Grid Computing
By how much does running a grid computer setup increase calculation speed? For example if I have computers that can run x calculations per second and I put 4 of them in a grid, does that make the calculation speed 4x or x^4? Also, are there any free/open source grid computing applications?
Thanks. |

I won't pretend I know the answer to this, but speaking from a MATHEMATICAL standpoint, its 4X.
Look at 4x...you have four computers....so thats FOUR times the calculations. If the computer can do 100 calculations, thats 400 calculations. Look at x^4...Then youd have a number much higher than any of the computers are capable of, even when working together. (100,000 calculations)

firstly you need to consider if the appilcation doing the calculation is optimised to use all the cores. Even if it was there are speed penalties for linking multiway cpus together. i would hate to quantify the benefits but something like 3x would be possible IF the software were very optomised |
