1000core Processor isnt as impressive as you think - Page 6

post #51 of 67
the problem with more cores is simple. its the managing of them, how to feed them with data, latency etc. we have already seen that, example is simple, hd 5k. doubling up the shaders numbers bringed lowe performance of single shader vs 4k, even if it was produced in lower nm process (55nm vs 40nm) same problem is with huge servers. also its same reason why less and less huge servers are produced, and more and more, smaller is poping out

I have a question, not in regards to this topic.

Is "computer science" over there the equivalent "programming" over here in Australia?

Stuff like: VB, C++, C#, Python and stuff like that ?
post #53 of 67
If you mean in terms of practice and degree, then, yes, essentially. It can include a number of more specific disciplines, of course.
post #54 of 67
Oh ok,

I am studying CERT IV 'in Australia' which covers.

VB and C++
Cisco networking
Web based programming "in pure code and Dreamweaver CS4"
Adobe Illustrator and Photoshop CS4
Data basing in Microsoft Access 2007 and assessment of data and relations.

I will not name all of the 24 modules (course components) but it's the qualification before the diploma.

All of the mentioned (streams/subjects) I thought where going to be boring subjects, but I was quite pleased to find that I am intrigued by them.

I was just wondering how different it is over there for the education system.

Cores are better than threads period. Do they realize this yet? They can say they have 1000 cores but since most of them are virtual (same thing as threads), it's a piece of bull****.

I'm pretty sure one just chooses the courses of interest and that meet certain credit requirements, and take certification tests (i.e. Microsoft, SUN/Oracle, etc.) if desired.

There are a few Cert IV courses at TAFE in Oz. I did "Client Support". We're Off Topic aren't we?

yeah just a bit

Back on topic:

I see the potential of these processors in servers, which most people have said that this could replace a whole rack of servers and only with one unit.

Price is subjective. You have to do a cost-benefit analysis. You really are taking such a simplistic view of the world. Intel and other chipmakers do cost-benefit analysis before embarking on a multi-billion dollar project. Businesses do cost-benefit analysis before make a purchase.

The price on expensive chip can increase and there still be purchases as long as the price increase is gains better performance. This is especially true if the performance per dollar or performance per watt is better.

If a $1000 CPU was replaced by a $10K CPU and the new CPU performs 15 times as fast, then it would be a plus for buyers. While it may push out some smaller buyers, there are still enough big buyers to make it profitable.

If you really want to bring price in picture, you need a better economics background.

You're comparing x86 vs POWER though. You can't compare them just like that with taking into account everything behind it.

i.e. A 747 has 10 wheels and a Civic has 4 wheels. What does A have to do with B other than they both have wheels and are modes of transportation?

Huh?

A core is a core. A thread is a thread. Don't you realize they are two different things? A core is a processing unit while a thread is a term for the lowest unit that can be processed.

While a virtual core is not as good as actual core, it is often worth it due to the cost-benefit (depending on workload). A 5-10% additional die space to implement a better thread scheduler can yield 20-40% performance gains.

Space is a resource. 10 computers generally take up more space then 1

You dont have to take everything into account . Tire advancements made for trucks were passed on to aircraft. Sure one only weight about fifty times more and constantly has to deal with acceleration and deceleration. But if it weren't for the innovation of the trucking industry aircraft might have been limited to even slower landing speeds. Which means more weight, More drag, More fuel

Or a better example is that back in the early days of flight engines were so unreliable that they often had to be change DURING FLIGHT. Many could only fly for about 10 hours before they needed a over haul. Some even only had a life expectancy of 100 hours! The stresses of WWI forced engineers to make more reliable engines. This technology was then carried out to cars making them cheaper faster and more powerful.

The point is. Cars use gears, they often have to rev up and down more often then aircraft engine. But they had the same job to do and that is make a shaft spin in circles.

Any ways your being really literal. I think you understand what i mean...

Fun fact: I used to model for video games. This model with a historically inaccurate paint job. Is the Sopwith 1½ Strutter. It was the first British aircraft to have a synchronized machine gun making it a two seater fighter.
