Resolve a loop block size for multi-dimensional array tiled loops.
npm install @stdlib/ndarray-base-tiling-block-sizeWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Resolve a loop block size for multi-dimensional array tiled loops.
``bash`
npm install @stdlib/ndarray-base-tiling-block-size
`javascript`
var blockSize = require( '@stdlib/ndarray-base-tiling-block-size' );
#### blockSize( dtypes )
Resolves a loop block size for multi-dimensional array tiled loops according to provided ndarray [data types][@stdlib/ndarray/dtypes].
`javascript`
var bsize = blockSize( [ 'float64', 'float64', 'float64', 'float64' ] );
// returns
The function supports the following arguments:
- dtypes: list of input and output ndarray [data types][@stdlib/ndarray/dtypes].
- The returned loop tiling block size is in units of elements.
`javascript
var dtypes = require( '@stdlib/ndarray-dtypes' );
var cartesianPower = require( '@stdlib/array-base-cartesian-power' );
var promoteDataTypes = require( '@stdlib/ndarray-base-promote-dtypes' );
var blockSize = require( '@stdlib/ndarray-base-tiling-block-size' );
// Generate a list of input ndarray dtype triplets:
var dt = cartesianPower( dtypes(), 3 );
// Resolve the block size for each dtype triplet and its promoted dtype...
var t;
var b;
var i;
console.log( 'block_size, xdtype, ydtype, zdtype, wdtype' );
for ( i = 0; i < dt.length; i++ ) {
t = promoteDataTypes( dt[ i ] );
dt[ i ].push( ( t === null ) ? 'generic' : t );
b = blockSize( dt[ i ] );
console.log( '%d, %s, %s, %s, %s', b, dt[i][0], dt[i][1], dt[i][2], dt[i][3] );
}
