rocRAND 3.1.0 for ROCm 6.2.0

Additions

• Added rocrand_create_generator_host
  • The following generators are supported:
    • ROCRAND_RNG_PSEUDO_MRG31K3P
    • ROCRAND_RNG_PSEUDO_MRG32K3A
    • ROCRAND_RNG_PSEUDO_PHILOX4_32_10
    • ROCRAND_RNG_PSEUDO_THREEFRY2_32_20
    • ROCRAND_RNG_PSEUDO_THREEFRY2_64_20
    • ROCRAND_RNG_PSEUDO_THREEFRY4_32_20
    • ROCRAND_RNG_PSEUDO_THREEFRY4_64_20
    • ROCRAND_RNG_PSEUDO_XORWOW
    • ROCRAND_RNG_QUASI_SCRAMBLED_SOBOL32
    • ROCRAND_RNG_QUASI_SCRAMBLED_SOBOL64
    • ROCRAND_RNG_QUASI_SOBOL32
    • ROCRAND_RNG_QUASI_SOBOL64
  • The host-side generators support multi-core processing. On Linux, this requires the TBB (Thread Building Blocks) development package to be installed on the system when building rocRAND (libtbb-dev on Ubuntu and derivatives).
    • If TBB is not found when configuring rocRAND, the configuration is still successful, and the host generators are executed on a single CPU thread.
• Added the option to create a host generator to the Python wrapper
• Added the option to create a host generator to the Fortran wrapper
• Added dynamic ordering. This ordering is free to rearrange the produced numbers,
  which can be specific to devices and distributions. It is implemented for:
  • XORWOW, MRG32K3A, MTGP32, Philox 4x32-10, MRG31K3P, LFSR113, and ThreeFry
• For the NVIDIA platform compilation using clang as the host compiler is now supported.
• C++ wrapper:
  • lfsr113_engine now also supports being constructed with a seed of type unsigned long long, not only uint4.
  • added optional order parameter to constructor of mt19937_engine
• Added the following functions for the ROCRAND_RNG_PSEUDO_MTGP32 generator:
  • rocrand_normal2
  • rocrand_normal_double2
  • rocrand_log_normal2
  • rocrand_log_normal_double2
• Added rocrand_create_generator_host_blocking which dispatches without stream semantics.
• Added host-side generator for ROCRAND_RNG_PSEUDO_MTGP32.
• Added offset and skipahead functionality to LFSR113 generator.
• Added dynamic ordering for architecture gfx1102.

Changes

• For device-side generators, you can now wrap calls to rocrand_generate_* inside of a hipGraph. There are a few
  things to be aware of:
  • Generator creation (rocrand_create_generator), initialization (rocrand_initialize_generator), and destruction (rocrand_destroy_generator) must still happen outside the hipGraph.
  • After the generator is created, you may call API functions to set its seed, offset, and order.
  • After the generator is initialized (but before stream capture or manual graph creation begins), use rocrand_set_stream to set the stream the generator will use within the graph.
  • A generator's seed, offset, and stream may not be changed from within the hipGraph. Attempting to do so may result in unpredicable behaviour.
  • API calls for the poisson distribution (eg. rocrand_generate_poisson) are not yet supported inside of hipGraphs.
  • For sample usage, see the unit tests in test/test_rocrand_hipgraphs.cpp
• Building rocRAND now requires a C++17 capable compiler, as the internal library sources now require it. However consuming rocRAND is still possible from C++11 as public headers don't make use of the new features.
• Building rocRAND should be faster on machines with multiple CPU cores as the library has been
  split to multiple compilation units.
• C++ wrapper: the min() and max() member functions of the generators and distributions are now static constexpr.
• Rename and unify the existing ROCRAND_DETAIL_.*_BM_NOT_IN_STATE to ROCRAND_DETAIL_BM_NOT_IN_STATE
• Static & dynamic library: moved all internal symbols to namespaces to avoid potential symbol name collisions when linking.

Deprecations

• Deprecated the following typedefs. Please use the unified state_type alias instead.
  • rocrand_device::threefry2x32_20_engine::threefry2x32_20_state
  • rocrand_device::threefry2x64_20_engine::threefry2x64_20_state
  • rocrand_device::threefry4x32_20_engine::threefry4x32_20_state
  • rocrand_device::threefry4x64_20_engine::threefry4x64_20_state
• Deprecated internal header: src/rng/distribution/distributions.hpp
• Deprecated internal header: src/rng/device_engines.hpp

Removals

• Removed references to and workarounds for deprecated hcc.
• Support for HIP-CPU

Known issues

• SOBOL64 and SCRAMBLED_SOBOL64 generate poisson-distributed unsigned long long int numbers instead of unsigned int. This will be fixed in the next major release.
