Is there a simple way to find out the power of cluster/node/supercomputer?

Question

I know there are some unix utils for simple architecture queries:

arch 
nproc
lsb_release -a

are there any simple ways to find out about the cluster/supercomputer/nodes - like to find out the number of teraflops of the machine and so on?

Answer 1

Short answer: no.

Slightly longer answer: no. You have to run benchmarks to measure those. The information should be available from the owners/administrators of the supercomputer in question.
