LNCC SDumont supercomputer upgrade

The National Scientific Computing Laboratory (LNCC) and Eviden/Atos signed a new contract worth us$ 19.4 million, which will allow the machine to go from the current 5.1 Petaflop/s to 17 Petaflop/s of capacity. The technology will be based on the BullSequana XH3000 architecture, and with the expansion it will be the most powerful supercomputer in Latin America dedicated to academic studies.

Parallel Spectral Numerical Methods

Very nice Wikibook based on Parallel Spectral Numerical Methods by Chen et al. (2012) from University of Michigan. Discusses how to solve ordinary differential equations (ODE) and partial differential equations (PDE) using separation of variables. Next, it introduces numerical time-stepping schemes that can be used to solve ODEs and PDEs. This is followed by an introduction to pseudo spectral methods through an overview of the discrete Fourier Transform (DFT) and the Fast Fourier Transform (FFT) algorithm that is used to quickly calculate the DFT. Finally it will combine all of these to solve a couple of different PDEs first in a serial setting and then in a parallel setting. The programs will use Matlab and Fortran. A Python implementation of some of the Matlab programs is also provided.

WSCAD and SBAC-PAD

The Symposium on High Performance Computing Systems (WSCAD), a national event organized by the Brazilian Computing Society (SBC) and the Institute of Electrical and Electronic Engineers (IEEE), aims to highlight the main developments, applications and trends in Computer Science. Computing for distributed systems, high-performance processing and architecture. The IEEE International Symposium on Computer Architecture and High Performance Computing (SBAC-PAD) is usually held annually in conjunction with the WSCAD event in October.
