@ Tom 64
I did that 15 years ago when AMD's Opteron was the best server chip by miles, so I bought AMD and sold Intel. AMD stock went down and Intel's went up. 2 -3 years later when the first P3 Xeons came out and delivered better Price/performance that Opteron the stocks reversed and I lost again.
Either Wall Street knows nothing or they know everything, they just tell you or I, ever.
@ David Lester.
"Historically, since custom Mainframes died, that's always meant using Intel processors."
No quite right. Contemporary with mainframes we had bespoke supers from Cray, CDC, NEC and IBM SP2/3. Post those we had oddities like Thinking Machines, ELIXI and then the first ccNUMA super from Convex, which you can still today as an HP something or other. Then just before we got to Intel based clusters, we had DEC Alpha as the main HPC cluster processor of choice. Once Intel developed the PentiumPRO there was only going to be one $/flop winner and that was x86.
On the stock component side, you can't use Ethernet, due to latency and so the cost is in the interconnect, such as Infiniband, (which is by far the biggest). Earlier high speed low latency interconnects included, SCI and Myrinet.
@AC I'm sure plasma physics, (weapons simulation), is a hug e part of most HPC. Most in the UK would be done at AWE on there own cluster and shared memory systems. It's the same in France, (can't remember the facility, but it's off the perpiherique, not far from Orly). Most HPC, (particle physics and bioinformatics are not in my view HPC, but are instead massively parallel), clusters are used for CFD, (e.g. everything we make either holds a gas or liquid or has a gas or liquid moving over it or through it), and various computational chemistry problems, such as density functional theory.
No, but you see people from Glasgow and Bouremouth buying their petrol locally when it's produced in Pembrokeshire or Merseyside. Your green beans, usually come from Egypt, Spain, Peru or central america, where is the sense in that from your logic? Oh and when we leave those said beans will be CHEAPER to buy as not covered by the CAP, which fucks over third world producers for EU farmers, nice!
Hugo, they owned Xenix, which was a early Lunix port. From memory they never implemented record locking, so it didn't attract that many customers. Nortel in Hemel Hempstead (Northern Telecom in those days) built a 16bit (can't remember the name of Intel's 16bit bus architecture that competed with VersaBus and VME), Xenix system in the early 80s. 16MHz 8086 CPU I seam to recall.
I think your £5 per server chip is out by a couple of orders of magnitude. For something that competes on power/watt with Intel, they cab charge £500 and be very very competitive with Xeon. Two problems remain however, a) how much does the server motherboard cost and b) where are the applications outside of webservers?
