Abstract: Delivering high performance in an energy-efficient manner is of great importance in conducting research in computational sciences and in daily use of technology.
From a computing perspective, a novel concept (the HAEC Box) has been proposed that utilizes innovative ideas of optical and wireless chip-to-chip communication to allow a new level of runtime adaptivity for future computers, which is required to achieve high performance and energy efficiency.
HAEC-SIM is an integrated simulation environment designed for the study of the performance and energy costs of the HAEC Box running communication-intensive applications.
In this work, we conduct a verification of the implementation of three resilient communication models in HAEC-SIM.
The verification involves two NAS Parallel Benchmarks and their simulated execution on a 3D torus system with 16x16x16 nodes with Infiniband links.
The simulation results are consistent with those of an independent implementation.
Thus, the HAEC-SIM based simulations are accurate in this regard.
