Is it farther or further?
(PRAM) An idealised parallel processor consisting of P processors, unbounded shared memory, and a common clock. Each processor is a random-access machine (RAM) consisting of R registers, a program counter, and a read-only signature register. Each RAM has an identical program, but the RAMs can branch to different parts of the program. The RAMs execute the program synchronously one instruction in one clock cycle.
