+3-Node ARM Altra (3n-alt)
+---------------------------
+
+One 3n-tsh testbed is built with: i) one SuperMicro SYS-740GP-TNRT
+server acting as TG and equipped with two Intel Xeon Icelake Platinum
+8358 processors (80 MB Cache, 2.60 GHz, 32 cores), and ii) one Ampere
+Altra server acting as SUT and equipped with two Q80-30 processors
+(80* ARM Neoverse N1). 3n-alt physical topology is shown below.
