Successes and frustrations in the solution of large electromagnetic problems in supercomputers

The solution of very large electromagnetic problems might be obtained using large computer facilities as singular High Performance Computers or Supercomputers. In these solutions, suitable numerical methods for large structures should be used, as fast methods e.g. Multilevel Fast Multipole Algorithms. The implementation of this kind of methods in a Computer capable to deal with the large amount of data and calculations is not simple; depending on the nature of the computer (shared memory based, distributed memory based, multi-core, many-core, etc.) you can obtain different performances, you can solve different applications, you must adapt the method to the machine-type, or you should reconsider the implementation strategies to achieve success when you lead with bigdata issues.
