This function is relatively slow and should only be used for large areas consisting of multiple pages. The interleaving works at page level and will only show an effect when the area is large. The allocated memory must be freed with numa_free (). floatplane training in florida

Web18 mei 2024 · numa_alloc_* family for shared memory. There are multiple ways to get shared memory (mmap, shmat etc.), and adding them all to the library would be quite complicated. Keeping the allocation of shared memory to the application and just providing "police" functions to change the policy seemed simpler. WebDuring system boot up, the temporary interleaved system default policy works in this mode. MPOL_PREFERRED_MANY. This mode specifices that the allocation should be preferrably satisfied from the nodemask specified in the policy. If there is a memory pressure on all nodes in the nodemask, the allocation can fall back to all existing numa nodes.
