cuda.core 0.X.Y Release Notes

Released on TBD

Highlights

• Fix for :class:`LaunchConfig` grid parameter unit conversion when thread block clusters are used.

Breaking Changes

• LaunchConfig grid parameter interpretation: When :attr:`LaunchConfig.cluster` is specified, the :attr:`LaunchConfig.grid` parameter now correctly represents the number of clusters instead of blocks. Previously, the grid parameter was incorrectly interpreted as blocks, causing a mismatch with the expected C++ behavior. This change ensures that LaunchConfig(grid=4, cluster=2, block=32) correctly produces 4 clusters × 2 blocks/cluster = 8 total blocks, matching the C++ equivalent cudax::make_hierarchy(cudax::grid_dims(4), cudax::cluster_dims(2), cudax::block_dims(32)).

New features

None.

New examples

None.

Fixes and enhancements

• Improved :class:`DeviceMemoryResource` allocation performance when there are no active allocations by setting a higher release threshold (addresses issue #771).
• Fix :class:`LaunchConfig` grid unit conversion when cluster is set (addresses issue #867).
