i will start by asking a question then whoever answers correctly will ask the next

#1 What is the fastest "super-computer"?
(hint: this is from 2002 or b4)

In 2002, the NEC Earth Simulator located in Japan was the fastest supercomputer.

As of now, the IBM BlueGene is the fastest supercomputer.

#2. You have 3 resistors in a parallel circuit.

-The power source is 17.299v.
-R1 is 680 ohms.
-R2 is 1500 ohms.
-R3 is 470 ohms.

Knowing this information, calculate the following:

RT (resistance total)
IT (current total)
IR1 (current passing through R1)
IR2 (current passing through R2)
IR3 (current passing through R3)
VR1 (voltage passing through R1)
VR2 (voltage passing through R2)
VR3 (voltage passing through R3)
PT (power total)
PR1 (power passing through R1)
PR2 (power passing through R2)
PR3 (power passing through R3)

my source saye the RA/6000 ASCI White
but ill give it to you cause you prolly know more than me.

The ASCI White can only do 12.3 teraflops. The NEC Earth Simulator can do 40 teraflops and the IBM BlueGene can do 360 teraflops.

Oh, and I edited my above post to include question #2.

This is what I came up with after doing some calculations, "electric theory" isn't one of my fields of expertise. Hopefully I will be corrected if there are mistakes and I will learn from them.

RT (resistance total)=680ohms
IT (current total)=0.073778755A
IR1 (current passing through R1)=0.025439705A
IR2 (current passing through R2)=0.011532666A
IR3 (current passing through R3)=0.036806382A
VR1 (voltage passing through R1)=17.299V
VR2 (voltage passing through R2)=17.299V
VR3 (voltage passing through R3)=17.299V
PT (power total)=1.276298692W
PR1 (power passing through R1)=0.440081472W
PR2 (power passing through R2)=0.1995036W
PR3 (power passing through R3)=0.636713619W

it is wrong.. total resitance should be 234ohms
i'll be damned if im gonna sit and work out the rest

Except for the RT, you got every one right.

The formula to calculate the RT is:

(1/(1/R1+1/R2+1/R3))

So to input the numbers into the formula would make it as shown:

(1/(1/680+1/1500+1/470)) = as apj101 said, 234.47 Ohms.

If we could get even a drop of this kind of intellegence over in the OffTopic section I think all our problems would be solved! :p

I think it goes to apj this time...

But I did get everything else right except for the total resistance. apj only posted the correct total resistance.

just a suggestion, whoever gets to post the question, make a title for it, so ppl can find the current question easier ;)

Someone just make a question:)...

I think we could deal with two questions at one time if it came down to it....

I guess I'll go ahead and give you the questions. This may be easy for some.

What is the name of the upcoming socket for the Opteron series of CPU's?
How many pins does it feature?
What kind of memory will it have support for?
