NASA Shuts Down It’s Last Mainframe:
“This month marks the end of an era in NASA computing. Marshall Space Flight Center powered down NASA’s last mainframe, the IBM Z9 Mainframe,” Cureton said…
Cureton, who once programmed a System 360 mainframe in assembly language at the Goddard Space Flight Center, came to their defense:
“They’re really not so bad honestly, and they have their place. Things like virtual machines, hypervisors, thin clients, and swapping are all old hat to the mainframe generation though they are new to the current generation of cyber youths…
Today, they are the size of a refrigerator but in the old days, they were the size of a Cape Cod. Even though NASA has shut down its last one, there is still a requirement for mainframe capability in many other organizations.”
More than four decades ago, when NASA acquired two “super-speed” System 360 Model 95 machines in 1968, IBM touted the machines’ mathematical abilities. “Both of NASA’s Model 95s are handling space exploration problems which require unusually high computation speeds,” IBM said. “The Model 95s are capable of computing 14-digit multiplications at a rate of over 330 million in a minute.”
Nowadays, the fastest supercomputer performs 10.5 quadrillion calculations per second.
The IBM system also had a staggeringly large amount of memory — 4MB of main memory supplemented by 1MB of “ultra-high-speed thin-film memories.”
