rocRAND 2.10.13 for ROCm 5.1.0

Added

• Generating a random sequence different sizes now produces the same sequence without gaps
  indepent of how many values are generated per call.
  • Only in the case of XORWOW, MRG32K3A, PHILOX4X32_10, SOBOL32 and SOBOL64
  • This only holds true if the size in each call is a divisor of the distributions
    output_width due to performance
  • Similarly the output pointer has to be aligned to output_width * sizeof(output_type)

Changed

• hipRAND split into a separate package
• Header file installation location changed to match other libraries.
  • Using the rocrand.h header file should now use #include <rocrand/rocrand.h>, rather than #include <rocrand/rocrand.h>
• rocRAND still includes hipRAND using a submodule
  • The rocRAND package also sets the provides field with hipRAND, so projects which require hipRAND can begin to specify it.

Fixed

• Fix offset behaviour for XORWOW, MRG32K3A and PHILOX4X32_10 generator, setting offset now
  correctly generates the same sequence starting from the offset.
  • Only uniform int and float will work as these can be generated with a single call to the generator

Known issues

• kernel_xorwow unit test is failing for certain GPU architectures.

rocRAND-2.10.12 for ROCm 5.0.2

rocRAND code for ROCm 5.0.2 is unchanged from rocRAND for ROCm 5.0.1. The library was rebuilt for the updated ROCm 5.0.2 stack.

rocRAND-2.10.12 for ROCm 5.0.1

rocRAND code for ROCm 5.0.1 is unchanged from rocRAND for ROCm 5.0.0. The library was rebuilt for the updated ROCm 5.0.1 stack.

rocRAND-2.10.12 for ROCm 5.0.0

Changed

• No updates or changes for ROCm 5.0.0.

rocRAND-2.10.12 for ROCm 4.5.2

rocRAND code for ROCm 4.5.2 is unchanged from rocRAND for ROCm 4.5.0. The library was rebuilt for the updated ROCm 4.5.2 stack.

rocRAND-2.10.12 for ROCm 4.5.0

Addded

• Initial HIP on Windows support. See README for instructions on how to build and install.
• Sobol64 support added.
• Benchmark time measurement improvement
• Address Sanitizer build option added.

Changed

• Packaging split into a runtime package called rocrand and a development package called rocrand-devel. The development package depends on runtime. The runtime package suggests the development package for all supported OSes except CentOS 7 to aid in the transition. The suggests feature in packaging is introduced as a deprecated feature and will be removed in a future rocm release.

Fixed

• Fix for mrg_uniform_distribution_double generating incorrect range of values
• Fix for order of state calls for log_normal, normal, and uniform

Known issues

• kernel_xorwow test is failing for certain GPU architectures.
• nvcc backend fix
• Fix ranges of MRG32k3a device functions.

rocRAND-2.10.10 for ROCm 4.3.1

No changes made for ROCm 4.3.1.

rocRAND-2.10.10 for ROCm 4.3.0

Added

• gfx90a support added.
• gfx1030 support added
• gfx803 supported re-enabled

Fixed

• Memory leaks in Poisson tests has been fixed.
• Memory leaks when generator has been created but setting seed/offset/dimensions throws an exception has been fixed.

rocRAND-2.10.9 for ROCm 4.2.0

Fixed

• rocRAND benchmark performance drop for xorwow has been fixed for older ROCm builds.

rocRAND-2.10.8 for ROCm 4.1.0

Added

• Ability to force install dependencies with new -d flag in install script

Changed

• rocRAND package name has been updated to support newer versions of ROCm.

Fixed
