFTW, linear algebra libraries and PETSc .

Each exercise is described in the text section and solved in the solution section. We recommend you to study carefully the text of the proposed problem, write your own solution, and then compare it with the solution we propose in the solution section. Solutions of the exercises are provided in both C and FORTRAN languages.
