For those of us not in the know, from whom were they borrowed?

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.

This PDF might help, it explains the differences with other ISAs
