part of the issue is the MVS evolved from a paradigm where people submitted card decks and the actual execution occured at much later period ... with at most an operator present ... the responsible person was no where around. the unix & desktop platforms evolved from the exact opposite paradigm ... the computer was directly interacting with the person executing the application. those platforms have had to do quite a bit of evolution to handle server&unattended operation. however, there has some interesting evolution on their server side ... the megadatacenters with hundreds of thousands of blades (and millions of processors) with provisioning for on-demand use is quite remarkable ... I doubt if anybody is claiming current mainframe operating systems are prepared to run several hundred thousand blades in a megadatacenter ... including allowing an entity to do on-demand, dynamically provision 17,000 cores for 240TFLOPs (for a "batch" supercomputer) @ $1,2479/hr. recent posts mentioning somebody doing just that with Amazon cloud: http://www.garlic.com/~lynn/2012.html#78 Has anyone successfully migrated off mainframes? http://www.garlic.com/~lynn/2012.html#80 Article on IBM's z196 Mainframe Architecture http://www.garlic.com/~lynn/2012.html#82 Has anyone successfully migrated off mainframes? http://www.garlic.com/~lynn/2012b.html#28 New IBM mainframe instructions http://www.garlic.com/~lynn/2012b.html#30 New IBM mainframe instructions for one thing, a single mega-datacenter is estimated to be more processing power than the aggregate of all mainframes in the world today. This article from last year http://news.cnet.com/8301-13846_3-57349321-62/amazon-takes-supercomputing-to-the-cloud/ The dynamic, on-demand amazon cloud "supercomputer" is compared to the Fujitsu K Computer ... that operates at 10 petaflops (10,000tflops), has 864 racks, 88,128 interconnected processors and estimated total provisioned cost of $20M (less than maxed out 80 processor z196 @ $28M, rated at 50BIPS); $23,148/rack, $227/processor, $2000/TFLOP, $2/BFLOP, 113BFLOP/processor, 11,576TFLOP/rack ... 102processors/rack By comparison, 80 processor z196 @28M and 50BIPS works out to $350,000/processor, $560,000/BIPS, and 624MIPS/processor. more recent article about on-demand, dynamic, amazon supercomputer http://arstechnica.com/business/2012/04/4829-per-hour-supercomputer-built-on-amazon-cloud-to-fuel-cancer-research/ from above: It ran for three hours on the night of March 30, at a cost of $4,828.85 per hour. Getting up to 51,132 cores required spinning up 6,742 Amazon EC2 instances running CentOS Linux. This virtual supercomputer spanned the globe, tapping data centers in four continents and every available Amazon region, from Tokyo, Singapore, and Sao Paolo, to Ireland, Virginia, Oregon, and California. As impressive as it sounds, such a cluster can be spun up by anyone with the proper expertise, without talking to a single employee of Amazon. ... snip ... Not sure what an EC2 instance is made of for this (&/or if they are all the same), an e5-2600 would have 16 cores and 6742 instances would be aggregate of 107,872 cores (aka processors). past posts in thread: http://www.garlic.com/~lynn/2012l.html#16 X86 server http://www.garlic.com/~lynn/2012l.html#18 X86 server http://www.garlic.com/~lynn/2012l.html#19 X86 server http://www.garlic.com/~lynn/2012l.html#20 X86 server http://www.garlic.com/~lynn/2012l.html#25 X86 server http://www.garlic.com/~lynn/2012l.html#28 X86 server http://www.garlic.com/~lynn/2012l.html#29 X86 server http://www.garlic.com/~lynn/2012l.html#30 X86 server http://www.garlic.com/~lynn/2012l.html#31 X86 server -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
