The last decade has witnessed a rapid proliferation of superscalar cache-based microprocessors to build high-end computing (HEC) platforms. However, the growing gap between sustained and peak performance for full-scale scientific applications on conventional supercomputers has become major concern in high performance computing.
In this work we explore four applications from leading scientific domains in the areas of atmospheric modeling (FVCAM), magnetic fusion (GTC), plasma physics (LBMHD3D), and material science (PARATEC). We compare performance between vector-based architectures with leading commodity-based superscalar platforms.
Overall results show that the vector architectures attain unprecedented aggregate performance across our evaluated application suite, demonstrating the tremendous potential of modern parallel vector systems.
