Thermal control is a key aspect of large-scale HPC centers, where a large number of computing elements is employed.

Abstract

Thermal control is a key aspect of large-scale HPC centers, where a large number of computing elements is employed. Temperature is directly related to both reliability, as excessing heating of components leads to a shorter lifespan and increased fault probability, and power efficiency, since a large fragment of power is used in the cooling system itself. In this paper, we introduce the TEXTAROSSA approach to ther mal control, which couples innovative two-phase cooling with multi-level thermal control strategies able to address thermal issues at system and node level.
