- massive simulations
- they mean maths
The term number-crunching refers to large-scale numerical simulationsNow simulations of spacecraft flight or the effects of adding a dam to a major river really are typical uses of hpc
However, thinking about (2 ... they mean maths), you have many uses of hpc where the Mathematics itself is the outcome.
For people who are learners of hpc, I can see why the 'massive simulations' message is preferred as a way of presenting the utility of hpc
However as a Mathematician I naturally think also of many scenarios where the Mathematics is the outcome.
Not all of those outcomes will be moved onto a powerful workstation in the next decade.
There is also another major use of hpc which is not really [in my opinion] a good fit for the word simulation. Natural language processing at very high speed is one of the prerequisites of AI.
In such a context you are not simulating the process of adding meaning to raw words, you are actually doing it when you task a hpc with such processing.
