 Compared to PGAS frameworks (e.g., MPI), experimentation over a subset of \textit{NAS Parallel Benchmarks} shows that MENPS can obtain comparable speedup in some of the computation tasks, while achieving much better productivity due to DSM's support for transparent caching, etc. \cite{Endo_Sato_Taura.MENPS_DSM.2020}. These results back up their claim that DSM systems are at least as viable as traditional PGAS/message-passing frameworks for scientific computing, also corroborated by the resurgence of DSM studies later on\cite{Masouros_etal.Adrias.2023}.
 
-\section{PGAS and Message Passing}
+\section{Alternatives to DSM}
 While the feasibility of transparent DSM systems over multiple machines on the network has been made apparent since the 1980s, predominant approaches to ``scaling-out'' programs over the network relies on the message-passing approach \cite{AST_Steen.Distributed_Systems-3ed.2017}. The reasons are twofold:
