UMF

✓ import umf

✗ from umf import UMF

Initializes UMF and creates a memory pool to allocate and free memory. Replace 'JUMA' with appropriate pool type for your hardware.

from umf import UMF # Initialize UMF umf = UMF() # Create a memory pool (example: JUMA pool) pool = umf.create_pool('JUMA') # Allocate memory ptr = pool.alloc(1024) print(f"Allocated 1024 bytes at {ptr}") # Free memory pool.free(ptr)

Debug

Known issues

breakingIn UMF 0.10.0, the parameters API changed from direct struct access to a new set/get API. Code using UMF_PARAMS or similar struct fields will break.

fix

Migrate to umfParamsCreate/umfParamsDestroy and parameter setter/getter functions.

affects: <0.10.0

deprecatedUMF_DISABLE_HWLOC option was removed in UMF 1.1.0.

fix

Remove any usage of UMF_DISABLE_HWLOC. hwloc topology is now initialized automatically.

affects: <=1.1.0

gotchaThe Python package 'umf' wraps only a subset of the C library. Some providers (e.g., Level Zero, CUDA) are only available if the C library was built with those backends.

fix

Check UMF documentation for which providers are available in your build. Use umf.supported_providers() to list them.

affects: all
