The 1^st talk : Developing simulation codes on super-computer

7 / 1 / 2015 (wednesday) 1:30 – 2:15 pm

PMI seminar room (2-404)

Numerical simulation is an essential tool to research on various areas. To develop simulation codes, developers consider the model which may be presented by partial differential equations (PDE), its discretizations, and solution methods of resulting systems. In this talk, I will consider the numerical methods for PDE based simulation which are developing and include discretization methods and linear and nonlinear solvers. I will focus on what have to be considered to develop simulation codes on modern high performance computers (super-computer, HPC). Also, I will consider multigrid and domain decomposition methods which are solvers to fit modern HPC.

The 2^nd talk : Modern super-computer, Optimization, and HLST

7 / 1 / 2015 (wednesday) 2:30 pm – 3:15 pm

PMI seminar room ( 2-404 )

Optimization the code is an essential part of developing simulation code and related to computer architectures. Current and future computer architectures are multi-core, multi-node, and heterogeneous and code developers have to aware them to develop relevant simulation codes. Due to complexity of the high performance computer (HPC), collaboration of applicationist, mathematician, and computer scientist is essentially needed. In this talk, I will consider architecture of the modern HPC, parallelizations, and optimization issues. As an example of collaboration, I will introduce the HLST team in EUROfusion and their efforts in developing simulation codes for fusion energy

Snack will be provided between seminars
