in one clock cycle. This power is measured in
Millions of Floating Point Operations Per Second (MFLOPS) - which is to
say the rate at which floating-point operations can be performed. The Cray
MFLOPS vary as it does many activities, but a rate of up to 210 MFLOPS
(per CPU) can be achieved.

The second '2' in the X-MP/22 title refers to the two million 64-bit
words (16Mb) of shared central memory. This can be expanded to four
million words in the future if the need arises. But it doesn't stop there!
The Cray can pipe information back and forth between the CPU memory and
the Input/Output Subsystem (IOS). The IOS then takes it upon itself the
store the information in any of the four storage devices: i) one of the
four 1200 Mb disk drives (at a rate of 5.9Mb every second), ii) one of two
standard 200ips 6250bpi tape drives, iii) a Solid State Storage Device
(SSD) (which is much like a 128Mb RAM Disk!), or iv) through to a front-
end computer (the U of T uses both the IBM4381 and a ...
