Persistent Compilation Cache

Reactant.jl supports a persistent compilation cache that caches compiled and autotuned kernels on disk. We use XLA's persisted autotuning for this purpose. By default, the autotuning cache is enabled.

Preferences

• persistent_cache_enabled: Whether to enable the persistent compilation cache. Defaults to false.

• persistent_cache_directory: The base directory to use for the persistent compilation cache. Note that it is recommended to not set this preference, as Reactant will create a unique directory corresponding to XLA and Reactant_jll's version. If the user sets this preference, it is the user's responsibility to ensure that the directory exists and is writable and needs to be segregated based on XLA and Reactant_jll's version. Defaults to "".

• persistent_kernel_cache_enabled: Whether to enable the kernel cache. Defaults to false.

• persistent_autotune_cache_enabled: Whether to enable the autotuning cache. Defaults to true.

Clearing the cache

To clear the cache, you can use Reactant.clear_compilation_cache!:

using Reactant
clear_compilation_cache!()
