In RCW79 we learned about a cosmic bubble (RCW79) that has a diameter of approximately
70 light-years. We computed this to be about
411.6 trillion miles.411.60 trillion is 411,600,000,000,000 411,600,000,000,000 is 411.6 x 1012
The 07 April 2005 posting to the GDT::Blog:: Grid Utilitarian was about the IBM Blue Gene/L supercomputer at Lawrence Livermore National Laboratory hitting a processing speed of
135.3 trillion flops.
A flop is a floating-point operation. In a nutshell, a flop is an arithmetic operation where one of the operands is a decimal number where at least one digit to the right of the decimal point is not zero). Flops are the number of floating-point operations per second.
Let's compare RCS79 with BlueGene/L by dropping the units of measurements and looking only at the numbers.cosmic bubble: 411.6 trillion = 411,600,000,000,000 supercomputer: 135.3 trillion = 135,300,000,000,000
With respect to the supercomputer, it does
135.3 trillioncalculations per second. It sort of begs of the question... how many calculations can it do in a day?given: 86400 seconds per day 135.3 x 86400 = 11,689,920
The IBM BlueGene/L supercomputer can do
11,689,920 trillioncalculations in a day.11,689,920 trillion = 11,689,920,000,000,000,000 supercomputer: 11,689,920,000,000,000,000 cosmic bubble: 411,600,000,000,000 11,689,920,000,000,000,000 = 11.68992 quintillion. 11.68992 quintillion = 11.68992 x 1018
There are concerns that computer processing speeds will be limited because of the speed of light. Some researchers are trying to "slow down" the speed of light.
The IBM Blue Gene/L at Lawrence Livermore National Laboratory is still being built. When completed, it may be able to do
360 trillion flops.
