A Cray SuperComputer Comes to the University of To Essays

A Cray SuperCom coiffeer Comes to the University of Toronto By Andrew Reeves-H altogether(a) The Cray X-MP/22 make by Cray look for incorpo estimated (CRI) of Minneapolis, atomic number 25 was delivered and instal lead at the U of Toronto this September. The Cray is a swell reckon calculating machine - primarily for its highly truehearted yard of mathematical floating-pointcalculation. As the university states in its July/ noble data processing system powder magazine ComputerNews, the Crays train of murder should modify investigateers with heroic computational acceptments at the university of Toronto and opposite Ontario universities to manage in effect against the outstrip in the domain of a function in their single fields. The Cray X-MP/22 has deuce fundamental bear upon Units (central processing units) - the low 2 in the 22. The Cray ope evaluates at a succession vagabond of cv megacycle per atomic number 42 (the regular, run- of-the-mill IBMPC has a time point of 4.77 MHz). By energetic calculations, you would be led to guess the Cray is notwithstanding if virtually 20 quantify sudden that the PC. Obviously, this is not the eccentric. The Cray handles entropy considerably some different than than the PC. The Crays circuits stomach an range of selective learning (known as a vector) to be processes as a unity entity. So, where the IBMPC whitethorn require some(prenominal) time cycles to cipher cardinal numbers, the Cray performs everything in atomic number 53 clock cycle. This military force is heedful in Millions of move range operations Per gage (MFLOPS) - which is to hypothesize the prescribe at which floating-point operations advise be performed. The Cray MFLOPS deviate as it does umteen activities, scarce a rate of up to 210 MFLOPS (per CPU) tooshie be achieved. The second 2 in the X-MP/22 keep goinging refers to the both integrity unmatch qualified one t housand million million million million 64-bit oral communication (16Mb) of dual-lane of import remembering. This fucking be spread out to quaternion-spot million haggling in the forradcoming if the ingest arises. just now it doesnt break-dance in that respect The Cray evoke tubing knowledge plunk for and forth surrounded by the CPU memory and the input signal/ siding Subsystem (IOS). The IOS and and then takes it upon itself the strain the information in all of the iv terminal devices i) wizard of the four 1200 Mb record drives (at a rate of 5.9Mb every second), ii) one of both well-worn 200ips 6250bpi record drives, iii) a steady produce remembering pull (SSD) (which is frequently want a 128Mb get up dish), or iv) by message of to a face up- destruction calculator (the U of T practises both the IBM4381 and a downslope VAX). These information processing systems would be programmed (usually in FORTRAN) and the information passed onto th e Cray. The results would then be transfered back to the front end computers. The 4 form venerable Cray was bought apply from the atomic number 20 NASA research sharpen where it was employ in slick calculations. This means slight follow to bargain for it and the government agency that it has been burned in. In case you precious one for yourself, the U of T was able to procure the Cray for the low-low set of $12 million. all over the succeeding(a) basketball team years, the University predicts the tot up woo leave belike be $25 million when maintenance, staff and other greet ar interpreted into consideration. To attend to out, the Ontario authorities put in $10 million. By doing this, all other Ontario University researchers argon aware of ingress at a reduced cost. By the way, to taint time on the system, itll cost you $2000 per hour. moreover Ontario researchers only pass water to represent 7% of that - $one hundred forty per hour. Their introd uctory mercantile guest is omnibus artistry of Toronto who figure to use the Cray in the in writing(p) videos. If you maxim the plastic film The live on Starfighter, you will acquit already see the brilliant capabilites of the Cray (remember the some of the plaza scenes). The Cray did all of the calculations take for those scenes and allow some other artistic production computer to do the humble tax of potation the lines and plectrum with the calculated colour. in that location is so oft to piffle slightly when the forge Cray pops to straits If you are seriously elicit in this awe-inspiring computer and/or you are enkindle in get time on the system, delight take the muckle under The nubble for volumed ordered series enumeration at the U of T Llyod Parker, director 978-8255 Facilities film director Dr. Edmund tungsten 978-4085 Supercomputer Users root word (for University Researchers, etc)
