GPU-optimized algo should be much faster than the CPU one, before ASICs Bitcoin was briefly mined on GPUs

Conceivably, you could run multiple instances of this program at the same time to get more output out of your laptop, right? Surely this isn't making the most out of a multi-core processor?

I realize the difference between an ASIC and this is still astronomical, but for the sake of argument.

Holy shit! The hashrate is at 512 EH/s now!

var crypto = require( 'crypto' )
var sha256 = s => {
    if ( typeof s == "string" ) s = new TextEncoder().encode( s );
    return crypto.subtle.digest( 'SHA-256', s ).then( hashBuffer => {
        var hashArray = Array.from( new Uint8Array( hashBuffer ) );
        var hashHex = hashArray
            .map( bytes => bytes.toString( 16 ).padStart( 2, '0' ) )
            .join( '' );
        return hashHex;
    });
}

var i = 0;
var hasher = async () => {
    var hash = await sha256( `test ${i}` );
    i = i + 1;
    if ( String( i ).endsWith( "00000" ) ) console.log( i );
    if ( i < 1000000 ) hasher();
}
hasher();
