Title: Oakridge just unveiled 1 exaflop computing. So how much is Bitcoin hashrate is?

hashrate in exaflop?

IS it 211.5 EH/s or 211.5 exaflop aka more than 211 times than of the fastest supercomputer?

The current network hashrate is around 80,700,000 PetaFLOPS (https://www.simplilearn.com/things-you-didnt-know-about-bitcoin-article)
So if you care for these types of comparisons a bit above 80,700 times faster ;D

You cannot make a direct comparison.

FLOPS are floating point operations per second. Floating point numbers are the real numbers - i.e. numbers with a decimal point.
The bitcoin network uses hash functions, which works with integers, not real numbers.

The number of FLOPS that this supercomputer can calculate is not directly related to the number of hashes per second it can calculate. The reverse is also true - ASICs can calculate an enormous number of hashes per second, but cannot calculate any FLOPS. Indeed, since this supercomputer will be massively optimized to squeeze every last available FLOPS out of it, it will be very inefficient when considering other operations, such as hashing. When it comes to bitcoin mining, this supercomputer will likely be vastly outperformed by ASICs.

Is a baby panda faster than an apple?  ;D

Just one funny thing, besides what o_e_l_e_o mentioned, even if that supercomputer would be mining at 1 exahash, it would still be a highly inefficient gear costwise, it did cost $600million, for that you can get around 78 000 Asics at spot prices that will give you around 8.5 exahash per second  ;D
But no, we're talking about two different things built for different purposes.

The page simply uses the following assumptions/estimates:

    1 INTOP = 2 FLOP
    1 hash = 6.35K INTOP
    1 hash = 12.7K FLOP

So the hashrate in TeraFLOP/s is simply 12.7 times the hashrate in Gigahashes/s.

As an example:  11,558.55 Gigahashs/s * 12.7 TeraFLOP/Gigahash = 146,794 TeraFLOP/s = 146 PetaFLOP/s

This is more of a guesstimation  than a calculation.
Even if they compare 11 yr old apples with 11yr old oranges I would say it's close enough for this discussion's sake...  :P
