4-9

This new option is the default 'NormalTransform' setting when using the

Philox4x32-10 or Threefry4x64-20 generator. The following commands, therefore,

use 'BoxMuller' for 'NormalTransform':

parallel.gpu.rng(0,'Philox4x32-10')

parallel.gpu.rng(0,'Threefry4x64-20')

Note The 'BoxMuller' option is not supported for the CombRecursive (mrg32k3a)

generator

Compatibility Considerations

In previous releases, the default 'NormalTransform' setting when using the

Philox4x32-10 or Threefry4x64-20 generator on a GPU was 'Inversion'. If you

used either of these generators with the default 'NormalTranform' and you want to

continue with the same behavior, you must explicitly set the 'NormalTransform' with

either of these commands:

stream = parallel.gpu.RandStream('Philox4x32-10','NormalTransform','Inversion')

parallel.gpu.RandStream.setGlobalStream(stream)

stream = parallel.gpu.RandStream('Threefry4x64-20','NormalTransform','Inversion')

parallel.gpu.RandStream.setGlobalStream(stream)

Upgraded MPICH2 Version

The parallel computing products are now shipping MPICH2 version 1.4.1p1 on all

platforms.

Compatibility Considerations

If you use your own MPI builds, you might need to create new builds compatible with this

latest version, as described in Use Different MPI Builds on UNIX Systems.

Discontinued Support for GPU Devices of Compute Capability 1.3

In a future release, support for GPU devices of compute capability 1.3 will be removed. At

that time, a minimum compute capability of 2.0 will be required.
