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)
