The RISC-V Vector ISA is credited to Cray "vector processors" [1], explicitly by the RISC-V authors.

Additionally, I believe experimenting with vector ISAs was mentioned as one of the reasons they started another RISC research project, which ended up being RISC-V.

Yeah, RISC should have been called CISC, Cray Instruction Set Computer.

Well it is the fifth RISC ISA from the people who invented RISC.
