Publikováno v: EPJ Web of Conferences, Vol 247, p 04020 (2021)

The calculation of macroscopic neutron cross-sections is a fundamental part of the continuous-energy Monte Carlo (MC) neutron transport algorithm. MC simulations of full nuclear reactor cores are computationally expensive, making high-accuracy simula

Publikováno v: MCHPC@SC

The memory topology of high-performance com- puting platforms is becoming more complex. Future exascale platforms in particular are expected to feature multiple types of memory technologies, and multiple accelerator devices per compute node. In this

Publikováno v: IPDPS

Electrical power has become an important design constraint in high-performance computing (HPC) systems. On future HPC machines, power is likely to be a budgeted resource and thus managed dynamically. Power management software needs to reliably measur
