High-performance computing (HPC) has become an essential tool in both scientific and industrial communities because it provides an excellent environment for solving a wide range of problems in modern science and engineering. Nowadays, HPC clusters (HPCC) are, in fact, the main architecture for supercomputers due to the high performance of commodity microprocessors and networks and to the lower price/performance ratio. Moreover, current standalone computers present tremendous power and they could be considered as desktop HPC platforms if their resources are appropriately exploited. Today’s HPC platforms are based on clusters of multicore nodes, which include accelerator devices such as GPUs or Xeon Phi coprocessors. Hence, the heterogeneity characterizes modern HPC platforms. Recent technological advances had a strong impact in the computational power of a wide range of platforms. Recently, HPC has become even more popular due to the rise of computational resources into devices as extended as smartphones, tablets, laptop and stand-alone computers, since all of them are based on multicore processors which can include coprocessors devices. This special issue is devoted to HPC focusing on twofold: the rise of computationally demanding scientific models of practical interest and the evolution of HPC technology, which can meet these high-performance requirements in a wide diversity of scenarios.
