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.

KeywordGeneratorMultiple Stream and Substream SupportApproximate Period in Full Precision
"Threefry" or "Threefry4x64_20"Threefry 4x64 generator with 20 roundsYes2514 (2256 streams of length 2258)
"Philox" or "Philox4x32_10"Philox 4x32 generator with 10 roundsYes2193 (264 streams of length 2129)
"CombRecursive" or "mrg32k3a"Combined multiple recursive generatorYes2191 (263 streams of length 2127)
