Since it's a apples to oranges comparison I'm hoping someone smarter than me can help me understand. How does a exahash compare to a exaflop? How does the Bitcoin network really compare in computing power to the largest Supercomputer?
Top Supercomputer -
Frontier
Housed at the Oak Ridge National Laboratory, Frontier has held number one since the June 2022 list. The supercomputer has an HPL (high performance Linpack) benchmark score of 1.194 exaflops, uses AMD Epyc 64C 2GHz processors, and is based on the HPE Cray EX235a architecture.
Exaflop -
An exaflop is a measure of performance for a supercomputer that can calculate at least 1018 or one quintillion floating point operations per second.
In exaflop, the exa- prefix means a quintillion, that’s a billion billion, or one followed by 18 zeros. Similarly, an exabyte is a memory subsystem packing a quintillion bytes of data.
The “flop” in exaflop is an abbreviation for floating point operations. The rate at which a system executes a flop in seconds is measured in exaflop/s.
Floating point refers to calculations made where all the numbers are expressed with decimal points.
Exahash -
Hashrate (Hash per second, h/s) is an SI-derived unit representing the number of double SHA-256 computations performed in one second in the bitcoin network for cryptocurrency mining. Hashrate is also called as hashing power. It is usually symbolized as h/s (with an appropriate SI prefix).
An exahash is 1,000,000,000,000,000,000 hashes per second or one million million million hashes per second.
