Cray is a brand of Supercomputers with a 30 year history of innovation and leading edge performance. These computers are used to run demanding computational workloads, to solve massive calculations in science and engineering. A recent example is the Cray Jaguar (a specially built version of the XT4) used by scientists all around the world to solve world scale problems !

What we are attemping to do here is to provide a free resource for everybody who needs to know about past and present Cray computers or anything about the systems! if you have a question, please ask on the chat page!

Parallel Vector Processors, the core product line of Cray Research.

The XMP evolved from the Cray 1 and introduced dual processing to the Vector line. Originally limited to 16 MWd memory the later "Extended memory architecture" variants grew the address register from 24 to 32 bits growing the maximum program size to 2 GBytes. The XMP was brought to market whilst the Cray 2 was still in development and was a huge success that proved hard to repeat in later years. The line of big-iron vector super computers continued with the YMP, C90 and T90 each generation of which approximately doubled the CPU speed, number of CPUs, memory size and CPU quantity along with improving a host of other details.

30-06-09/Update 4 and looking for a new admin!

Hi Guys, I know we haven't updated this in a while and we really should do it more often but we are becoming exceedingly busy with exams, coursework and other projects. Do not fear that the wiki will not live on because I will keep it going as long as I can. Hosting costs money and I don't want to sound pushy but im afraid I have to be so I cannot stress enough HOW MUCH WE NEED YOUR SUPPORT. The Wiki will be updated again soon and the archive is due for a re design with more manuals and a better design. We are currently looking for knowledgable admins who are willing to maintain the wiki and add information handed to them too it so we may continue to work on the archive and on other projects. If you want to apply drop me an email at: adam@craywiki.co.uk with your name, your country, previous experience, where you gained your cray knowledge and what you think you can do for us. We would like experienced people but non-experienced people can also apply. Thankyou for your support, Adam Bradley (computid)
