Partitioning

Tasks

Tuning

• Add support for setting and reading partitioning threshold in legate::ParallelPolicy, via methods:

  • set_partitioning_threshold() to set the partitioning threshold for a given target processor kind.

  • partitioning_threshold() to read the partitioning_threshold for a given target processor kind.

  This allows users to control partitioning policy for stores for various kinds of target processors, e.g., force partitioning of small stores.

I/O

• Add native support for HDF5 complex types since HDF5 2.0. Users wanting to read/write complex data must have at least HDF5 2.0 installed to enable support.

Partitioning

Tasks

Tuning

• Add support for setting and reading partitioning threshold in legate.core.ParallelPolicy, via methods:

  • set_partitioning_threshold() to set partitioning threshold for a target processor kind.

  • partitioning_threshold() to read the partitioning_threshold for a target processor kind.

  This functionality allows users to control partitioning decisions of stores, for various kinds of target processors, e.g., force partitioning of small stores.

Types

Runtime

Utilities

• Add legate.util.has_started.runtime_has_started() for testing if the legate runtime has started. (Note that the runtime is automatically started by importing legate.core, so this function is only needed in settings where legate.core is not directly imported.)

• Add start_runtime keyword argument to legate.util.info.info() and legate.util.benchmark.benchmark_log(). If start_runtime=False is specified, the runtime will not be started as a side-effect of calling those functions.
