June 2013 – Today: Tianhe-2 With the Tianhe-2, a machine capable of performing more than 33 quadrillion calculations per second at launch, China once again took the top spot from the US and, so far, has managed to hold onto it. Deployed at the National Supercomputer Center in Guangzho, it is the successor to the Tianhe-1. The Tianhe-2, otherwise known as the Milky Way 2, has 16,000 nodes, each with two Intel Xeon E5 Ivy Bridge processors and three Xeon Phi 31SP co-processors, for a combined total of 3,120,000 computing cores. This architecture allows it to carry out a massive

What is the difference between average, mean, median, and mode?

By • • Knowledge, Teaching • • 1 minute of reading

Mean (or arithmetic mean) is a type of average. It is computed by adding the values and dividing by the number of values. Average is a synonym for arithmetic mean – which is the value obtained by dividing the sum of a set of quantities by the number of quantities in the set. An example is (3 + 4 + 5) ÷ 3 = 4. The average or mean is 4. Two other common forms of averages are the median and mode. The median is the middle value of the set when they are ordered by rank – or the
