Based on the HPE Cray EX235a architecture, the system uses 3rd Gen AMD EPYC 64-core processors with a 2 GHz frequency. In total, the system has 8,730,112 cores that work in conjunction with AMD Instinct MI250X GPUs.

If we could get someone who have that CPU and GPU to run Bitcoin mining software, we could get rough Bitcoin hashrate on this supercomputer Roll Eyes

.

Edit: I found benchmark list on CPUMiner at https://openbenchmarking.org/test/pts/cpuminer-opt. Perhaps someone could make rough estimation from it.

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... Tongue

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

Is a baby panda faster than an apple? Grin

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 Grin

But no, we're talking about two different things built for different purposes.

hashrate in exaflop?

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.

The current network hashrate is around 80,700,000 PetaFLOPS
So if you care for these types of comparisons a bit above 80,700 times faster Grin
