Crystalline: Fast and Memory Efficient Wait-Free Reclamation [article]

Ruslan Nikolaev, Binoy Ravindran
2021 arXiv   pre-print
Moreover, HP are only lock-free in the general case. Recently, several new memory reclamation approaches such as WFE and Hyaline have been proposed.  ...  Historically, memory management based on lock-free reference counting was very inefficient, especially for read-dominated workloads.  ...  OrcGC [11] is another lock-free garbage collector with great performance, but it can be slower in some tests than hazard pointers.  ...

VBR: Version Based Reclamation [article]

Gali Sheffi, Maurice Herlihy, Erez Petrank
2021 arXiv   pre-print
In this work we present a new reclamation scheme called version based reclamation (VBR), which provides a full optimistic solution to lock-free memory reclamation, obtaining lock-freedom and high efficiency  ...  Safe lock-free memory reclamation is a difficult problem. Existing solutions follow three basic methods (or their combinations): epoch based reclamation, hazard pointers, and optimistic reclamation.  ...  Orcgc: automatic lock-free memory reclamation.  ...
