Where would I find information on the fastest computers in the world?
Here is a list
can u convert 280.6 TFlop/s to a more managable unit?
also, how fast is one megaflop
Well I do not understand your question.
A flop is one floating point operation (an operation on a non-integer).
How fast is a Teraflop?
Can someone convert 280.6 TFlop/s to more managable units?
also, how fast is a megaflop?
What exactly is a cluster?
How fast are the fastest clusters, and does anyone know how fast the cluster(s) is/are at the University of Richmond?
how many flops/s can any ordinary pc run? and how would i compare that to the fastest (280.6 TFlop/s)
woops. not how fast, but how many flops are in a megaflop, or a teraflop?
Mega and tera are both greek words.
Mega stands for 1 000 000
Tera stands for 1 000 000 000 000
prefix mega means 10^6 over the basic unit.
prefix giga means 10^9 over the basic unit.
prefix terra means 10^12 ............
so there are 1.000.000.000.000 flops in a terra flop
1.000.000.000 flops in a giga flop and so on....
These prefixes can be applied to any unit, not just to flops(i.e. MegaByte but here is a kinda different story because the basic units are in bynary not decimal.)
A megaflop is a measure of a computer's speed and can be expressed as:
A million floating point operations per second
10 to the 6th power floating-point operations per second
2 to the 20th power FLOPS
megaFLOPS (MFLOPS) is equal to one million floating-point operations per second, and a gigaFLOPS (GFLOPS) is equal to one billion floating-point operations per second. A teraFLOPS (TFLOPS) is equal to one trillion floating-point operations per second.
You should be able to calculate it with this information.
Well, 'terra' actually means 'ground' or 'land'.
It's 'tera' which is 1000 times bigger than 'giga'!
First, you know what the prefixes mean, right?
Kilo = 1,000
Mega = 1,000,000
Giga = 1,000,000,000
Tera = 1,000,000,000,000
For the processing power of pc's, hardware review sites have them. Here is a sample: http://www.tomshardware.com/2006/07/14/core2_duo_knocks_out_athlon_64/page16.html
Newer pc's are on the order of 10-20 gigaflops, so about 10,000 times slower than a supercomputer (which, incidentally, are often just clusters of several thousand desktop processors).
It is a term used in astrophysics, physics, chemistry, computer programming, computer disk drives. Maybe they have some really fast computers at the University of Richmond.

Serious Help needed
how do i found out how to run a test on a cluster to find out the speed?
Well that depends what you want to measure.
Is it pure CPU speed, for each CPU separately or on how they work togeter? Or is it disk throughput, like for some database application, network server performance? There are many things you can measure.
So it would help if you provided some more information.
How do i find out the speed of a cluster? I'm supposed to figure how to run a program to determine the speed of our cluster here at UR.
That's a rather vague question, as we don't know anything about UR's cluster. This sounds like some kind of a lab, though, meaning you should probably have some sort of handout that provides help.
There may a simple benchmarking program provided for you. Or maybe you have to write your own. If you have to write your own, of course, you'd have to use some kind of cluster library (MPI, etc.) to distribute the work across all the nodes in the cluster, which could be difficult.
If you have some kind of background information, you should provide it as part of your question. Otherwise, there's really nothing we can do to help you.
I dont know really. I was told to just figure out how to determine how many megaflop/s its running and compare it to other clusters (specifically the faster ones). Should I have been given more information or what?
