	\begin{tcolorbox}[title=Context]
		Heterogeneous datacenter architectures are common~\cite{DBLP:conf/date/MilojicicFDR21} due to the end of Dennard's scaling.
		Nowadays, computational needs of AI drive managers to diversify datacenters even more~\cite{DBLP:journals/computer/AthavaleBBMMPS24}.
		In result datacenters become extremely complex and hard to operate.
