Big data has revolutionized science and technology leading to the transformation of our
societies. High-performance computing (HPC) provides the necessary computational power …

The steadily increasing number of nodes in high-performance computing systems and the
technology and power constraints lead to sparse network topologies. Efficient mapping of …

Current generations of NUMA node clusters feature multicore or manycore processors.
Programming such architectures efficiently is a challenge because numerous hardware …

Due to the advent of modern hardware architectures of high-performance comput-ers, the
way the parallel applications are laid out is of paramount importance for performance. This …

We present a new method for mapping applications' MPI tasks to cores of a parallel
computer such that communication and execution time are reduced. We consider the case of …

A low-diameter, fast interconnection network is going to be a prerequisite for building
exascale machines. A two-level direct network has been proposed by several groups as a …

The placement of tasks in a parallel application on specific nodes of a supercomputer can
significantly impact performance. Traditionally, this task mapping has focused on reducing …

Abstract The Message‐passing Interface (MPI) standard provides basic means for
adaptations of the mapping of MPI process ranks to processing elements to better match the …

As the era of exascale supercomputing is coming, it is vital for next-generation
supercomputers to find appropriate applications with high social and economic benefit. In …
