Deep studying accelerators such as GPUs, FPGAs, and more not too long ago TPUs. Conceived by Harvard physics professor Howard Aiken, and designed and constructed by IBM, the Harvard Mark 1 is a room-sized, relay-based calculator. The machine had a fifty-foot long camshaft running the size of machine that synchronized the machine’s hundreds of element elements and used three,500 relays. The Mark 1 produced mathematical tables however was quickly outmoded by electronic stored-program computers.
