Started in the 1950s. The first successful mainframe computer is invented by IBM.
Started in 1960s. Seymour Cray invent the Supercomputer.
Perform tasks on huge amounts of external data. Run multiple programs concurrently.
Focused on speed and accelerated performance. Much processing power than mainframes. They are often a cluster or grid of smaller computers working together on whatever problem they are looking to solve.
Handle mission-critical business workloads. Example: updates a database system for inventory control (goods), airline reservations (services), or banking (debit and credit cards processing)
Supercomputers designed for academic or research purposes, rather than for hosting workloads that you’d find in a typical business. Super computers are used for large and complex mathematical computations. Example: forecasting weather and quantum physics.
Size of a refrigerator, Mainframe computers smaller than supercomputer in size.
Supercomputers are the largest computers.
Mainframe computers are less costly than supercomputers.
Supercomputers are the most costly in the worlds.
Run many different kinds of operating systems (z/OS, Linux, etc.).
Typically run a variant of Linux as their operating system.
Support many concurrent users
Usually do not support many concurrent users.
Have performance measured in Millions of Instructions per Second (MIPS)
Have performance measured in Floating Point Operations per Second (FLOPS)
IBM with Z Systems (leader), Unisys with ClearPath Libra, Hitachi co-developed the zSeries z900 with IBM, Fujitsu (formerly Siemens)with BS2000, and Fujitsu-ICL VME.
IBM Summit (2018), Sunway TaihuLigh (2016), Cray Titan (2012), IBM Roadrunner (2008) and Fujitsu K computer (2011)
