    • Developed at CCS for the TMC CM-5 by
      Bill Carlson and Jesse Draper
    • Parallel extension to GNU C and C++
      compilers
    • It introduced the "aux" type to get
      at the vector registers in the CM-5
    • Ported to SGI T3D and T3E and is used
      to take advantage of distributed shared memory using the "dist" type
    • Can use asm statement
