| H A D | mt_stackshot.md | 68 Stackshot uses a basic per-cluster bump allocator to allocate space within the
69 buffer. Each cluster gets its own bump allocator to mitigate cache contention,
70 with space split evenly between each cluster. If a cluster runs out of buffer
73 Memory that is freed is put into a per-cluster freelist. Even if the data was
74 originally allocated from a different cluster's buffer, it will be put into the
75 current cluster's freelist (again, to reduce cache effects). The freelist is a
76 last resort, and is only used if the current cluster's buffer space fills.
