XPU out of memory error with Intel Arc Graphics (Meteor Lake) despite sufficient system memory and reported XPU capacity

8

The root cause is that the current XPU runtime limits single allocations to ~4GB by default.

Solution:
Enable “UR_L0_USE_RELAXED_ALLOCATION_LIMITS”:

export UR_L0_USE_RELAXED_ALLOCATION_LIMITS=1

Restart your terminal and try again — the 4GB allocation should succeed.
