parallel.gpu.RandStream.list

Random number generator algorithms on the GPU

Syntax

parallel.gpu.RandStream.list

Description

parallel.gpu.RandStream.list lists the generator algorithms that can be used when creating a random number stream with parallel.gpu.RandStream or parallel.gpu.RandStream.create.

Examples

Available Generators on the GPU

When you use parallel.gpu.RandStream.list, MATLAB^® displays a list of the available random number generators.

parallel.gpu.RandStream.list

The following random number generator algorithms are available:
 
MRG32K3A:         Combined multiple recursive generator (supports parallel streams)
Philox4x32_10:    Philox 4x32 generator with 10 rounds (supports parallel streams)
Threefry4x64_20:  Threefry 4x64 generator with 20 rounds (supports parallel streams)

Each of these generators supports multiple parallel streams.

Keyword	Generator	Multiple Stream and Substream Support	Approximate Period in Full Precision
"Threefry" or "Threefry4x64_20"	Threefry 4x64 generator with 20 rounds	Yes	2514 (2256 streams of length 2258)
"Philox" or "Philox4x32_10"	Philox 4x32 generator with 10 rounds	Yes	2193 (264 streams of length 2129)
"CombRecursive" or "mrg32k3a"	Combined multiple recursive generator	Yes	2191 (263 streams of length 2127)
