Vector Engine (VE) is a family of vector processors designed as PCIe accelerator cards designed by NEC.

Overview[edit]

NEC introduced the Vector Engine (VE) in 2017 as the successor to the SX line of supercomputers. VEs depart from all prior generations by departing from the traditional self-hosted vector processor and nodes. With the introduction of the Vector Engine, NEC moved to an accelerator card architecture whereby a Vector Engine (VE) PCIe card are installed onto standard x86 server which serves as the Vector Host (VH).

Vector Engine Type 10 (VE10) are first-generation Vector Engines. Those processors are based on the SX-Aurora microarchitecture and are fabricated on TSMC 16 nm process. Type 10 features eight vector cores along with six HBM2 stacks.
