Development of a Normal Modes Analysis element for SAMSON platform

Participants : Yassine Naimi, Alexandre Hoffmann, Sergei Grudinin, Stephane Redon.

We are currently developing an element for the SAMSON platform for the calculation of normal modes based on the Normal Modes Analysis method. This element will be based on the program developed by Alexandre Hoffmann and Sergei Grudinin on Linux and Mac operating systems. First, we have ported the initial program from Linux and Mac operating systems to Windows and linked the program to the libraries needed for the calculations. These libraries consist in: an optimized version of BLAS (Basic Linear Algebra Subprograms) library called OpenBLAS for basic vector and matrix operations; LAPACK (Linear Algebra PACKage) library for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems; ARPACK library for solving large scale eigenvalue problems and ARMADILLO library which is a linear algebra library for the C++ language. We will also compare the performances of our program using these libraries to the Intel MKL (Math Kernel Library) libraries. The ultimate goal is to develop the interface for the SAMSON platform using the SAMSON SDK and Qt software.
