\glsentrylong{hbm} is a novel memory technology promising an increase in peak bandwidth. It is composed of stacked DRAM dies \cite[p. 1]{hbm-arch-paper} and is slowly being integrated into server processors, notably the Intel® Xeon® Max Series \cite{intel:xeonmaxbrief}. \gls{hbm}on these systems may be configured in different memory modes, most notably, HBM Flat Mode and HBM Cache Mode \cite{intel:xeonmaxbrief}. The former gives applications direct control, requiring code changes while the latter utilizes the \gls{hbm} as cache for the systems DDR based main memory \cite{intel:xeonmaxbrief}. \par
