The Sunway series microprocessors were developed mainly for the use of the military of the People's Republic of
China. It is expressed on online forums that the original
microarchitecture is believed to be inspired by the
DEC Alpha.[2][better source needed] The SW-3 is thought especially to be based on the
Alpha 21164.[3]
Jack Dongarra states about the follow-on
SW26010, the "ShenWei-64 Instruction Set (this is NOT related to the DEC Alpha
instruction set)", and doesn't say it's a new instruction set from the three prior generations he names;[4][5] although precise details of the instruction set are unknown.
Manycore architecture, with 4 CPU clusters on a chip, each comprising 64 lightweight compute CPUs with an additional management CPU, linked by a
network-on-a-chip[7]
