IBM has "Vector" instructions, but the size of a vector is limited to one quadword. Usefull, but not what you normally think of as SIMD.

Most of my work is on Solaris and Linux servers and therefore I do not code in Assembler. However, I was active in porting a C library into classic z/OS.I was looking to do another port and stumbled upon the fact that that library has several SIMD architecture specific extensions (Altivec, Neon are two examples). While I can ignore that stuff, I became somewhat interested in the subject. Ze'ev Atlas
