Confusion about converting points to flops.

So WCG = 700,000 points = 100,000 BOINC credits = 1 TFL . So if a 1Gflop machine produces 1400 WCG points a day then say if I am producing on average 50,000 WCG points a day from all my machines that is the equivalent output of a single 35GFLOP computer right? Am I wrong?

Now is that the equivalent that a 35GFLOP machine could do in a day or just in a second?

Now I'm confused at what this means too. When the WCG total is said to be at around 500 TFLOPS does that mean the sum total of all that was computed could be done by a 500TFLOP supercomputer in a single day, a single hour, single second? Or does that mean the WCG project is on average computing the same amount as a 500TFLOP computer does in a day?

So basically does that 500TFLOP number (same with my 35GFLOP avg output) is it the sum total of all computations done that could be computed with an equivalent supercomputer at that speed per second OR just that the project is producing the same amount of computations each day as an equivalent supercomputer at that speed?

I don't know how else to explain my confusion, sorry if I'm not making sense.

Re: Confusion about converting points to flops.

I think you are confusing FLOP and FLOPS.
FLOPS means Floating point Operarions per Second.
So a 500 TFLOPS machine does 500 billion floating point operations per second.
If someone sais 'a 500 TFLOP machine' you can assume they mean 500 TFLOPS.

Hope this takes away some of the confusion wink.

For us on the other side of the pond that would be 500 trillion floating point operations per second or 5*10^14.

(European billion = U.S. trillion)

It's true, and yet another source of confusion. Read all about it here. Look for the 'short scale' and 'long scale' column in the table.
Good luck. wink

Snurk's link helped. It still kinda makes me want to bang my head on my desk, but in a different way.
