rocRAND

rocRAND code for ROCm 5.2.1 did not change. The library was rebuilt for the updated ROCm 5.2.1 stack.

Added

• Backward compatibility for deprecated #include <rocrand.h> using wrapper header files.
• Packages for test and benchmark executables on all supported OSes using CPack.

rocRAND code for ROCm 5.1.3 did not change. The library was rebuilt for the updated ROCm 5.1.3 stack.

rocRAND code for ROCm 5.1.1 did not change. The library was rebuilt for the updated ROCm 5.1.1 stack.

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 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 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.

Changed

• No updates or changes for ROCm 5.0.0.

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.

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.

No changes made for ROCm 4.3.1.

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.

Fixed

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

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

• rocRAND benchmark performance drop has been fixed.
• Debug builds via the install script have been fixed.
