@stdlib/ndarray-base-unary-tiling-block-size NPM

unaryBlockSize

Resolve a loop block size for multi-dimensional array tiled loops.

Installation

npm install @stdlib/ndarray-base-unary-tiling-block-size

Usage

var unaryBlockSize = require( '@stdlib/ndarray-base-unary-tiling-block-size' );

unaryBlockSize( dtypeX, dtypeY )

Resolves a loop block size according to provided ndarray dtypes for multi-dimensional array tiled loops applying a unary function.

var bsize = unaryBlockSize( 'float64', 'float64' );
// returns <number>

Notes

The returned loop tiling block size is in units of elements.

Examples

var dtypes = require( '@stdlib/ndarray-dtypes' );
var cartesianSquare = require( '@stdlib/array-base-cartesian-square' );
var unaryBlockSize = require( '@stdlib/ndarray-base-unary-tiling-block-size' );

// Generate a list of ndarray dtype pairs:
var dt = cartesianSquare( dtypes() );

// Resolve the block size for each dtype pair...
var b;
var i;
for ( i = 0; i < dt.length; i++ ) {
    b = unaryBlockSize.apply( null, dt[ i ] );
    console.log( '%d, %s, %s', b, dt[i][0], dt[i][1] );
}

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
