parallel random-access machine definition
parallel (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.
